How to Dial to Originate a Call from Within the Dialplan?

Question

Salvete! How can I dial a number and have Asterisk originate a call from extension sipX to sipY?

Both sipX and sipY appear in extensions.conf of my dialplan.

The trick is that I want to dial 337 on my phone, and then my phone goes out of the picture, then sipX calls sipY.

Say I want to be able to push 337 on the phone, and have a sound played over the speakerphone of another phone, say, as an alarm.

---

Another way to consider it is, how can I do this:

1. Push 337 on my phone
2. complete my call, that is, hang up the original caller
3. run a macro even though there is no call in queue
4. call sipY
5. play a sound on sipY

When running the #2 action (completing the caller's session) and letting the rest of the process complete afterward, can we use something like the pre-dial handlers in Asterisk 11?

Answer 1

Here is the answer. You place Answer as the first part, and end with 'hangup'. That takes care of the "busy signal".

No AGI. This works.
