[*] Garbled Outbound Audio

[Chris Friesen]

What card and server are you using to run Trixbox?  

 

We had a similar issue using Switchvox on an HP DL360 and a Digium PCIe
card. We were able to match the random static with error messages in the
/var/log, it turned out. What we were able to determine is that there was an
issue with the digium driver and asterisk regarding timing that was causing
this. We changed cards (which changed drivers) and the random static
stopped.

Subject: [*] 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
