hi guys, I have 1-way audio..far end can't hear me....connection: US to UK, over public ip.....my end/US..cisco 2811....>cisco switch2900...>FW(ASA)...>internet, codec g711ulaw on both ends...UK side:internet....>soft switch (Veraz)...any ideas what may be causing this 1-way audio problem...I have a simple config on my 2811, no QoS/CoS yet........
The farend told me today that they do not see that we are sending rtp msgs...
Thanks in Advance,
Have you tried changing the codec to g729, 711 requires a lot of overhead and bandwidth and typically run onnet in the office. I assume this is CME?
Is it between offices or between specific devices? Periodic?
I have not tried that yet, I will try....it is between offices..network setup...voice server (with dialogic t1 card)---->2811--->cisco 2900--->FW (ASA--->internet...
The farend is saying I am not sending rtp packet/msg..
note: I have the 2811 bandwidth for myself.it is just one test call i place over it.
So the call set's up, rings the far end, the far end goes off hook, but no audio? This may be a stupid question, but are they answering via headset, speakerphone, or handset? Do you know that you have a known good phone?
yes they pickup the phone (a desk phone)no speaker or headset)and say hello, i hear them,but when I hello back to them they do not hear me.
it is wide..have tried other phone set and other phone #'s...
How about the farend telling me they do not see I am sending rtp packets/msgs

Something like this access-list 100 permit ip 192.0.0.0 0.255.255.255 host 192.x.x.x(going to fa0/0)...that seemed to be dropping rtp/udp packets
