Audio delay on incoming leg

[timerider]

Bit strange because it only 'seems' to happen on some calls, but I get a gradual increasing delay from the leg coming in, to the point where some calls it's 10+ seconds behind... I've tried everything I can think of on this side, attempted to turn off jutter buffer etc but still it remains. There also could be a delay in audio getting to the remote callee.

Anything I can try or that you've come across before? Server hardly touching the CPU/RAM and drive is an SSD (though in a datacentre).

Thanks

Yeh, usually the codecs ptimes are mismatched. Usually only see problems on janky endpoints like the Cisco SPAs.

If you haven't already, try making the endpoints and the PBX only use PCMA/PCMU and see if the problem remains, if it's gone then you know it's probably a codec issue.

Good chance you're right on that, forget to mention it 'appears' to only happen on some endpoints. I've set up things to U/A already but yet to properly test. Massive delays though, where is storing that buffer I dunno!

I'll post back with my findings.
