[SR-Users] Altering received parameter in Contact

I'm hoping someone can give advice on altering the received parameter in
the Contact header on a reply. The situation is that a customer is
REGISTERing using TLS, and our Kamailio replies with a 200 OK that includes
a Contact header like this:

Contact: <sip:123456789 at xx.xx.102.10

The customer's device apparently had an issue with this, and the device
manufacturer advises that they need the ";transport=TLS" on the received
parameter removed. This sounds like a strange requirement, but it's what
we've been told. Does anyone know how to alter this in a Kamailio

Our system uses www_authorize to authenticate and is running Kamailio 4.2.1.

Thanks in advance for any help!
