Problem 200 OK SDP with CON

1. General

Hello Support,

We are facing a scenario in Telcobridges Version: 3.3.13.151. When making an outgoing call, we observed two situations:

When we receive a 200 OK SDP with ISUP ANM, audio is established.

However, when we receive a 200 OK SDP with CON, audio is not established.

Is there any adjustment that can be made in the SBC?

ISUP is not supported on SBC, so you must be talking about TMG units?
ISUP CON should be supported normally.
Please open a case here: https://telcobridges.odoo.com/
We will need a TBreport and the signaling traces.

Hello, thank you for your reply.

The NAP scenario is SIP-I.

In any case, I have triggered the link below.

Thank you.
