Outgoing Calls - PRI
When placing a call using a PRI facility, you may want to append a # to the dialed number. This signals the facility that the number is complete and causes the call to be placed immediately.
The outgoing telephone number that matches the digit pattern in the Network Selection Table is deleted automatically. This is not programmable. The common carrier ID is sent to the foreign exchange.
In systems that are programmed using a non-uniform extension dialing plan, one base number may not be able to represent all telephones.
To specify that no telephone number is sent to the network, choose the Do Not Copy Telephone Number programming option and use the Telephone Number to Send procedure to ensure that telephone numbers are not assigned to each channel in the B-channel group. A network option to block presentation of CPN is also available.
If ARS identifies a call as applying to a call-by-call B-channel group but the Call-by-Call Services Table does not show a matching digit pattern and bearer capability, the call is rejected.
Outgoing calls using call-by-call service selection can be made by pressing a line button, pressing a Pool button, dialing a pool number, or using ARS.
The Call-by-Call Services Table must be programmed for the Call-by-Call Service Selection feature to take effect. If a service is not specified in the table, the entry is ignored.
An SMDR record is not recorded for any call on a PRI facility that is shorter than the programmed SMDR Call Length. Usually, the SMDR Call Length is programmed to compensate for connection and ringing time of calls on non-PRI facilities before they are answered. For systems where most lines are PRI lines, the call length should be programmed for one (1) second.
