My friend’s AVAYA IP Office PBX systems has feature called “Mobile Twinning”, this feature allows an external phone to be twinned with internal extension. the twinned device can be any external phone such as mobile or home phone.
so when caller rings the extension, both extension and the twinned device will ring. if the call is not answered from either device then the call will follow the rules set up for the extension. (such as being redirected to voicemail)…
I am running Asterisk 1.8.4
is it possible to have such feature?
I need advise
Thanks & Regards
