Hello Patrick.

I have a SPA8800 connected to two PSTN lines and two analog phones and all of them register as trunks and extensions on a asterisk server, where many other IP phones also connect. The SPA works as a gateway between the internal VoIP phones and the PSTN.

Last year, there was a power failure and we still could make and receive calls to and from the PSTN. The idea of the two analog phones was to provide communications when out of VoIP.

However, when the sip proxy is unreachable (on the same LAN, but out of service), I noticed that I can make calls from the analog phones to the pstn (Auto PSTN fallback set to YES). However, on the same circunstance, incoming calls do not ring on the analog phones.

How can I configure the box in order to make incoming PSTN calls answered by the associated analog phone when the sip proxy is unavailable?

Thanks. Regards,

Fernando

Hi Patrick.

Im new here.

Right now i just set up my IP PBX using AsteriskNOW.

Can you help me how to configure my PBX to make call to PSTN from IP Phone.

Thos is forum related to Cisco products, not the Asterisk. So it would be better you will ask elswhere - if I remember correctly, there are comunity forums on AsteriskNOW vendor site. Even in the case you have a question related to a Cisco product, you should start new discussion, not to comment existing document with question unrelated to it.

Thank you.
