I have ser running as a SIP proxy for SIP to SIP calls, and use digest authentication with MySQL for users. I'd like to add the ability for users to place calls to the PSTN through a switch that needs user authentication for PSTN invite requests. I have the same users set up in SER and on the switch, and if an invite request is made to SER for a PSTN number, I rewrite the host and t_relay it to the switch. My question is as follows: is SER able to forward user authentication info to the switch with the invite request? It's not obvious to me if or how this can be done...
