Why do you have two sets of double quotes in your destination number expression? That could be causing your error. Your guess is correct; you should be able to match your expected string with something like the following: <condition field="destination_number" expression="^(\+C\d+)$"> You need to escape the "+", match "C", and match any number of digits. Note the one set of double quotes surrounding the expression. On Mon, Jan 19, 2015 at 3:17 PM, Magnus Kelly <magnus.kelly@gmail.com> wrote:

It's well within standard and actually required for many platforms.

What does your bridge string look like?

Hello Guys,

Is it possible to use FS with alphanumeric characters in the SIP invite?

As in I would like to send an invite addressed to +C27344xxxxxxxxxx as one of our upstream platforms uses a C prefix.

What I observe with default is " [ERR] mod_sofia.c:4431 Invalid URL "

If possible to support what would need to be changed? I am assuming that this is outside the SIP standards, but confirmation would equally be useful.

Thanks Magnus

Hello Kristian,

I also re-read bit further and figured out it was a silly question as how else would names be used, however I am using a simple dial plan - as in the below -

<extension name="test"> <condition field="destination_number" expression=""^(\d+)$""> <action application="export" data="dialed_extension=$1"/> <action application="set" data="call_timeout=30"/> <action application="set" data="hangup_after_bridge=true"/> <action application="set" data="continue_on_fail=true"/> <action application=³bridge² data="sofia/$1@10.x.x.x"/> <action application="answer"/> <action application="sleep" data="1000"/> </condition> </extension>

And when the incoming invite that¹s destined to dial out on other leg comes as ³ +C27344xxxxxxxxxx " I get the error as in ³ [ERR] mod_sofia.c:4431 Invalid URL ³

I will continue to review but thoughts welcome. my guess is need to study perl expressions. Thanks Magnus
