Hi All,
I followed instructions on this Obi forums and FreePBX site to configure Obi110 as a gateway to GoogleVoice and PSTN on my Asterisk setup. Everything works fine including incoming/outgoing calls with caller id through PSTN and Google Voice channels. But sound quality on outgoing PSTN calls is very bad; voice is mumbled and it breaks quite often. Voice quality is very good on outgoing calls through GoogleVoice. So I assume it is something to do with the Obi110 configuration.
Do you have any suggestions to fix this? Any help is appreciated.
Thanks.
Update: Voice quality seems to be fine now. I have a different issue which I did not notice earlier. For incoming calls through PSTN, Asterisk does not show the Caller ID. Instead it shows the trunk name (username) I used for Obi110 SP2 SIP registration. But for calls coming through Obi110's Google Voice channel, the caller id is displayed correctly.
Google Voice caller id started showing up after I enabled X_SpoofCallerID on ITSP Profile A, but I don't see a similar option for Physical Phone Line.
Do you any option to get caller id working in this case?
Analog phones connected to PSTN line displays caller id correctly.
thanks
