Feature Name : Trunk Reversal

User Code : Outgoing call from a reversal enabled trunk.

Programming Code : 

Command details to Enable / Disable Reversal on trunk:

260

Trunk line

Reversal on/off

Call Maturity on/off

260

01~16

1 / 0

1 / 0

 

Default Value : No reversal  on trunk detected. Only call maturity timer works


Feature Type - Programming 

Description of the Feature : This command is used to detect the trunk reversal and calculate precise call duration in outgoing calls.

How to Use : Enable Reversal on a trunk using 260 command, and it will be sensed for each outgoing call from that trunk.

Example:-

To program trunk reversal on trunk lines 01 and 03, and store outgoing calls as per reversal and call maturity both on trunk 01 and only reversal on trunk 03.

  • To program all trunks simultaneously, use the ‘#’ key in place of trunk line
  • Check the outgoing call details on the reversal programmed trunks to confirm the call stored is as per reversal / maturity delay (R / D).
  • Default setting: All trunk lines are reversal disabled, and their calls are stored as per maturity delay timer (91023 programming – default = 30 sec)

Restrictions : The trunk provider must provide reversal on trunk. Some GSM providers may generate reversal by default, and some of the GSM FCT's detect the reversal.

Modifications / Suggestions : 

This feature is best applicable to hotels, where there is a need for calculating the exact call durations.
