[Spce-user] SPCE as an SBC between proxy and trunk

Sat Mar 21 13:25:53 EDT 2015

Hello Daniel,

Thanks for your prompt response, and that too over the weekend.
Rtpengine is not the problem; in fact I have that setup working. With transcoding, I was only referring to encoding RTP traffic to SRTP, which I’ve verified to work as expected in a non-peering setup.

I went ahead and enabled that setting in config.yml, and restarted services with `ngcpcfg apply`

It appears from the logs (pasted here after redacting real hostnames and IPs), that the peering rules are indeed recognized, but the request keeps getting forwarded back into the proxy again and again, rather than onward to a peer.

Am I missing something obvious?

In most cases, the call gets routed inwards, but never onward to a peer. I’m not quite sure if I do at all need to set up (A) a domain, and (B) subscribers, since all I’m really trying to do is set transcoding rules between 2 SIP peers.

The trouble seems to be that no calls never leave the kamailio proxy, with something to the tune of “Callee is not local” followed by "Call to unknown local user from unauthenticated foreign domain.” Really, I don’t need or want any users (i.e. subscribers) at all.
