13.3 Call Rules

Call rules automate the forwarding of calls, first to a remote peer device and then to PSTN phones. This is used when you make frequent calls to several PSTN numbers in the same geographic area that start with the same numbers (for example an area code). If there is a remote peer device in that area, you can set up a VoIP link to it and have it forward the calls to PSTN phones. This works by configuring a pattern that the ZyXEL Device can recognize. A pattern is just the initial string of digits shared by the phone numbers. The following table shows the relationship between the phone numbers you want to call, the pattern you want to configure and the rule you want to set up.

13.4 VoIP Trunking Scenarios

There are several different VoIP trunking scenarios.

13.4.1 VoIP Phone To PSTN Phone

A VoIP phone A makes a call to the ZyXEL Device B via VoIP. B forwards the call to a PSTN phone C. A can be an analog phone connected to the ZyXEL Device or any other phone capable of making calls over the IP network.

13.4.2 PSTN Phone To VoIP Phone
