Asterisk can't connect to SIP-Provider after DSL reconnect

mircsicz

Hi all,

I've just got a SIP-Trunk from Sipgate, before that I only had an old private accoount at sipgate. Now that both accounts are configured on my Askozia Box they don't reconnect after my DSL reconnect at 4AM…

First thing I tried was rebooting the Askozia Box, guess what no success...

Then I tried resetting my DSL-Modem, no success again.

Then I rebooted pfSense and both SipGate connection's became available again!!!

Today I had another try, first the log entry from Askozia:


Nov 7 04:01:02 asterisk[1819]: NOTICE[1847]: chan_sip.c:27638 in sip_poke_noanswer: Peer 'SIP-PROVIDER-901827029526f27e0abeda' is now UNREACHABLE! Last qualify: 15

Then I resetted the PF state's table and the connection was immediatly available:

I don't wanna reset my state's table every morning an hope one of you can give me a hint to an automatic solution

As no one replied I do… ???

There's an article about VoIP-Config:
https://doc.pfsense.org/index.php/VoIP_Configuration

Which contains a link to https://doc.pfsense.org/index.php/Static_Port but I don't get it right:

In many cases you must enable advanced outbound NAT and not rewrite the source port on this traffic, such as where multiple phones must connect on a single public IP. To do so you need to not check the static port box.

So could someone please describe a bit more detailed where this setting has to be done?

The only other option I see is installing package "siproxd", but before I do that I'ld like to test the other options recommended in the docs!

seems I was hit by this bug:
https://redmine.pfsense.org/issues/1629

which is also discussed here:
http://forums.askozia.com/index.php?topic=2336.0

I'll try the script mentioned here:
http://forum.pfsense.org/index.php?topic=18053.5

EDIT #1:
I went with the hint from the redmine:

So to fix my issue i had to run this command every time the WAN IP Address changes.

I created this script with info i found in the internet

create /usr/local/bin/reset_states.sh

#!/bin/sh

Kill Udp Sip States after new wan IP

echo "Killing States from ASTERISKIP to SIPPROVIDER" |logger;
/sbin/pfctl -k ASTERISKIP -k SIPPROVIDER

Change file permissions

chmod 755 /usr/local/bin/reset_states.sh
Edit config file /conf/config.xml

<system>…
<afterfilterchangeshellcmd>/usr/local/bin/reset_states.sh</afterfilterchangeshellcmd></system>

And if I've success report with a last self-reply…

EDIT #2:
Half successfull, inbound is fine with the script, but outbound is still not working:
