If the PSTN side is only complaining about conversations with a single phone on the SIP side, look at the SIP phone.
Check the settings for that SIP phone/PC (VAD disabled, NIC settings, runaway processes). Do PSTN callers here choppiness from the SIP phone caller? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Asterisk Sent: Monday, February 12, 2007 8:41 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [asterisk-users] Bad audio quality on SIP Hi guys, I have the following configuration: 10 SIP softphones <--> Asterisk <--> PSTN Audio is always good on SIP softphone side, but callers from PSTN side *sometimes* complain that the audio quality is bad (and volume low). The QoS is turned on on the computers where SIP softphone is installed, and the tos setting in sip.conf is set to 0x18. The interesting thing is that usually only one SIP softphone user (but each time someone else) would get complaints like that ... others seem to work okay. What could be wrong?
