Hi, I am trying to get a prototype working based on Asterisk and Quicknet cards. I currently have to systems set up each with a LineJack card. I have the systems working, but can't get the voicemail demo to work properly. Messages to the user telephone set from the voicemail system are clear, but recordings left through the phone are distorted. Sounds like the audio has lots of echo and sampling error type distortion. I know this must be covered in the archives, but I can't find a reference. I am using the Asterisk demo configurations. configuration is as follows: ; ; Linux Telephony Interface ; ; Configuration file ; [interfaces] ;mode=immediate ;mode=fxo mode=dialtone ;format=g723.1 ;format=slinear format=ulaw silencesupression=no ; ; List all devices we can use. Contexts may also be specified ; context=local context=default ; txgain=100% rxgain=100% device => /dev/phone0

In reading the comment that slinear would sometimes cause crashes, I changed to use the gsm codec. When I tried to use the system, I would always get a error on playing back messages because a recording in that format was not found. Changing it back to slinear made it work great. BTW, if you can get the LineJack to dial outbound on the PSTN, let me know. Haven't managed to get that to work just yet.
Hi, I am going to try this question once again. Does the lack of response imply that everyone has abandoned LineJack cards for use with Asterisk?
