Voice Problem.

Hi Guys - Wondering if anyone can help me.

I have a very basic setup, 2 2600s with a an anologe phones on each.
I make a call from R2 to R1 and I see the H.323 setup and the rtp data, just
for an example below.
Thing is, I just get a gabled sound when the call is in progress and I dont
seem to be able to speak over the connection.

Has anyone else had this? Also, on the RTP stream, I get on my 2600 a
source interface of null0 in the packet debug? is this also normal?

Dont pay attension to the source/dest IPs in the decode as I have had to
change them and mucked it up a bit in the output :)

Please could some help.

Many thx
