sip: Specify invite contact tag
Version 1.12.12 of libsofia-sip-ua no longer automatically generates a contact header element from the local ip address and port. Specifying the contact tag does not break operation with the existing library (1.12.11), but allows for operation on a system with freeswitch 1.10.4 or later installed, which is built against this new version of libsofia-sip-ua.
