Dear experts
We try to configure osmo-bsc / osmo-mgw to be able to communicate with ERICSSON MSC/MGW.
The UE is well registered but we don't know how to well configure bsc.
We have this config file osmo-bsc.cfg:
- 172.20.10.10 is a local BSC address to communicate to STP, MSC, MGW
osmo-bsc
mgw 0
local-ip 172.20.10.10
local-port 2427
remote-ip 172.20.10.10
remote-port 2727
reset-endpoint rtpbridge/*
We have on the BSC a local mgw, and here is the osmo-mgw.cfg file:
172.20.10.19 is another address on the BSC towards the osmo-bts-trx.
osmo-mgw
mgcp
domain mgw
bind ip 172.20.10.10
bind port 2727
rtp port-range 4002 16001
rtp bind-ip 172.20.10.19
rtp ip-probing
rtp ip-dscp 0
rtp keep-alive once
rtcp-omit
rtp-patch ssrc
rtp-patch timestamp
no rtp-patch rfc5993hr
sdp audio-payload send-ptime
sdp audio-payload send-name
number endpoints 512
osmux off
Sure we made errors and misunderstood.
During test call, we can see in the trace, a Call proceeding, then a BSSMAP Assignment
Request followed by a BSSMAP Assignment Complete.
The problem is that the IP choosen as AoIP Transport Layer Address is the OAM address of
the BSC (seen in In GSM A-I/F BSSMAP Assignment Complete trace section - UDP port 4004).
How to change this in order to set 172.20.10.10 as the AoIP Transport Layer Address ?
Many thanks in advance,
best regards
Jean-Marc
