Chapter 10 Migrating to an IP Telephony Network
Reference Models for Migration Configurations
Audio Messaging Interchange Specification Analog (AMIS-A) networking of
voice messaging systems is planned for a future release of Cisco uOne. When it
is available, if both Cisco uOne and the voice messaging system are configured
for networking, it will be possible to provide basic voice mail messaging
functionality across the systems (provided the voice messaging system supports
AMIS-A).
The following configuration steps are required for the type D system:
Step 1 Configure PRI link—same as for type A system.
Step 2 Migrate each user—same as for type A system.
Step 3 Migrate each user in voice mail.
a. Delete mailbox on voice messaging system.
b. Add users in Cisco uOne.
Step 4 Move PSTN trunks from PBX to IP network—same as for type A system.
The following list summarizes the cost of the type D system:
Hardware Software
• PRI gateway for IP network
• PRI card on PBX
• Nothing extra on
Cisco CallManager
• PRI software on PBX
