Hi,
I'm using OsmoMGW version 1.9.0.20.069dd.202204110026 and OsmoHNBGW version
1.2.1.13.be9e.202204110026.
Call is established, but is silent.
The connection is up,but only data flowing one way:
OsmoMGW# show mgcp endpoint rtpbridge/1@mgw
Virtual trunk 0 endpoint rtpbridge/1@mgw:

And I can ping 10.40.16.36 with source 10.40.50.67.
But there seems to be aproblem with RTP initialization on link towards core ( Ericsson MGW
)
