asterisk users - Oct 2003 - ChanIsAvail app setting ${AVAILCHAN} to an unusable value.

I sent this earlier under "Editting variable contents" but no-one
has responded.  So, the subject is now more to the problem, instead of
the solution I was trying to implement.

ChanIsAvail returns the channel ID plus "-<session>".

How can I edit ${AVAILCHAN} to remove this session ID, so I can use its
contents in a subsequent Dial statement?

Dialing on Zap just gives a warning about unknown option "-", but
dialing a SIP channel completely errors out.

Oh, it's quite simple.  You just write your own application to remove
the suffix.  Or you wait for someone else to write it.

Untested code.  UAYOR.
