If multiple DIDs are bundled with only one sip truck account by service provider, how should I setup the gateway to route calls to different FXS port?
Grandstream GXW IP gateways support call routing based on SIP request URI user ID. This function can help to route calls to different FXS ports within one hunting group. Settings for incoming calls: 1. Fill the sip truck ID, password, and Name in one FXS port and register it. And then, active its Hunting Group in FXS Ports->Advanced Port Settings. 2. Assign the other FXS ports to the activated hunting group. Then, in Request URI Routing ID field, name them with the additional DIDs bundled in your sip truck. Settings for outgoing calls: after finishing the step 2 above, go to Profile X->Sip Settings->Basic Settings and set Use Request Routing ID In SIP Headers to Yes. Once done, gateway will look into the Request URI user ID in the incoming call’s INVITE and route the call to designated FXS Port with matching DID. Also, gateway will replace the From and Contact header in the INVITE for outgoing calls with configured Request URI Routing ID.

My access point won’t pair under the GWN AP controller, what can I do?
Make sure that the GWN AP is connected to same network as the GWN AP acting as the controller.
If it is already discovered, but cannot be paired, please check one of the below causes:

- This unit is already paired under another GWN AP Controller. In this case the unit needs to be unpaired from the previous Controller to make it available for pairing again.
My application with UCM6100/6510 AMI was working on UCM6100/6510 firmware version 126.96.36.199, but it doesn't work anymore after it's upgraded to 188.8.131.52. What should I do?
UCM6100/6510 firmware 184.108.40.206 is using Asterisk 1.8 which has AMI supported. UCM6100/6510 firmware 220.127.116.11 has upgraded to Asterisk 13 which is using AMI v2 (starting in Asterisk 12, the AMI is upgraded to AMI v2). According to Asterisk Wiki https://wiki.asterisk.org/wiki/display/AST/Upgrading+to+Asterisk+12, on AMI v2, many events were changed, and the semantics of channels and bridges were defined. In particular, how channels and bridges behave under transfer scenarios and situations involving multiple parties has changed significantly. Please see the AMI v2 Specification for more information:
Since AMI is provided as-is, please consult with the software vendor to update your application using AMI v2. Or if you wish to downgrade UCM6100/6510 from 18.104.22.168 to 22.214.171.124, please contact our technical support for information and instructions.
