H.245 missing packet

Hi All,

We have a problem when integrating Meeting place IP Gateway in DMZ area with Voice Gateway in Internal Area

through Gatekeeper. The problem is we can not hear voice from meeting place when we dial in to meeting place

or meeting place dial out to voice gateway (Condition phone can ring and session can establish). After we

capture all packet with ethereal we found some missing h.245 packet after admission session complete. Can

somebody please help me to fix this problem ?? Firewall using cisco PIX firewall version 6.3(3).

Thanks

Re: H.245 missing packet

1. Make sure both sides use "fast-start" (where H245 is encapsulated inside H225).

2. Configure protocol fixup for H225 on the Cisco PIX.
