Are you sure you are using the configuration files from this repository?? Also, which kamailio version are you using??

[herlesupreeth]

Please disable the IPSec encryption so that I can debug easily.

Are you sure you are using the configuration files from this repository?? Also, which kamailio version are you using??

version: kamailio 6.0.0-dev2 (x86_64/linux) 0da3eb Kamailio_IMS_Config :5.3 version

[herlesupreeth]

You have to use the configuration files from the master branch and not 5.3 branch in Kamailio_IMS_Config repo

When i am trying to enable video call, it is enabling but after 10sec it is disconnecting. vc_disconnect.zip

@YokeshwaranM2002 I would suggest retaking the pcap for the following scenario since you have attempted too many calls and hard to debug:

1. Deregister all UEs
2. Start pcap
3. Attach UEs
4. Attempt calling
5. Enable video call
6. Wait for it to fail
7. Stop the pcap

Attach above obtained pcap

sec_time_call_not_established.zip Some times when i am trying to call, the call was not established..Sometimes i am getting error as session interval is too small.

[herlesupreeth]

Thanks for pcap. In the pcap I see that Redmi is not supporting upgrading audio call to video call

[herlesupreeth]

Sometimes i am getting error as session interval is too small

For this usually UE updates the session interval time based on the response from other UE but I dont see your Motorola updating the request. Sadly its not upto the IMS to do anything here and upto UE SIP client implementation
