MultiVOIP FXS Quick Start Guide Phonebook Tips

3.Knowing When to Drop Digits.

When calling area codes and access codes are used in combination, a leading “1” or “0” must sometimes be dropped.

Phonebook Entry

Example

Area code for Inner London is listed as “0207.” However, in international calls the leading “0” is dropped.

4.Using a Comma.

Commas are used in telephone dialing strings to indicate a pause to allow a dial tone to appear (common on PBX and key systems). Commas may be used only in the “Add Prefix” field of the Inbound Phonebook.

5.Ease of Use. The phonebook setup determines how easy the voip system is to use. Generally, you’ll want to make it so dialing a voip call is very similar to dialing any other number (on the PSTN or through the PBX).

6.Avoid Unintentional Calls to Official/Emergency Numbers. Dialing a voip call will typically be somewhat different than ordinary dialing. Because of this, it’s possible to set up situations, quite unwittingly, where phone users may be predisposed to call official numbers without intending to do so. Conversely, a voip/PBX system might also make it difficult to place an official/emergency call when one intends to do so. Study your phonebook setup and do some test-dialing on the system to avoid these pitfalls.

7.Inbound/Outbound Pattern Matching. In general, the Inbound Phonebook entries of the local voip unit will match the Outbound Phonebook entries of the remote voip unit. Similarly, the Outbound Phonebook entries of the local voip unit will match the Inbound Phonebook entries of the remote voip unit. There will often be non-matching entries, but it’s nonetheless useful to notice the matching between the phonebooks.

8.Simulating Network in-lab/on-benchtop. One common method of configuring a voip network is to set up a local IP network in a lab, connect voip units to it, and perhaps have phones connected on channel banks to make test calls.
