[Asterisk-Users] IAX Bandwidth Question

[WipeOut .]

I have 2 asterisk systems connected by a 56kbps internet dialup (so at best 33.6k in both directions) using IAX and GSM...

The one * box is at my home and the other is in the office (before anyone freaks this is a test environment)... Provided nothing is using the line at the same time I am able to carry 1 voice call over the dialup link with no real latency.. Ping times when no call is in session are about 165-175ms and when a call is active 190-240ms.. I just ran a call for 5 mins to see if the ping time climbed as you are experiencing and it didn't increase at all..

So you may have some other issue causing the increase in ping times..

Sorry I probably wasn't much help..
