[Freeswitch-users] No response to registration requests with high port numbers?

[Alex Lake]

Hi,

Got a problem with a handset that doesn't seem to be registering on our 
Freeswitch server. The diagnostics from a member of Cisco support said...

"At packet 422 we see the phone "0_4147057716 at 192.168.40.26" send a 
registration request to 5.9.36.113:5060 from 175.159.77.82:32060 - We do 
not see a reply to this from the SIP provider.

We responses to requests from 0_359240637 at 192.168.40.26 
<mailto:0_359240637 at 192.168.40.26> with source port 5060, which suggests 
to me that the SIP provider is not replying to the high UDP port 
requests. As the MX is a NAT device, subsequent SIP requests will always 
have a high UDP port."

I'm not sure where we might configure acceptable ranges of SIP source or 
if it's something else.

Thanks for any suggestions...

Alex
