Experts,
I am not sure if this is the right list for voip as well, if not can you
please advise a nice list/group where I can post it?

Anyway I have setup a very simple voip gateway on my cisco 2621 running
c2600-is-mz.123-26.bin with c2600-is-mz.123-26.bin and attached to the
internet via the FE interfaces.

People can call me on the public interface and all works fine: my pots rings
and we can talk....

1) how can I force a certain type of codec?
2) when i do: 'debug voice rtcp' what I see in the lost packet is: how many
packets that my interlocutor has missed out of my RTP stream?
3) if there is a working call setup between A and B and on A I type:

A#show voice dsp

DSP DSP DSPWARE CURR BOOT PAK TX/RX
TYPE NUM CH CODEC VERSION STATE STATE RST AI VOICEPORT TS ABORT PACK
COUNT
==== === == ======== ======= ===== ======= === == ========= == =====
============
C542 001 01 gsmfr 4.1.46 busy idle 0 0 1/0/0 NA 0
22844/80407

the codec gsmfr is from A to B or from B to A? Or the codec is always the same
for the two directions of the calls?

Thanks,
Bit.
