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

[Daniel Grotti]

Hi,
Rtpengine does not provide any transcoding between codecs. 
Anyway, speaking about your issue looks like you are calling from pstn a nn local subscriber so the call dies in ngcp unless you enable the peer_relay in the config.yml.

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.
