If your subscription has more than 1 DID, click Customize it to forward incoming calls of each DID to a different number.
- DID number is your SIP subscription DID
- Backup number: external numbers that you want to receive incoming calls, e.g. your handphone DID. You need to add a back up number for each DID.
- Master Backup line number: an external phone number to receive calls when the SIP phone lines are down. Incoming calls to any SIP DID numbers that does not have a backup number will go to the Master Backup line.
