What is an Outbound proxy? Should I put an Outbound proxy in the field?

An Outbound proxy is mostly used in presence of a firewall/NAT to handle the signaling and media traffic across the firewall. Generally, if you have an outbound proxy and you are not using STUN or other firewall/NAT traversal mechanisms, you can use it. However, if you are using STUN or other firewall/NAT traversal tools, do not use an outbound proxy at the same time.

Can I configure SKYPE or IAX protocol on any Grandstream device?

No, unfortunately both SKYPE and IAX use a proprietary protocol while all Grandstream products follow the SIP protocol Version 2.0 RFC 3261.

Do Grandstream products support IAX/IAX2?

IAX/IAX2 are proprietary protocols and Grandstream does not currently support these protocols.

For BudgeTone 100 Series

BT101 and BT102 models

Off-hook the receiver or press speakerphone.
Press the MENU button
Now dial the IP Address in 12 digit format ex.192168001029
Press SEND.

Note: You will need to have SIP Server field blank, along with NAT traversal set to NO, no STUN Server configured and Use Random Ports set to NO. You can make calls between public IPs and Private IPs under the same LAN.

For GXP2000/GXV3000/BT200 Models

From firmware version 1.1.0.13 onwards, these models have the ability to dial an IP address of another endpoint under the same LAN segment by simply pressing the last octet in the IP address.

In the Advanced Settings page there is an option “Use Quick IP-call mode”, by default it is set to No. When this option is set to YES, and #XXX is dialed, where X is 0-9 and XXX <=255, phone will make direct IP call to aaa.bbb.ccc.XXX where aaa.bbb.ccc comes from the local IP address REGARDLESS of subnet mask.

#XX or #X are also valid so leading 0 is not required (but OK).

eg.
192.168.0.2 calling 192.168.0.3 just dial #3 follow by SEND or #
192.168.0.2 calling 192.168.0.23 just dial #23 follow by SEND or #
192.168.0.2 calling 192.168.0.123 just dial #123 follow by SEND or #

192.168.0.2 dial #3 and #03 and #003 has same effect –> call 192.168.0.3

Note: If you have a SIP Server configured, Direct IP-IP call will still work. However, if you are using STUN, Direct IP-IP call will also use STUN.

Public IP-IP Calling for GXP2000/GXV3000

– Press the round MENU button to enter the GUI.
– Scroll down to Direct IP Call and press the round button to select this option.
– Move the cursor to the blank space above the OK and CANCEL using the round button.

– Take the phone off hook.
– Dial #xxx where x is 0-9 and xxx<255.
-Press # or SEND and a direct IP call to aaa.bbb.ccc.XXX will be completed. “aaa.bbb.ccc” is from the local IP address regardless of subnet mask. The number #xx or #x are also valid. The leading 0 is not required (but it’s OK).

– For example:
192.168.0.2 calling 192.168.0.3 — dial #3 followed by # or “SEND”;
192.168.0.2 calling 192.168.0.23 — dial #23 followed by # “SEND”;
192.168.0.2 calling 192.168.0.123 — dial #123 followed by # “SEND”;
192.168.0.2 dialing #3 and #03 and #003 results in the same call — call 192.168.0.3.

Note: 1. The # will represent colon “:” in direct IP call rather than SEND key as in normal phone call.2. If you have a SIP server configured, direct IP call still works. If you are using STUN, direct IP call will also use STUN.3. Configure the “User Random Port” to “No” when completing direct IP calls.

For GXP2200 Model

– Off hook the phone or select account in the idle screen to bring up call screen on GXP2200.
– Under “Mode Select” button in the call screen, tap on it and select the mode as “IP Call”.

How can I upload a Ringtone on my Grandstream phone?

Linux Version:
Please use the Linux link provided as our phones will only use the format generated by our tools. How to use the tool is attached in the readme file. Be advised that only .wav files can be converted. If you have .mp3 files, they need to be converted to the .wav file format. You can find a free conversion tool online. The ringtone file can not be more than 100KB each. We suggest less than 70KB each. BT100 phone will only take two ring tone files and GXP2000 can take 3 ring tone files.

Windows Version:
Please use the Windows link provided HERE
There are 8 steps to follow using the ringtone generator:

• Upload the ringtones to a computer.
• Save the file as a .wav file.
• Select the appropriate ringtone generator.
• Open the .exe file and then select (and double click) the ringtone file from your files.
• Click “generate ringtone file”. A .bin file will be created in the folder where the .wav file is located.
• Put the ring1/ring2/ring3.bin file under HTTP/TFTP server.
• Enter HTTP/TFTP server IP address in “Firmware Server Path” on Advanced Settings page of web UI.
• Click on UPDATE and REBOOT the device, just like how we do firmware upgrade.
• Then, the phone connects to the HTTP/TFTP server and grabs the ring tone file. After the phone downloads the file, the ringtone can be changed by using keypad or web UI. The config tool doesn’t support .mp3 files.

How do I point my device to a HTTP/TFTP Server?

There are 2 ways to set up your HTTP/TFTP server. Use the device web configuration page. Login to the web configuration pages of your unit. Under Advanced Settings page you will find Firmware Server Path field. Enter the IP Address or server path here. Use the phone keypad. For BudgeTone Phones: From phone keypad, press menu button and down arrow to item number 6, press menu button one more time to get into the “Editing” mode. If the TFTP server IP displayed is not the one you want, enter the entire 12 digits of the IP address of your TFTP server. e.g., if your TFTP server is 192.168.1.100, enter 192168001100. For GXP2000/GXV3000: From phone keypad, press MENU button (round button), scroll down to Config–>Upgrade to enter the Firmware Server information. For ATAs: Unhook the receiver, press ***, press 13, enter IP Address of the Firmware Upgrade Server in 12 digit format ex. 168075215189. Use option 15 to select upgrade protocol (TFTP or HTTP).

How do you setup daylight savings for all products?

US Time Zones:

Pacific: PST+8PDT+7,M3.2.0,M11.1.0
Mountain: MST+7MDT+6,M3.2.0,M11.1.0
Central: CST+6CDT+5,M3.2.0,M11.1.0
Eastern: EST+5EDT+4,M3.2.0,M11.1.0
Note: For GXP2200 that doesn’t have self-defined time zone option, please select the matching time zone under time zone selection list.
Pacific Example:
Time Zone
Since US is west of the Prime Meridian, it will use “+” positive for the offset. Pacific Standard Time (PST) offset is UTC -8:00, so you will change that to PST+8. If you look up PST day light savings, you will find out that it will change to Pacific Daylight Time (PDT) and will move one hour forward (Fall/Autumn BACK, Spring FORWARD). The PDT offset is UTC -7:00, so you will use PDT+7. Daylight Savings
Before we continue, make sure to add a “,” comma. The rest of the syntax is adding the dates where daylight savings takes place. First section is for when daylight savings starts. Second section is for daylight savings ends. “M” is for month and “3” is March, 3rd month of the year. The next number is for the number of the week which is “2”, the second week of the Month. Last number is “0” which stands for the first day of the week which is Sunday. Sunday =0,Monday=1, Tuesday =2, etc. Add another comma “,” to separate between starting and ending daylight savings. Daylight savings ending starts with “M11” which is November, followed by “1” (first week) and “0” (Sunday). If you look up daylight savings US, you’ll find out that it starts on March 10th, (3rd month, 2nd week on Sunday = M3.2.0) and ends on November 3rd (11th month, 1st week on Sunday = M11.1.0).

Is there additional equipment required for my headset to work?

Based on the headsets that we’ve tested we found the below combinations of headsets and quick disconnect cables that work great together on our phones.

Based on the headsets that we’ve tested we found the below combinations of headsets and quick disconnect cables that work great together on our phones.

*Note: All corded headsets require a specific quick disconnect cable.  Please see below to find out what cord is needed with your Plantronics, Jabra, Ovislink, or VXI headset.

What codec should I use for my Grandstream phone?

PCMU (G711u) is used by default. Both PCMU and PCMA will give you toll quality but their bandwidth consumption is also the highest. If your network bandwidth is low, you can choose a lower-bit-rate codec such as G723 or G729 which will give you near toll quality at much smaller bandwidth consumption. If bandwidth is not a concern try using PCMU or PCMA, or even the wideband codec G722 which will provide hi-fidelity voice.

For example: If you have a basic high-speed connection at home (768kbps/128kbps), configure your phone with either G723 or G729 to ensure best available voice quality. If you have T1 bandwidth capacity, configure your phone with either G711 (a/µ) or G722 to experience toll-quality or high-fidelity voice.

What data range we should put for Layer 2 / Layer 3 QoS?

Layer 2 QoS – 802.1q VLAN 802.1p priority
VLAN tag has 12 bits so the value range is from 0 – 4095. 0 means no VLAN
Priority value has 3 bits so the value range is from 0 – 7

Layer 3 QoS – DSCP
It has 6 bits with the range from 0 to 63.

*Note: All corded headsets require a specific quick disconnect cable.  Please see below to find out what cord is needed with your Plantronics, Jabra, Ovislink, or VXI headset.

What if my SIP URI domain is different from the SIP proxy server FQDN (Fully Qualified Domain Name)?

With firmware 1.0.3.60 and later, you can put the your SIP URI domain name into the SIP Server field, and put the actual sip server FQDN into Outbound Proxy field. The phone will use the domain name in SIP Server as part of SIP URI but send and receive SIP messages through the SIP proxy server defined in the Outbound Proxy field.

What is Early Dial? Should I use it?

When you dial a number, if you do not press the “Dial” ( “Redial”) or “#” key if it is configured to function as the “Send” key at the end of your dialed string, the phone will wait for about 4 seconds before timeout and then sends the actual INVITE message. If you set “Early Dial” to be YES, then the phone will attempt to send out INVITE at each key input using the entered dial string collected so far. If the SIP server supports 484 Incomplete Address response, the phone will keep trying with each new key entry until the complete dialed string is entered. This will essentially eliminate the 4-second wait time mentioned above.

Please note that this option can be used ONLY when the SIP server supports 484 Incomplete Address response. Otherwise, any other negative responses from the SIP server (such as 404 Not Found) will cause immediate termination of the call.

What is Early Dial? Should I use it?

STUN stands for Simple Traversal of UDP over NAT. It is a protocol which enables an IP phone to detect the presence and type of NAT behind which the phone is placed. An IP phone that supports STUN can intelligently modify the private IP address and port in its SIP/SDP message by using the NAT mapped public IP address and port through a series of STUN queries against a STUN server located on the public Internet. This will allow SIP signaling and RTP media to successfully traverse a NAT without requiring any configuration changes on the NAT.

STUN presents a working solution for most NATs that are not symmetric NAT, e.g., most of the SOHO routers have non-symmetric NAT and in this case, it is OK to use STUN. However, STUN does NOT work with symmetric NAT and if your routers have built-in symmetric NAT, do not use STUN.

Note: NOT ALL SIP PROXY SERVERS WILL WORK WITH A STUN TRANSLATED SIP MESSAGES, PLEASE CONSULT YOUR SERVICE PROVIDER FOR DETAIL.

What is the difference between “User ID” and “Authentication ID”?

User ID is the user part of the SIP address of the phone and this is usually the information displayed as Caller ID on the LCD. e.g., typically it is a phone number or extension number or a user’s name. Authentication ID is an ID used strictly for authentication purpose when the phone attempts to contact the SIP server. This may or may not be the same as User ID.

What is TR-069 and do Grandstream devices support it?

It is a protocol for communication between CPE (Customer Premise Equipment) and an ACS (Auto Configuration Server) that provides secure auto-configuration as well as other CPE management functions within a common framework. Grandstream devices do support this protocol.Click here for more details.

What number should I use for “Voice Frames per TX”?

It depends on what codec you choose and balance between bandwidth utilization and impact of packet loss. The bigger this value, thehigher bandwidth utilization because more voice frames are packed into the payload field of a UDP/RTP packet and thus the network header overhead would be lower. However, the impact of a packet loss on perceived voice quality will be bigger.

• For PCMU/PCMA, the default is 2 and max is 10
• For G723, the default is 1 and max is 32
• For G726-32, the default is 2 and max is 20
• For G729, the default is 2 and max is 64
• For G728, the default is 4 and max is 64
