Description

The SDP created by osmo-sip-connector is invalid:

a=rtpmap:0 GSM/8000

Freeswitch rejects this.

Looks like the MSC is sending 0 for payload_type.
See mncc.c:check_rtp_create() in the sip cxtr

This works with legacy nitb:
You get this line in sip-connector's debug log:

mncc.c:393 RTP cnt leg(5010) ip(172.16.0.15), port(16412) pt(3) ptm(768)

With osmo-msc it will be:
mncc.c:393 RTP cnt leg(5010) ip(172.16.0.15), port(16412) pt(0) ptm(768)

note pt(0)
