Hello, I am not sure so you should test contact_alias function on lab , if you can. First ,set contact alias and remove received parameters from contact header. on reply , use handle contact alias. Kamailio care alias to find right transport protocol. http://kamailio.org/docs/modules/5.2.x/modules/nathelper.html#nathelper.set_contact_alias
Good luck.

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:[email protected]:5061;transport=tls>;expires=3600;received="sip:xx.xx.102.10:36051;transport=TLS" 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 configuration? Our system uses www_authorize to authenticate and is running Kamailio 4.2.1.
