Hello,
I've setup a ser proxy/registrar which forwards PSTN calls to an AS5350. The AS5350 also redirects PSTN calls to the ser box, which associates incoming called numbers with sip accounts through associations in the SQL DB.
My problem is that the AS doesn't know about these associations when forwarding calls from sip to PSTN. I'd like to set the callerid on the outgoing calls to be the PSTN number associated with the sip account for incoming calls.
thanks
