Fellow freePBX’ers,
I have a freePBX box setup behind a pfSense firewall. The pfSense has a direct pubic IP (straight Motorola modem). No double NAT.
So for my freePBX settings I chose Static IP and entered when chose auto configure it places the public IP and the local network. Then save.
With this configuration when a call comes in it times out with:
[Mar 8 13:12:44] WARNING[3662] chan_sip.c: Retransmission timeout reached on transmission [email protected] for seqno 4736 (Critical Response) – See https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions
Packet timed out after 32001ms with no response
My router is set correctly with 5060 and 10000-20000 UDP forwarded to my internal freepbx.
The strange thing is that when I set the sip settings to “Public” instead of Static of Dynamic then all calls work correctly.
Does anyone have any idea what is going on?
Thanks,
Mike
