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