directDID-Callback

We have a Callback module running on a live Asterisk server, would like to build a module “directDID-Callback” to extending the features . The operation should like that : 1. User registered the phone (Mobile or landline) number in member area to use these “directDID-Callback” features 2. Users use the registered phone (mobile or landline) to call a close-set local PSTN number which we provide (this PSTN redirect to VOIP number) 3. After connected, user dial 2nd group digits for the global destination number (terminate with # key) & hang-up 4. Callback activates and dials to registered phone, than destination number We provide test-server enjoinment for developing need. After all tests are passed on test-server, service provider should support the buyer to complete and success implements the modules onto the live server with details instructions.
