That would be a little more ideal but the way in which the faxes pass though
the system the both the port/channel and the destination are dynamic. There
are some special situations that I have some modems that are dialed enough
that they are specified. These specific destinations go to another context
or rather Special case Macro for their dialing. That special case Macro
does not initiate a monitor on the channel. By the way, There are separate
contexts for outbound and inbound calls. As a matter of fact there are
separate contexts per LEC also so I can load balance traffic.
All Extensions in and out are over PRI channels. PRI Spans are front ending
switches until development of all applications to Asterisk is complete. It
may always have to do this in some situations. Since this is true there is
now way to tell what the actual devices are that are dialing behind the
first switch. I would normally do this by looking at the CLID or something
set by the first switch only it does not allow me to do it on a per port
basis.
I know that I will probably have to add some FXS ports or ATA's to Asterisk
and move all the fax/modem devices over to there but that will take a while.
So back to the drawing board. Maybe this will just have to be added to
Monitor having it exit it hears fax or modem tones. Still can not think of
why it would interfere at all though.

Subject: Re: [Asterisk-Users] Small problem with FAX and Modem.
What if you separate the fax machine channels to diffrent contexts that
don't call application Monitor ? It's for outgoing calls and for incoming
calls if you have certain extensions for faxes you can call StopMonitor
application.

is
causes some funky transmission errors with the modems and sometimes
Faxes to
the point where about 50% of the time the devices just give up.
What I would like to do is if the systems detects a modem or a fax jump
to
another point in the sequence that disables the monitoring. On inbound
calls this is more obvious but on outbound calls I am not sure of how to
accomplish it.
Sort of an aside to this is that after I started recording all the calls
I
have also seemed to introduce some echo somewhere. The echo was not
present
before monitoring but not sure why it would introduce it either.
Any help appreciated.
