What's the version of Asterisk or whatever peer you're using on the remote IAX end?

By: Matthew Simpson (matthewsimpson) 2005-07-18 00:26:16

remote end is CVS HEAD 06-11-05

By: Matthew Simpson (matthewsimpson) 2005-07-18 00:48:04

seeing errors in remote CVS 06-11-05 log:
Jul 18 00:46:24 DEBUG[22040] chan_iax2.c: predicted timestamp skew (1127) > max (160), using real ts instead.

how is that an error?   Looks like a debug statement to me..

By: Matthew Simpson (matthewsimpson) 2005-07-18 01:03:03

semantics.

By: twisted (twisted) 2005-07-18 01:24:59

actually, it's not semantics.  you wouldn't even see those unless you had debug turned on.  I'm assuming there was some underlying problem though?  If so, what were the symptoms?

By: Matthew Simpson (matthewsimpson) 2005-07-18 01:50:11

the "underlying problem" was a 1GB debug file in a manner of hours.  there doesn't seem to be any kind of audio issues, but, as I mentioned in the bugnotes, i'm not using JB, trunk, or PLC.

By: Tilghman Lesher (tilghman) 2005-07-18 08:43:13

Please turn off debug in your log unless you are diagnosing a specific issue.  What it looks like is that you have a problem with a harmless message.

By: Tilghman Lesher (tilghman) 2005-07-18 09:20:00

Closing due to lack of specific issue
