[Asterisk-Users] IAX choppy sound

[Stojan Sljivic - GDS]

Hi,

> Are you using Trunked IAX?
Currently we do not use trunking. 

> How many calls at a time?
All the test we have performed so far were with only one active call.

> What codecs are you using?
We have set the bandwith=low, so I think that G.723.1, GSM, and LPC10 are in
the play.

> What is the ping time between the systems?
Ping stats are:
Server 1:
50 packets transmitted, 50 received, 0% packet loss, time 49491ms
rtt min/avg/max/mdev = 190.198/213.028/283.275/25.307 ms

Server 2:
50 packets transmitted, 49 received, 2% packet loss, time 49523ms
rtt min/avg/max/mdev = 190.089/214.855/544.880/59.052 ms

> Any error messages ?
There are no error messages in the console.
