Hello Jenkins Builder,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/4905
to look at the new patch set (#2).
libosmo-mgcp: Connection Identifiers are allocated by MGW, not CA
The MGCP connection identifier is allocated by the MGW while processing
the CRCX, see RFC3435 2.1.3.2:. Including/Accepting a connection
identifier in CRCX is "forbidden" as per RFC3435 Section 3.2.2.
So the MGW side must *reject* a CRCX message with 'I' parameter, and
allocate a connection identifier which is subsequently returned in the
response.
Closes: OS#2648
