[Asterisk-Users] Supplementing Current phone system

[Ben Turner]

Has anyone used * in conjunction with an existing phone system to add
certain features or to expand a department?  Currently we have an existing
nortel phone system.  We would like to have the * server stand behind it and
just handle VoIP services for our remote sales and technical people.  We
would like them to act as normal extensions (being able to dial them by
extension from the existing phone system and have them dial extensions on
the existing phone sytem).
