Hrm.  This is probably going to be pretty basic, but some googling
didn't seem to come up with anything.  How do you do this when you are
assigning to a variable in extensions.conf such as:

FRED=PJSIP/outgoing/sip:fred at sip.example.com;transport=tcp

The ; is taken as a comment starting character, isn't it?

Even in AEL:

FRED="PJSIP/outgoing/sip:fred at sip.example.com;transport=tcp";

The ;transport=tcp doesn't seem to survive.

I can add it onto the end of the variable in the Dial() command:

Dial(${FRED};transport=tcp,${timeout},TtWw);

and it has the desired effect, but of course specifying at the point
where the Dial command is sets the transport policy much too broadly.

Cheers,
b.

You escape the ; character by placing \ in front of it. IE:

DIal(${FRIED}\;transport=tcp,${timeout},TtWw);

[ the part you trimmed ]:

and it has the desired effect, but of course specifying at the point
where the Dial command is sets the transport policy much too broadly.

So per the above ("has the desired effect") one doesn't even have
to
escape the ; in the Dial() command.

But I don't want the ";transport=tcp" hard-coded into the Dial()
command argument where the Dial() command is executed.  That is making
a transport policy (i.e. not every destination that gets to that Dial()
command should use tcp) decision for far too many destinations.

The ";transport=tcp" needs to be added where the destination is
defined
into a variable:

FRED=PJSIP/outgoing/sip:fred at sip.example.com;transport=tcp

in extensions.conf or:

FRED="PJSIP/outgoing/sip:fred at sip.example.com;transport=tcp";

in extensions.ael.

Cheers,
b.
