asterisk users - Jun 2004 - Codecs and pauses

Hi all

My * implementation is working brilliantly with only one small fault left to
kill.
I'm using IAXTalk from Telappliant for my incoming/outgoing calls to the
pstn network; if I set my codec to GSM everything works great - no pauses
but quality is a bit poor.  If it set the codec to alaw (I think I'm using
the correct one - I'm in the UK) I get intermittent pauses on the call.

Initially I thought it was just a connectivity thing but I get a latency of
less than 10ms to iax.voiptalk.org and I'm using a 2mb leased line.  To
further ensure it wasn't something on the line I've disconnected
everything
except the * box, a 7960 phone.

My phones are all 7960's using SIP.  There is a X100P card in the server moh
timing etc but it isn't connected to the pstn. 

The * box itself is a PIII 833 with 256MB.  Not at all stressed as this is
all it does.

Any hints or tips would be really useful as I'm stumped now.

Thanks

Matt

Hi,

I've been having similar problems to you. I found after reading an
unrelated post, about the Jitterbuffer option in iax.conf, setting this to
yes has made things much better.

Now the problem I have is that telappliant have lost one of there external
routers so I can't connect at the moment :-)

What is it with networks breaking today, first Dilbert and now
Telappliant??? :-)
