[asterisk-users] Asterisk Usage Survey

[Matthew Fredrickson]

Hey All,

For those of you that do not know me, my name is Matthew Fredrickson
and I’m the project lead for the Asterisk project. First off, I wanted
to thank all of you that contribute in various ways to the project –
whether it be at a developmental level, answering questions on forums
and mailing lists, contributing documentation, or just generally
advocating for it within your sphere of influence. It takes so many
people’s efforts to make the project what it is and to sustain such a
large and vibrant user and developer community.

We created a general survey inquiring how people utilize Asterisk. It
should only take about 10-15 minutes, but would help us understand
better how our users are utilizing Asterisk and help us to understand
if there are important areas of Asterisk that we underemphasize from a
development perspective. If you don’t mind filling it out, it would be
greatly appreciated.

Thanks *so* much again for your time, and best wishes to each of you
in your efforts.

Since nobody offered up any BPs, I will provide the AEL macro that I
wrote to do this expansion:

macro expand_exten(ext) {
while ("${ext}" != "") {
Set(e=${SHIFT(ext,&)});
if ("${e:0:5}" = "PJSIP") {
Set(e=${PJSIP_DIAL_CONTACTS(${STRREPLACE(e,PJSIP/,)})});
} 
if ("${e}" != "") {
Set(newext=${newext}${e}&);
}
}
// blech!  global variables because there no way to make a
// function/gosub/etc that returns a value
Set(newext=${newext:0:-1});
Return(${newext});
return;
}

where the first argument passed in is an extention of the format:

PJSIP/

I'm pretty new to AEL, so any constructive criticism would be welcome.

Cheers,
b.
