Dear list,
Hi.
I watched Neel's OsmoDevCall presentation on this topic, but it is not
very clear what codecs are supported when osmo-sip-connector and an
external PBX is used?
The question is somewhat out of scope for this list. The answer to what
codecs are supported with an external PBX is it totally depends on the
external PBX.
run sngrep on the interface carrying the SIP between your PBX and
osmo-sip-connector and take note of how your PBX is responding to the
INVITE.
If the external PBX is supporting AMR, at least in pass through mode,
that should be all you need for a mobile to mobile call. For "external"
SIP calls, well it totally depends on what your external SIP EP is
supporting and so therefore whether or not your PBX needs to do
transcoding, and if it does, then you need that capability, (obviously),
and I would tend very strongly to assume you don't have that
out-of-the-box with Asterisk.
