Hello,
We are configuring SIP Trunk between our CUCM and OpenSIPS server. As per our study we need to do following activity at CUCM end -
1 - Configure CUCM in Mixed Mode using Cisco CTL Client or using CLI Command
1.1 - Set Enterprise Parameter Security mode as 1. 0 for non-secure, 1 for secure
2 - Configure SIP Trunk Security Profile with TLS
3 - Configure SIP Trunk and assign above SIP Trunk Security Profile
4 - Enable SRTP checkbox in SIP Trunk Configuration
5 - Upload OpenSIPS certificate in CUCM
6 - Upload Call Manager certificate in OpenSIPS
7 - Check lock on Cisco IP Phone after establishment of call
8 - Check OpenSIPS logs for SRTP
Can you please suggest if we need to do additional thing and if forum can point to any specific document for this?
Thanks & Regards,
Umesh
