>
> Today I had a strange behaviour:
> I am routing calls to an Asterisk PBX. It has a very sophisticated
> dynamic least cost router built in - so I use it to terminate mobile
and
> international calls.
>
> For a first test I created a dialplan which checks for ^231$ in the
> dialled number and then routes the call to $1/asterisk.pbx.
> It didn't work. Grepping the SIP traffic I could see that Freeswitch
> makes an invite $1@asterisk.pbx. Yes it's $1 in the SIP message.
>
> Second I checked for the mobile number using ^(01[6-7]\d{4,13})$ in
the
> dialled number and then route the call to $1/asterisk.pbx.
> This works.
>
> I am confused as in the second case $1 is translated to the dialled
> number and in the frist case not.
>
> Anybody has a clue?
