I'm assuming your talking SIP here.<BR>
<BR>
It's not the Contact header that is important here but the Via header. <BR>
Responses should be going back to whatever port is specified there.<BR>
<BR>
Contact header is used for incoming requests.<BR>
Via header is used for responses to outgoing requests.<BR>
<BR>
7965:<BR>
10.1.1.1:44392 -> register (Via: SIP/2.0/UDP 10.1.1.1:5060;branch=xxxx) -> asterisk<BR>
<BR>
asterisk should send a response back to 10.1.1.1:5060<BR>
<BR>
from asterisk cli, run 'sip set debug' and post a copy of the REGISTER and asterisk's response.<BR>

Subject: [asterisk-users] Registering a Cisco 7965 on 1.4.26<BR>
<BR>
Hi,<BR>
I'm having a problem trying to get a Cisco 7965 phone registered on<BR>
Asterisk 1.4.26.<BR>
As we know, Cisco now, for security reasons, has made the phone ports<BR>
non-symmetric, in that it sends out UDP requests on a high port and<BR>
receives them on a different port.<BR>
It seems that, even with 'nat' set to 'no', that Asterisk is not<BR>
honoring the Contact header and keeps attempting to send requests back<BR>
to the high port number.<BR>
I tried this on 1.6.0.9 with nat=no and everything works fine.<BR>
Is this a problem with 1.4.26? Is there a 1.4.x version that works? Or<BR>
did I manage to screw something up?<BR>
<BR>
Thanks.<BR>
<BR>
