[*] Garbled Outbound Audio

[Bergen, Mark]

Thank you for the response Roland;
We are bypassing the router, but we hadn't thought about it possibly being a problem with the PRI itself.
Oh, troubleshooting can be a pain in the butt :).

You might want to try a different router or check your physical MTS lines. In some cases, if your physical line has problems, the router chokes and needs a couple of milliseconds to compensate hence an send/receive error occurs and retries occur. Check your router error messages (clear it first or take note of the first occurrence of the send/receive retries, and then check the time when the garbled audio occurred)

[*] Garbled Outbound Audio







We have noticed on occasion the outbound audio on our phone system is garbled. We have checked the network and it seems to be in good order. It happens randomly and usually only for a few seconds (just long enough to annoy users). It has also happened when there was only a light load on the network.
We configured one of the snom 320 handsets to only use the G711u codec and no real change (outbound audio was still garbled a couple of times briefly over a 1.5hr phone call). Our system uses VoIP only inside our local network, we have an MTS PRI for outbound calls.
Anyone have any ideas or pointers?
Thanks;
Mark
