Review request for Asterisk Developers and Kevin Fleming.


Summary
-------

after storing the route header for an update request in a early dialog (for example 180) i have found that some phones didnt sent a contact header in a 1xx response. Without this contact header we couldnt sent out an update request.

this small change checks if we have an okcontacturi and didnt sent out the update request if not.

Testing
-------

test it with a cisco spa941 which didnt sent a contact header in 100 or 180 and with a cisco spa525 which sent out a contact header.

normal connected line updates work as expected.


Thanks,

schmidts
