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

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
)

Hi,
I guess you mean Ericsson HNB, not Ericcson MGW as you wrote in the
email topic.
this is the problem:

IuUP(C6A09234)[0x562a59d9c600]{Initialisation}:

Our IuUP implementation expects RFCI num X to be at position X of the
array (starting from 0). This is a limitation of the current
implementation, which worked well with nano3g HNB so far.
see libosmocore/src/gsm/iuup.c
Patches to improve IuUP support are welcome. Otherwise, if you need
someone to invest some hours into improving this part of the code or any
integration work in general, I kindly remind you that you can contact
sysmocom for commercial support on this kind of topics.

Hi,
Thanks for feedback.
No, I mean Ericsson MGW.
On the Iuh side we have Spidercloud wires Services Node.
The RTP link to Iuh is OK, problem is Osmo MGW - Ericsson Mgw.
But Ok, I'll get in contact with Sysmocom.
Regards,
/Sjur

A small typo there..
" On the Iuh side we have Spidercloud wireless Services Node"
Right should be right😊
