AGI - Dialing Special Extension

Hi there!

I’ve written an AGI script that does some processing of info on our server.

I now want to have the script dial a special extension to complete a directed pickup but I can’t work our the AGI command to send through!

I’ve tried:
EXEC DIAL SIP/*881234
EXEC SendDTMF *881234

Neither of these work.

Anyone able to help?

Thanks in advance.
