[Spce-user] Rings once, then disconnects!

[Andreas Granig]

Hi William,

Maybe your peering partner doesn't like the SDP body (specifically the
list of codecs) or something.

Try to limit the list of codecs on your 3CX to G711 as a start. Maybe
also the SIP message (the 500 from your carrier) contains a header
providing more details. From a SIP signaling perspective, there is a
B2BUA in the SPCE, so the outbound message should be *somewhat* equal
all the time no matter what client you're using, but then again the SDP
is passed through more or less as-is, which could be a starting point
for trouble-shooting.

Anyways, your carrier should be able to explain the reason why they're
sending a 500 reply.
