Re: [asterisk-users] crossed channels

Ist one channel significant louder than the other? Maybe it is some sort 
of crosstalking. Take a look here:

Hi,

I have installed Asterisk 1.6.2.17-rc2 and I have a strange 
behavior, because sometimes they are crossing channels, thus 
producing unwanted calls connections...Any suggestions?

I've seen this with one of our sip-trunks. Our provider used opensips
for that platform I think. If had the same account registered in two
asterisk-servers and they answered the call at the same time, audio was
from both asterisk-servers and the phone from pstn, like a 3-way conference.

I also watched a presentation about rtp ports, mentioned on this list
some time ago, explaining quite a bit on rtp ports and security:
http://lists.digium.com/pipermail/asterisk-users/2013-January/277342.html
http://media.ccc.de/browse/congress/2010/27c3-4193-en-having_fun_with_rtp.html

So my guess is that if you get two devices using the same port, or one
device that don't stop sending, you will hear that injected in your call.

It can happen with analog dahdi calls.  If this is the case, start 
inbound on one end of the group, outbound from the other end.

We've had similar occurrences with our setup with Asterisk 1.4.44, but I 
have never been able to find out if it was caused by Asterisk or our 
provider. We have never had any problems, then multiple crossed channels 
every day for two weeks, and then no more, so I suspect it was'nt caused by 
Asterisk.


Best regards,

Roel
