Hello Jenkins Builder,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/6260
to look at the new patch set (#2).
protocol: prohibit wildcarded requests for MDCX and DLCX
When a wildcarded request is made with a DLCX or MDCX command
the MGW will search for a free endpoint and continues the command
execution with that endpoint.
- Catch the wildcarded request early on DLCX and MDCX and return
with an error code.
See also TTCN3 testcases:
MGCP_Test.TC_mdcx_wildcarded
MGCP_Test.TC_dlcx_wildcarded
