Hello All.
One of our client is hitting this BUG.
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCuv36964
Problem Description:
The error message occures when CUBE/GW does not understand media attribute like "a=test", so the CUBE when processing the call cannot understand what this attribute is used for, but it will only parse and print the message and ignore.
This error message is only for informative purpose and will not cause any harm to the functionality.
But irrespective of any debugs enabled or not, this Message keeps printing on the router console.
I believe the video SDP within the SIP invite is causing the errors on the CUBE. SIP: Trying to parse unsupported attribute at media level.
I would like to remove or modify the the Video SDP parameters on the below SDP. Highlighted on bold.

I have created the below SIP profile and tested on Cisco's SIP-Profile Tester but unable to remove or modify the Video SDP parameters.

Have also tried.

Any assistance is greatly appreciated.
