Hi men, I have already encountered some issue like this with few switches (very known great brand) which doesn't like VoIP traffic ! 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. You can also tell to "qualify" with a longer delay, but this could not help in case of regulary frames losses. Good luck ! Francois BERGERET, France.

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.

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 Regards Ing.
