[Asterisk-Users] Funny thing with LinkSys / IAX2

[Andrew Edmond]

*Community,
 
I am a new VoicePulse customer, using their EXCELLENT
connect.voicepulse.com services.  
 
I have asterisk CVS head 10/20/04 running quite successfully, with 10
SIP phones, voicemail, and 2 zaptel lines.  The box is running Gentoo
Linux, and is running on an Internet connection which is a ComCast cable
modem, with a LinkSys BEFSR41 router running the LAN.
 
I have IAX2 configured in IAX.conf registering my IAX2 line with their
gateway.  My toll outgoing calls are routed through their IAX2 gateway
(my local calls go out through my Zap lines).
 
However, I'm constantly having to "restart now" on the CLI (about every
ten-thirty minutes) to keep my connection to VoicePulse online (incoming
AND outgoing calls).  I have port forwarding on for ports 5060 and 4569
to my asterisk box.
 
After talking with user VoicePulse in #asterisk, we think that it has to
be something with the router or Internet connection we have.  Something
about routing or NAT tables being unreliable in LinkSys routers.
 
Anybody have any IAX2 weirdness with ComCast or LinkSys routers or a
combination of the two?
 
Help!  Thanks!
 
Andrew
