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:

   Availability: available

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 )
