Cisco router - Block UPDATE/REINVITE message

Hello.

I seem to have a problem with UPDATE messages being generated and this is causing my provider to respond with 481 message "Call Leg/Transaction" does not exist.

For this reason, I have tried disabling UPDATE messages but to no avail. I have managed to remove the field from the INVITE Header using Sip-Profiles, but that only applies to calls I generate.

My question is,is it possible to modify the INVITE Header for incoming calls using sip profiles? Or just blocking reinvites as a service? This is a simple matter which I have not found an answer by browsing the Cisco forums.

Platform is a AS5350XM, IOS version: 15.1
