Problems with dialing other 323 systems

We have had issues where we can dial one way via H.323, but not the other way...here is the topo:

CodecA---Cat2948--Cat6509--PiX---7513--ATM--3810--PIX--CAT5000---codecB

Can initiate a call from b to a but not from a to b...any ideas?

Re: Problems with dialing other 323 systems

This sounds like an issue with one or the other firewall. Are they 323 enabled? If so, have you opened port 1720 to allow RAS traffic to pass? Couple of ideas...

Re: Problems with dialing other 323 systems

Do 3810s that are doing PAT have a problem passing H.323 traffic. We have since resolved the previous scenario, but are now dealing with this scenario....

A-non-ciscoswitch-MC3810-ATM-7513-PIX-6509-2948-B

A can dial B, but B cannot dial A...We are doing PAT on the 3810, with the codec A having a static translation...Any help will be greatly appreciated
