[Asterisk-Users] Migration to Asterisk - Running off of Merlin Legend system

[Wade Weppler]

If the voicemail interface really is analog, then the identification is done
through DTMF codes.  You'll just have to figure out the format of these
digits and let Asterisk deal with them as you want.

Most systems with analog voicemail ports work just like this.  We've
interfaced Asterisk with a Norstar system using Norstar's VMI interfaces.
The Norstar VMI sends a specific format of DTMF codes (programmable) that
indicate the called extension.  Fancier systems can indicate the reason for
the transfer (busy/unanswered), the caller's number (via CID) and the called
extension.
