I have a Asterisk box and as Consultant I am often at other offices.
I would like to get my phone calls there on my VoIP phone, but only if I am there.
Is there a way that I dial a number (“I am here now”) and all calls would be forwarded to this (remote) number.
Since I would use that phone also for making phone calls, I would like to open it for other calls with the same procedure.
When I am done working there, I would need to dial a number and cancel this settings, means the phone can only call my office (no PSTN calls) and no calls from my office would be forwarded.
How can I do that?
