Asterisk ARI create outbound call

Question

I'm trying to initiate calls using the ARI API, the process I followed was

1. POST /ari/channels to create channel 1 to the local extension
2. POST /ari/bridges to create a bridge
3. POST /ari/bridges/{bridge-id}/addChannel with channel 1
4. POST /ari/channels to create channel 2
5. POST /ari/bridges/{bridge-id}/addChannel with channel 2

I have a websocket connection waiting for the correct events (like channel status up) before calling the POSTs.

The problem I'm having is this works using internal extension numbers for channel 1 and channel 2, but when using an external number for channel 2 I get the error - "Allocation failed".

Any ideas where I'm going wrong...

Answer 1

Im creating my calls via ARI like this:

http://{ARIUser}:{ARIPass}@localhost:8088/ari/channels?endpoint=SIP/{exten to call from}&extension={number/exten to call}&context=from-internal&priority=1&callerId={callerID}

When you create channel with ARI to address "/ari/channels" you MUST define "extension" or "application" parameters (read more https://wiki.asterisk.org/wiki/display/AST/Asterisk+12+Channels+REST+API#Asterisk12ChannelsRESTAPI-originate).

Digitum make very unusable Python ari module and you may play with my module (now not implemented events) on https://github.com/vit1251/ari2.
