We've got PBX to configure. It's based on Elastix 2.4.0, freePBX 2.8.1 and Asterisk 1.8.20.0.
Currently we have a setup for inbound calls like that:
Inbound call > Announcement (30 sec) > IVR (no sound, for extension dial only, 5 sec) > Queue (for timeout on IVR, aka Callcenter)
Boss wants me to do some tuning: disallow external caller to dial certain extensions directly (like 141, 142, etc.) so the only way they (callers) could get to these numbers if someone (like 140) will patch them through first.
Could you suggest me what needs to be done? I've been configuring through Elastix until now, so if it should be done other way, extensive directions would help me a lot.
