[Asterisk-Users] No ringing tone with IAXY (and other bits and bobs)

[Chris Orme]

Hi!

I'm really hope you can help me solve a little mystery, the mystery is
probably just my misunderstanding ! sorry...

I've got an iaxy talking to my * box which connects to two providers.
I'm running the stable release of the pbx.

The only thing is that when dialling from the iaxy the ringing tone isn't
heard while calling someone - you just hear silence then, they either
answer or they don't on the remote end.

>From my extensions.conf is the following - I tried putting the ,r in and
it doesn't help.  Is there some other option I could try here ?

Also I'm getting quite a bit of echo noticed at the remote end as well as
the iaxy end.  All lines are digital, I guess only the jitter buffer is
there to be tweaked to try and help ?

There is also this echo problem with the sipura, but not with an ATA186 or
snom.  The lack of a ringing tone is only with the iaxy.

The Answer,Hangup lines were to solve 'busy' situations with SIP phones,
without this or even with 'Congestion' they just rang forever if a number
was busy.  They seem to need the 'Answer' line.

If you know a nicer or more correct way for me to do this please let me
know as most times the SIP phone user will hear half a ring and then the
hangup noise generated by the SIP device when a number they call is busy.

Many thanks!!

PS please Cc: me a copy as well as to the list in case I miss it -
Thanks.

Is the definitive order these should be in listed anywhere as I know it
really seems critical and lines can be ignored if they're not in spot on
the right order?
