Hi men,
I have already encountered some issue like this with few switches (very
known great brand) which doesn't like VoIP traffic !
I also have switches of a very known great brand !!
It was so strange to me that I didn't consider a network problem...
Check by drectly connected the VoIP equipment - if you can - with
temporary long Ethernet cables bypassing the tested switch to see what
happens in this case.
I'd try to bypass the switch someway but every server neeeds to have its
own public ip address..
I'll put an RTP proxy somewhere...
You can also tell to "qualify" with a longer delay, but this could not
help in case of regulary frames losses.
What about turning qualify off ?
Do you think taht Asterisk is stopping RTP when it loose a qualify packet ?
Or is the RTP traffic itself that is lost by the switches ?
Good luck !
It couldn't be more appropriate...
Tnx for help ;)

Well, we have add similar issues - do you use a media gateway /.IP
Phones / softphones as your extensions?
We were running Audiocodes and for some reason (I suspect a poor
ethernet switch), when there are more than 15 people using the line,
Audiocodes will not respond to a qualify and asterisk will drop the
call. Turned off qualify (removed qualify=yes) and <still keeping
fingers crossed> things seem fine.

Hi all,
I'm having a problem with some Asterisk servers
interconnected with
each other using IAX (I also tried with SIP without solving the
problem)
Sometimes, with apparently no reason, some peers become UNREACHABLE
(I have qualify=yes in iax.conf) and REACHABLE again as soon as
another qualify test is made.
Our users are also complaining about audio loss during their calls,
apparently randomly, everything goes ok for days and bad for
another few
days.
I strongly believe the 2 problems are strictly related because
in the
logs I see REACHABLE / UNREACHABLE messages only for certains days
without regularity.
The days in wich i see a lot of messages are exactly the days with
most of complaint about audio loss
I just noticed that timestamps of the logs (REACHABLE / UNREACHABLE)
are quite always during business hours, this makes me think at
somewhat
related to load (cpu load, badwidth load, calls load, etc...)
But, looking at hardware specs of our lan, servers and average
load I
don't think they are over-stressed.
Our servers are all:
2 x Intel(R) Xeon(TM) CPU 3.20GHz
1 GB RAM
2 x IDE HDDs Software RAID 1
Asterisk 1.2.13 with res_perl
Gentoo Linux
Some of them has a Sangoma card connected with an E1
Most ot these are on the same LAN, interconnected with a 1 GB switch
(I don't think it should be a bandwidth problem).
Load averages of these server is varying from 0.5 to 1.0
(I guess it should be ok)
On each server we don't have more than 50 concurrent calls
(bridged SIP <-> IAX2 or IAX2 <-> ZAP)
Used codec is mostly G729
Sometimes on asterisk cli i see some messages like
"Avoided initial deadlock for '0x9fd130', 10 retries!"
I don't know if it could be somehow related.
Someone of you can point me in the right direction ?
Tnx in advance
