I'd like to have the SIP domain that jigasi calls out to hardcoded, so that
in jitmeet one needs to only input the userid part of the SIP callee.
Where can I change this in the code? To better illustrate with an example,
I'd like to restrict calling out to my.domain.com and have jitmeet users
only enter the user/extension. So to call firstname.lastname@example.org, a jitmeet
user would only need to input 2000 in the telephone menu.
Is this possible?
