Basically, I'm trying to get Asterisk to send all future INVITEs to
Kamailio on port 5060 and not the source port of the REGISTER.  My REGISTER
looks like this:

U 1.1.1.1:59738 -> 2.2.2.2:5060
REGISTER sip:2.2.2.2:5060 SIP/2.0.
Via: SIP/2.0/UDP 1.1.1.1:5060;branch=z9hG4bK404.05c2e5a7.0.
Via: SIP/2.0/UDP 3.3.3.3:10654
;rport=56417;branch=z9hG4bK-d8754z-a5ad572f022375cb-1---d8754z-.
Max-Forwards: 16.
To: <sip:sip7878_spqa at 2.2.2.2>.
From: <sip:sip7878_spqa at 2.2.2.2>;tag=d8932554.
Call-ID: OWU3NDM5N2MxOTVkOTM5YjE4MjZkMDFjYWIyN2JlNjI..
CSeq: 2 REGISTER.
Allow: INVITE, ACK, CANCEL, BYE, NOTIFY, REFER, MESSAGE, OPTIONS, INFO,
SUBSCRIBE.
Supported: replaces, norefersub, extended-refer, timer, X-cisco-serviceuri.
User-Agent: Z 3.3.21933 r21903.
Allow-Events: presence, kpml.
Content-Length: 0.
Path: <sip:3.3.3.3:56417;lr>.
Contact: <sip:sip7878_spqa at 1.1.1.1:5060>.
Expires: 3600.
.

Subsequant INVITEs are sent to 1.1.1.1:59738 and not 1.1.1.1:5060.  I need
them to go to 1.1.1.1:5060.
