Michael, It looks like something strange is happening to the SIP traffic between the Cisco and FreeSWITCH. You shouldn't have to force FreeSWITCH to send traffic to a registered user on a specific port, the Contact: header and/or FreeSWITCH NAT handling take care of that for you. Can you show us a siptrace and console output with "sofia profile internal siptrace on" and upload it to pastebin.freeswitch.org? On Wed, Oct 13, 2010 at 9:48 AM, Michael W.

Hi,
I'm using Monday's FreeSWITCH build, with a config originally loaded 19 August 2010. I'm working my way through the FS 1.0.6 book.
I have two phones, one Zoiper soft phone and one Cisco 7960. Both register fine, and the Cisco can call Zoiper. Zoiper cannot call the Cisco, however.
The Cisco phone sends its register requests from UDP port 50790. When FreeSWITCH sends an INVITE to the Cisco, it tries to contact UDP/50790, and the phone returns an ICMP "destination unreachable."
This same phone is also registered to an Asterisk box. When I call that number, asterisk connects to UDP 5060 on this phone. The phone replies from a high-numbered port to 5060.
It seems I need some option to tell FreeSWITCH to send the INVITE to 5060? Or am I missing something?
Thanks, ==ml
