ubr924 - disregard cable

Hi,

Having the alternative to test routes with the ubr924 sounds good, I don't
need to use the cable interface, I just need to connect the router to the
network and be able to place test calls over the internet to another
gateway.

The scenario will be simple: gateway - gateway , no gatekeeper present,
question is, does the cable router needs a public IP or private ok?
currently i have it inside the network but it's odd i don't get a dial tone,
when i try to dial from the far end into the gateway here the phone rings
ok. I have forwarded port 1719:1720 to the cable router.

Any advice creatly appreciated,

Allen

I've tried this on two ubrs. One of them died ugly death (memory failure),
second turned out to have defective DSP and voice ports were simply not
functioning. But yes, it's doable. H323 may not like NAT, however. Here's my
sample config:

voice class codec 1
codec preference 1 g723r53
codec preference 2 g723r63
codec preference 3 g729r8
codec preference 4 g726r16
codec preference 5 g726r32
codec preference 6 g728
codec preference 7 g711alaw
