3.3.7 Example 7: Practical Application of ISDN-NT

Based on Example 2 - Basic Configuration and Registration for ISDN, we will introduce
the practical application of ISDN-NT.
Generally, the practical application of ISDN-NT falls into the following two sections.
Connect the telephones (Please refer to VoIP Example 1). Two VoIP equipments call
with each other.
Connect PBX's Outside Lines. The usage is the same as that of ISDN line. Different
PBX has its own settings and required configuration by you. Below shows a scenario
architecture graph:
WAN IP
3300V+ 220.135.240.207 Port1(ISDN-NT)
2910V 61.31.167.135
Suppose there are two ISDN lines connected to PBX's Outside Lines. The third Outside Line
is connected to 3300V+'s ISDN-NT Port1. The Inside Line is connected to a telephone with
the extension 101. If the extension wants to dial VoIP using Line 3, you must firstly press 3,
and then dial the phone number.
