Use 12.1(5)Txx, where xx=latest train. Or use 12.2(8)T.

Thank you for the response, but I don't have the bind option when trying
to configure this, I have the following. This is on both routers, one
is running 12.1(12) and the other is running 12.0(7)T. I tried the
interface option, no luck.
r8(config-if)#h323-gateway voip ?
h323-id Specify an H.323 ID for this interface
id Gatekeeper identifier
interface Configure H323 Gateway Voip Interface
tech-prefix Specify a technology prefix
r8(config-if)#h323-gateway voip

~On the loopback interface of each router add the command:
~
~Router(config-if)# h323-gateway voip bind srcaddr <ip_address> ~ ~For
the IP address, use the loopback address. This will take

~I have VOIP set up and working, I have it configured so that the voip
~peer is the other routers loopback address. I was assuming therefore
~that the source and destination addresses of the packets between the 2
~routers would be the loopback addresses that are configured,
~but that is
~not the case. When debugging ip packets, I found that the source and
~destination was actually the IP address of the interface that the
~packets are being forwarded out of and received on. See below, can
~anyone tell me why this happens, and if there is a way to force VOIP
~traffic to use a particular IP address, other than using NAT? If not,
~will the VOIP traffic always be sourced with the IP address of the
~interface on which it leaves? Thanks. ~ ~R7 ~! ~dial-peer voice 2 voip
