Re: [asterisk-users] Re: Inbound Voice Quality - Speed Change
13/15 is good, and Im not saying this is definately the issue, but it's just a thought I had. Download pingplotter (pingplotter.com) and run it to the teliax server for about 30 minutes, or so. Set your test interval to 1second.See if it makes a nice steady line, or if it looks like a city scape (bad). Especially take notice what it looks like during calls in which the audio is screwed up.

It doesn't always happen, and seem unpredictable. This sounds like a timing issue. Do you have zaptel cards installed or ztdummy? If zaptel cards, are you getting your timing from the telco or providing your own? I shut off the line that was providing timing from the telco on another system (not asterisk) and all heck broke loose. I had called to cancel the line a few days earlier and it took a couple days for them to cancel it, so basically had forgotten about it. Took me awhile to figure that one out. ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

[asterisk-users] Re: Inbound Voice Quality - Speed Change
Lacy, I'm using asterisk 1.4.2 and zaptel 1.4.1. I read the READMEs again. I believe I need to change my kernel RTC to 1000HZ. Also, I didn't have enhanced_real_time clock enabled, as such, ztdummy wasn't loading properly. I have rebuilt and started testing again. Thanks for the replies!!

Lacy, How I have this: ztdummy 4424 0 rtc11156 1 ztdummy zaptel178084 1 ztdummy crc_ccitt 2016 1 zaptel ztdummy is loaded, and * is running, however, I would have expected ztdummy to be used by at least something.
