We had to remove ALG on our fwall rules.  It's been a while now, but I think it 
resolved the symptom you are having.

Er, uh...

I think I called you with my pfsense last week via ISN, I am using pfsense 2.0, 
so that went on for more than 5 minutes.

inbound seems fine.
I'll play in the office some.  was hoping to send keepaliaves on tcp port 5060 
to the far end, tshark port 5080 or 5060 didn't show ANYTHING while call was 
active.



I think you need to find someone with a firewall OTHER THAN those listed and 
see if they will let you call for more than 5 minutes. Last I heard Nathaniel 
is also running pfsense (but I think not 2.0).

I have other sites I can log into with a softphone but they all front pfsense, 
so I am afraid I might be of no use to you in this instance.

I think it might be something to do with how the remote firewall ACK's the call 
and drops it after 5 minutes because it cannot tell it is established. It might 
not be anything to do with keepalive, but an ignorant signalling 
interpretation, but don't take my word for it.
I suspect that is what it is.  I also can't (reliability) forward calls from 
them.
