Distribute Calls To Multiple Carriers¶

This technique is based on the last number of the telephone being dialed.

1. Setup your carriers and enable them all.
2. Create your dial plan entry like the examples below:

Carrier 1 dial plan
exten => _81NXXNXXXXX[0-3],1,AGI
exten => _81NXXNXXXXX[0-3],2,Dial(SIP/${EXTEN:1}@Telco1,,tTor)
exten => _81NXXNXXXXX[0-3],3,Hangup

Carrier 2 dial plan
exten => _81NXXNXXXXX[4-6],1,AGI
exten => _81NXXNXXXXX[4-6],2,Dial(SIP/${EXTEN:1}@Telco2,,tTor)
exten => _81NXXNXXXXX[4-6],3,Hangup

Carrier 3 dial plan
exten => _81NXXNXXXXX[7-9],1,AGI
exten => _81NXXNXXXXX[7-9],2,Dial(SIP/${EXTEN:1}@Telco3,,tTor)
exten => _81NXXNXXXXX[7-9],3,Hangup

Carrier 1 will be used if the telephone's last number falls between 0-3; Carrier 2 for 4-6; and Carrier 3 for the remaining numbers
