Hi,
I've been playing
round with Asterisk on Redhat 9 (2.4 Kernel) and was experiencing bad echo
problems using Budgetone 100's when calling analogue lines in uk (Isdn4Linux /
Digi Datafire). Calls to other ISDN and mobile network seemed ok although not
much testing done.
I've tried
installing Asterisk on a faster processor (P4 3.0 GHZ) with a 2.6.8-24 kernel to
see if that helps. Using the latest version of Asterisk from CVS all seemed to
compile ok but I'm getting weird errors.
When I place/receive a call between SIP/SIP SIP/ISDN etc all seems to work ok until either end picks up the phone. The following error occurs:
Jan 13 18:32:51 NOTICE[23016]: Unable to find a
path from g723 to slin
Jan 13 18:32:51 NOTICE[23016]: Unable to find a path from ulaw to g723

Jan 13 18:32:51 WARNING[23016]: Bridge failed on channels SIP/Phone4-cfa4 and Modem[i4l]/ttyI1
And the call is dropped........
I'm using the
identical config files from the Redhat installation that worked fine
(notwithstanding echo!).
Anyone else seen
this or have any suggestions what the problem might be?
Cheers,
Andy
