AMIS Delivery |
| Check this check box to designate the port for making outbound AMIS calls to deliver voice | |
(available with the AMIS | messages from Cisco Unity subscribers to users on another voice messaging system. | ||
Cisco Unity supports the Audio Messaging Interchange Specification (AMIS) protocol, | |||
licensed feature only) | |||
which provides an analog mechanism for transferring voice messages between different | |||
|
| ||
|
| voice messaging systems. | |
|
| This setting affects outbound AMIS calls only. All ports are used for incoming AMIS calls. | |
|
| Because the transmission of outgoing AMIS messages may tie up voice ports for long | |
|
| periods of time, you may want to adjust the schedule on the Network > AMIS > Schedule | |
|
| page so that outgoing AMIS calls are placed during closed hours or at times when | |
|
| Cisco Unity is not processing many calls. | |
|
| ||
TRAP Connection | Check this check box so that subscribers can use the phone as a recording and playback | ||
|
| device in Cisco Unity web applications and | |
|
| least busy ports. | |

The Number of Voice Messaging Ports to Install
The number of voice messaging ports to install depends on numerous factors, including:
•The number of calls Cisco Unity will answer when call traffic is at its peak.
•The expected length of each message that callers will record and that subscribers will listen to.
•The number of subscribers.
•The number of ports that will be set to dial out only.
•The number of calls made for message notification.
•The number of MWIs that will be activated when call traffic is at its peak.
•The number of AMIS delivery calls.
•The number of TRAP connections needed when call traffic is at its peak. (TRAP connections are used by Cisco Unity web applications and
•The number of calls that will use the automated attendant and call handlers when call traffic is at its peak.
It is best to install only the number of voice messaging ports that are needed so that system resources are not allocated to unused ports.
The Number of Voice Messaging Ports That Will Answer Calls
The calls that the voice messaging ports answer can be incoming calls from unidentified callers or from subscribers. Typically, the voice messaging ports that answer calls are the busiest.
You can set voice messaging ports to both answer calls and to dial out (for example, to send message notifications). However, when the voice messaging ports perform more than one function and are very active (for example, answering many calls), the other functions may be delayed until the voice messaging port is free (for example, message notifications cannot be sent until there are fewer calls to
