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 CONN: (1701/rtp, id:0x49AD9023, ip:10.40.16.36, rtp:19856 rtcp:19857) Packets Sent: 0 (0 bytes total) Packets Received: 0 (0 bytes total) Timestamp Errs: 0->0 Dropped Packets: 0 Payload Type: 96 Rate: 16000 Channels: 1 Frame Duration: 20 Frame Denominator: 1000 FPP: 0 Packet Duration: 20 FMTP-Extra: (null) Audio-Name: VND.3GPP.IUFP/16000 Sub-Type: VND.3GPP.IUFP Output-Enabled: 1 Force-PTIME: 0 CONN: (1701/rtp, id:0x5AFEDEF8, ip:10.103.36.93, rtp:55078 rtcp:55079) Packets Sent: 918 (15606 bytes total) Packets Received: 1118 (34350 bytes total) Timestamp Errs: 0->0 Dropped Packets: 0 Payload Type: 96 Rate: 16000 Channels: 1 Frame Duration: 20 Frame Denominator: 1000 FPP: 0 Packet Duration: 20 FMTP-Extra: (null) Audio-Name: VND.3GPP.IUFP/16000 Sub-Type: VND.3GPP.IUFP Output-Enabled: 1 Force-PTIME: 0 OsmoMGW#
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 )
