Recently, we purchased a new ASUS RT-AC3200 router and I am having trouble configuring my OBi202 device. The OBi202 is in the DMZ zone of the router, therefore there are no port forwarding issues. Furthermore, I have disabled SIP Passthrough.
I have 2 Phonepower accounts and 1 GoogleVoice account on SP1, SP2, and SP3 respectfully. The first Phonepower account and the GoogleVoice account register successfully ("Registered" and "Connected" status messages). However, the second Phonepower account refuses to register and I always get a "No Reponse from Server" error message.
With the previous router, we had this problem with the Phonepower accounts as well, and to fix it we changed the X_UserAgentPort setting on the second account to port 5061. The first Phonepower account has X_UserAgentPort set to 5060.
If I put back the old router, both Phonepower accounts "Register" successfully - very strange. Therefore, it seems like this is not an OBi202 configuration issue, but yet I can't think of anything else to change in the ASUS router since the OBi202 is in the DMZ and SIP passthrough is disabled. Also, if it were a router problem, I would expect *both* Phonepower accounts to fail to register, but the first one is successful.
Does Phonepower have to change something on their end to allow the second account to register?
I'm out of ideas for configuring the OBi202 or the ASUS router. Any help is appreciated. Thank you.
