Asterisk API - call forward, speed dial, etc

Hi ambiorixg12,

Thanks for the reply.

We are not looking for any channel related function… I have found those details.

We are looking to get/set an user/extension call forward details.
We are looking to get/set an user/extension speed dial details.
We are looking to get/set an user/extension voicemail password.
etc…

Basically all user/extension based functions.
