we have no filters like that, sounds like a network path issue. /b On Thu, Jan 11, 2018 at 9:47 AM, Alex Lake <alex@digitalmail.com> wrote:
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@192.168.40.26" <0_4147057716@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@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
