Just want to verify one theory with you guys .
Centralized call processing, 7 digits for IP phone extension because of overlapped DID in different sites. Also for tollbypass automatically fallback to PSTN purpose we have to dial 8 as the prefix plus the 7 digits extension to reach remote offices phone.
For example, Phone A in site A has extension 2003333,3333 is DID. Phone B in site B has extension 2013333,also3333 is DID. Phone A dials 82013333 to reach Phone B.
Unity server is on site B. Unity pilot number is 2013000.My question is how the message button will work in site A. My theory is to create a new pilot number with prefix 8, say8201000 and assign this into a new voice mail profile, then assign this profile to all the phones in site A.
Will this work?
