BIB recording with TLS, CUCM send BYE immediately after ACK

crystalrs
Level 1
Level 1

Hi guys,

We have a BIB recording system, and it works fine without TLS supported.

But now we are facing a problem while supporting TLS.

We already setup certificate and SIP trunk with TLS and CUCM and recording have exchange SIP message successfully.

The question is:

After CUCM:INVITE, recorder:200, CUCM:ACK, CUCM send a BYE immediately.

Following is the follow for an example:

INVITE sip:7777@192.168.1.68:5061 SIP/2.0
