Sounds like no comfort noise.....do you see this as well on VOIP trunks? sign up for goiax or something like that to test....I tend to think it is between asterisk and the polycoms. You could also test with a Sipura SP3000 as a replacement to see if you have the same issue, or if you have an extra FXS card, cross connect one of the FXS to the FXO channels. My FXO's in the adit 600 are fantastic. -D

CallerID, disconnect supervision work perfect, however the users complain that they have some sound quality issues, after testing it I realized that whenever one is in a phone call they get like silence between the sounds coming from the other party, almost like a cell phone, in other words if there is no sound coming from the other party it sounds like they have hung up, which is very annoying. The usres all use Polycom IP 501s connected to Asterisk which is running a a TE110, here is the configs from the Adit: ------------------------------------------------------------- -Adit 600 configuration file -Created on 01/04/2002 at 14:26:40 for root -This file is valid for the following configuration only: - - CardType - -------- -SLOT A T1x2 SW Version: 9.0.0 -SLOT 1 FXOx8 -SLOT 2 FXOx8 -SLOT 3 FXSx8 -SLOT 4 FXSx8 -SLOT 5 FXSx8 -SLOT 6 RTRx1 -NOTES: -1.
