[ 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.

The same escaping should apply there for extensions.conf as it's a config
file thing, I don't use AEL and don't know anything in that regard. It
may work the same way there.

How very odd.  It is working now.  I am sure I did nothing different
than the first time.
