auto-attendant, voice conferencing, and PSTN access, digital and IP-based communications.
Based on state-of-the-art embedded technology, the IPX-1900 provides a solid, uniform platform for
voice communications as well as data network communications. The IPX-1900 offers a seamlessly
integrated solution for the up-to-date telecommunication needs. The future IP PBX telephony system
offers all of the essential features of telephony which is required by small business/enterprise users for
their telecommunication/data needs.
Being more flexible, the IPX-1900 integrates up to 4 calls via the IPX-19FO (2*FXO) / IPX-19FS (2*FXS)
/ IPX-19SL (1FXO+1FXS) module to become a feature-rich PBX system that supports seamless
communications between existing PSTN calls, analog, IP phones and SIP-based endpoints.
The IP PBX is the feature-rich SIP based IP PBX telephony system that integrates NAT functions to
make it perfect for small business usage. The IP PBX integrates traditional PBX system functions and
provides many advanced functions including voice mail to email, web management etc.
Designed to run on a variety of VoIP applications, the IP PBX provide IP-based communications, voice
conferencing, and call detailed record (CDR), centralized Auto-Attendant (AA), and Interactive Voice
Responses (IVR). The IP PBX utilizes standard PSTN/GSM lines via the interfaces of FXO/GSM
gateway to become a feature-rich IP PBX telephony system that supports seamless communications
among existing local calls, SIP-based endpoints including low cost of long distance service, telephone
number portability and one network for both voice and data.
With the IP PBX, standard SIP phones can be easily integrated in your office. Users may integrate
PLANET IP Phone VIP-254T series, VIP-255PT/ 350PT/ 351PT, the ATA-150 / VIP-156/ 157/ 158/
161W of ATA (analog telephone adapter) series, the VIP-191/ 192 of Wi-Fi Phone, and Gateway series
VIP-281/ 281GS/ 480 to build up the VoIP network deployment in minutes. Allowing distributed IP
technology to meet traditional voice services with proactive managed interface, the IP PBX for
enterprises in the daily business processes can make people more productive, more intelligent tasks
and more customer satisfaction.

SIP Basic Setting

SIP (Session Initiation Protocol) is a request-response protocol, dealing with requests from clients and
responses from servers. Participants are identified by SIP URLs. Requests can be sent through any
transport protocol. SIP determines the end system to be used for the session, the communication
media and media parameters, and the called party's desire to engage in the communication. Once
these are assured, SIP establishes call parameters at either end of the communication, and handles
call transfer and termination.

¾ Scenario Sample
IP PBX has created two different SIP trunks and one Gateway trunk for outgoing trunks.
Figure 3-21. Trunk Group sample setting
One-Stage Call:
1. If user dials 81123456, this call will hunt SIP_Trunk_1 and send 123456 to call out.
2. If user dials 82234567, this call will hunt SIP_Trunk_2 and send 234567 to call out.
3. If user dials 0345678, this call will hunt FXO_Gateway and send 345678 to call out.
Two-Stage Call:
1. If user dials 81 and hear the dial tone, then dial 123456. This call will hunt SIP_Trunk_1 and
send 123456 to call out.
2. If user dials 82 and hear the dial tone, then dial 234567. This call will hunt SIP_Trunk_2 and
send 234567 to call out.
3. If user dials 0 and hear the dial tone, then dial 345678. This call will hunt FXO_Gateway and
send 345678 to call out.

Dialing Rules

When want to make VoIP calls through the above FXO, SIP or Gateway Trunk, the user can use the
