Mitel NuPoint Messenger Technical Documentation - Release 7.0
 
Successful pages are retried a specified number of minutes apart (the pager interval), for a 
maximum number of times (the pager frequency). Paging is discontinued when any of the 
following occurs: 
• 
The frequency number is reached 
• 
The user listens to all unplayed messages in the mailbox and logs out 
• 
The user disables paging 
Unsuccessful Outdialing 
If the server encounters a Busy or Reorder tone, or a Ring No Answer condition after outdialing, 
the call is considered unsuccessful. Other examples of unsuccessful calls are if no dial tone is 
detected, or no tone or voice “greets” the server after the page is made. The server retries the 
page according to the busy frequency and busy interval. 
When the server detects that an “illegal” dial string (that is, a string that does not conform to 
configuration rules) has been outdialed, it considers the page successful. This prevents the 
server from continually retrying the page. However, if a dial string is configured incorrectly (that is, 
it cannot activate the pager), but conforms to pager configuration rules, the server continually 
retries the page. This is why it is critical to test every pager immediately after configuring is 
completed. 
Note:  If you are using answer supervision (the L code) in any of your outdial strings, your outdial is 
considered a failure unless the server detects a ringing on the line. 
Billing Considerations 
The billing function is capable of billing both paging and message delivery on a per-call basis. 
Remember, however, that the server site is the calling party and thereby responsible for any 
charges that accrue when paging or message delivery calls are made to the outside telephone 
network. As stated earlier, pager calls are usually of very short duration, but message delivery 
calls can be quite long. Since the cost of each call depends on the time of day that it is made, the 
duration of the call, the distance between the server and the user, and the rates of the local 
telephone company, the server makes no provisions for this aspect of the billing. 
Outdial Billing 
Outdials such as paging calls can, however, be billed back to a mailbox owner’s account. This 
form of outdial billing can be implemented through individual mailboxes’ configuration and is 
explained more fully in the Mailboxes chapter. 
Here is an example: 
Henry Huggins has a pager and has his pager calls billed to his calling card number. To perform 
this manually, you lift the telephone receiver; wait for a dial tone; dial 9 to get an outside line; 
listen for a dial tone; dial 0-612-555-4534 (0 indicates you will charge the call); wait for a 
computer tone; dial the calling card number; wait for another tone; dial his mailbox number, 6446; 
then dial # to tell the pager that all the display data has been entered. (This activates the pager). 
The dial string for these actions is: 
Caller Action 
Dial String 
Wait for dial tone. 
Dial 9 to get outside access. 
Wait for second dial tone.
