I am searching for a solution to alter a SDP header to not send video capabilities to a SIP trunk provided by an ISP. The reason is that calls from a Cisco Jabber softphone fails for outbound calls, I receive a "media not acceptable here": inbound works fine.
Cisco Jabber => CUCM => SIP TRUNK => CUBE => ISP SIP TRUNK
Settiing up calls inbound works fine, using a cisco hardware phone (with no video capabilities) works fine for outbound calls. According to the ISP they do not allow that there is video capabilities in the SDP header!!!???? I want to make the ISP ignoring these SDP settings but that seems for them to be difficult. So, question is, can i remove the capabilities in the SDP header on the CUBE and if; how is that possible?

Yah, you're right. Good point of view.
But in my country we usually don't use video at all. And we usually have problems with the carriers because that. So the faster solution is to remove it directaly from devices.
But the best manner to workaround it, is certanly forcing audio to the dial-peers as you sugest, and leave the video capabilities to others options.
We already have here many options and workarounds depending what is better for each cenarium and the needs of each situation.
Good work. Congratulations to everyone!
