VoIP Trunking Application 3
– Regular Phone to VoIP Phone Call
How to Make Phone Call from Regular Phone to VoIP Phone?
1.
Dial the PSTN number of the ZyXEL Trunking Gateway (A).
2.
The ZyXEL Trunking Gateway (A) picks up and waits for caller to enter a phone number when it
receives the call. If the caller does not enter another number, the ZyXEL Trunking Device (A)
connects the call to Phone 2.
3.
Enter the destination SIP number of the ZyXEL device B.
If the
Auto Attendant Authentication
on the ZyXEL Trunking Gateway (A) is not enabled, it
directly forwards your call to the ZyXEL Trunking Gateway (B) and rings Phone 3.
If it has
Auto Attendant Authentication
enabled, the IVR in Trunking Gateway will prompt you
to enter the password. If your password matches then it forward your calls to the SIP number of
the ZyXEL Trunking Gateway (B) and rings phone 3.
