Still Problems with VOIP Registration and old states

pfsense 2.0 on wrap board
static IP-Address (no forced reconnects)

Every 1 or 2 days our Asterisk Server is losing connection to our voip-provider. After googling for sometime I found some hints, about the necessity to delete old state tables. Reseting the state tables manually (Diagnostics|Reset state] works, but is there no way of getting this done periodically?

I tried


/conf/config.xml:
(...)
<afterfilterchangeshellcmd>/usr/local/bin/reset_states.sh</afterfilterchangeshellcmd>

/usr/local/bin/reset_states.sh:
#!/bin/sh
sleep 70
/sbin/pfctl -F state
sleep 40
/sbin/pfctl -F state

but that does not work (Firewall hangs after restart).

Is there really no actually working solution?

I have an issue where my pbx sits on the LAN and although it stays registered with the voip provider, incoming calls via the voip provider are dropped after a few seconds. The symptoms aren't identical to yours, but the fix of reseting firewall states is the same.

Have you tried setting your state table optimization to conservative? I have been resistant to try this because the large numbers of LAN clients here really drives up the states count, but nothing else I've tried so far has worked.

Hi I had a problem where I would loose registration if the internet pppoe session dropped, setting outbound NAT with static port for your PBX solved this I also have a script monitoring my provider registrations and if it fails it sends out an email every five minutes via a cron job until the trunk has re registered.

Would you mind explaining what you did exactly? There are a lot of options there ;)

Interface VoIP Server Static Port

Create a rule the same as above just change your IP address to your Asterisk Box
