[Asterisk-Users] SIP to H323 with no joy

[James Hartman]

Greetings and salutations to all...

I'm having a bit of a problem getting a SIP phone (Xten) to call an H323 Cisco ATA-186.  Both devices can call into the * and get the demo, voicemail, etc...  I'm pretty sure my problem is in my configs as it feels like a stupid error and to prove this to myself I set tcpdump on the * box to capture all UDP traffic going to and from the ATA-186.  If I call the * box from the ATA tcpdump sees all.  When I try to call the ATA from the SIP phone tcpdump sees nothing at all and my SIP phone times out.  I also ran a port scan on the ATA to make sure everything on it is as it should be.  

Believe me, I wish I could use SIP for everything but I have no choice in the matter and upper management doesn't listen to reason (imagine that) so this is what I'm forced to deal with.

I'm sure it's a stupid mistake on my part.  I just need someone to hit me with the cluebat and open my eyes a little.
