Static problems with Asterisk + Polycom phones
...is significant static when making SIP ->
PSTN calls. SIP -> SIP and SIP -> VM calls are totally clear and fine.
Here's the setup:
Polycom 601,501, and ten 301s.
Digum 2400 TDM card w/echo cancelling, 12 FXO ports.
The TDM card is on IRQ 5 with nothing else on it.
Server Specs:
Asus P4P800E Deluxe
P4 3.0 Ghz
1 GB Ram
80 GB SATA HD
- There is no static when using a normal phone direct to the 66 block.
- The sound is also a bit low, and bumping the volume on the Polycom
phones makes the static alot worse (obviously)
