The call connects, but media IP in SDP is 127.0.0.1 and some API errors

[shah-hussain-khattak]

Hi Team,

Thanks for the help in issue # 1, I can connect the call. But seeing the media IP negotiated by the server is 127.0.0.1 in the final 200 SDP:

I made some changes in the call.py script, so the media IP stays my server's public IP, the results after that were:

Can you please share some suggestions/ideas on how to fix this? Am I missing something from the configuration point of view?

Thank you!

You should not have to modify the code, you can simply set the IP in the SDP through the rtp_ip setting. If you do it like so, does it have the same behavior?

[shah-hussain-khattak]

Hi Razvan,

I set up the parameters as you mentioned, but for some reason, the SDP is sending 127.0.0.1 IP for media:

These are my settings:

root@ip-172-16-8-193:/usr/src/opensips-ai-voice-connector-ce/docker# more config.ini
[opensips]
ip = 127.0.0.1
port = 8080

[engine]
event_ip = 127.0.0.1
rtp_ip=52.65.xx.xx

[deepgram]
disabled = false

[openai]
disabled = false

root@ip-172-16-8-193:/usr/src/opensips-ai-voice-connector-ce/docker# more .env
DEEPGRAM_API_KEY=
OPENAI_API_KEY=sk-proj-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
MI_IP=127.0.0.1
MI_PORT=8080
root@ip-172-16-8-193:/usr/src/opensips-ai-voice-connector-ce/docker#

root@ip-172-16-8-193:/usr/src/opensips-ai-voice-connector-ce/docker# more docker-compose.yml
services:
engine:
container_name: ai-voice-connector-engine
build:
context: ../
dockerfile: ./docker/Dockerfile
network_mode: host
environment:

opensips:
container_name: ai-voice-connector-opensips
image: opensips/opensips:latest
volumes:
- ../cfg/:/etc/opensips/
network_mode: host

The SDP sent is:

v=0
o=- 3939530862 3939530862 IN IP4 127.0.1.1
s=pjmedia
t=0 0
m=audio 46990 RTP/AVP 8
c=IN IP4 127.0.1.1
a=sendrecv
a=ssrc:2053979861 cname:4fbb0d8b65557ff9
a=rtpmap:8 PCMA/8000

Please advise me, on what I am missing.

Thank you!

For some reason, the config file is not picked up by the engine. There was a fix for this, can you pull the latest source code? If not, try to export the RTP_IP variable in your environment.
