Make use of the VOIP technique, one of the biggest advantages is that changed the physics distance to voice communication, having no concept of long distance, and it is also easy for deployment. In some enterprises, there are a lot of branch organizations, having a lot of employeeses working outside. In this kind of case, deploy the SHANG332 will solve the enterprise internal communication, save the cost of long distance call very much. Use the telephone from outside like they are in the local office. In contactl center, this form can forward the agents to any place if there are any internet connections.
Remote telephone extension
Before reform, each branch organization contact by llong-distance telephone call. After the reformation, they can talk through the IP network. It is free and easy. They call to Other’s extensions by directly input the extension number. This kind of application is particularly useful in the long distance call center.
Transform method
Increase two customer lines under the PBX of the headquarters, number are 803 and 804, directly connect to a FXO gateway; place another equipments in the branch organization, install the number to 803; if the scale is bigger, you could consider to use the softswitch or IPPBX.
There are a few keys:
ü What to use is the FXO gateway in the PBX side, it need to transparent deliver the signal and voice. After get the call sign from the distant VOIP equipments, it can automatically build up with the PBX connection. After it receives the PBX call sign, it can automatically call the VOIP equipments of the distant place.
ü This FXO gateway must set to the right signal with PBX. Especially for the busy tone detection. It is useful for not hanged up on phone lines.
Let’s take SHANG332 as an example, explaining to set the device:
1、 the PBX side FXO gateway setup.
a) The equipments’ IP address and SIP information
In the “quick setup” page, fill the network parameter and VOIP parameter. Suppose we use the method of Peer to Peer. Notice the Enable Registration and the Enable Proxy constitution items are to No.
b) Configure for accept the distant VOIP call
In the page of “port configuration”, set the FXO gateway’s 1st and 2th port phone number of voip to 9803 and 9804, this 2 ports will link the PBX line number 803 and 804.
c) Call to distant voip gateway setting
In the “FXO Advanced Configuration” page set working mode to “auto mode”. When gateway is in auto mode, call from PBX to FXO gateway, this fxo gateway will call the FWD number automatically, so that it will connect the distant voip device.
Click the Display Auto FWD NBR button to set FWD Number.
Set 1st and 2th port FXO number is 803 and 804. It is correspond to PBX extension 803and804.
In the “Route direction table”, set all number that start with 8 forward to voip.
Set Peer to Peer Calling Route Table, set all number that start with 8 forward to 192.168.1.21.
2、 Remote FXS gateway setting
The equipments’ IP address and SIP information
Set phone number
At the Advance=> SPS set each ports’ hotline number.
This hotline number is the correspond FXO Gateway port’s voip number. When distant caller pick up the phone, the distant FXS Gateway will connect to FXO Gateway automatically.
It is need point 9xxx number to voip too.
After the reform project complete, when call from pbx to remote extension, calls reach PBX’ 803, FXO gateway would start call to 803(the FWD number) numbers; at the branch organization, when caller pick up the handset, (hotline number is 9803, 803 is the extensionses of headquarters), the distant voip gateway will directly connect 803 FXO gateway in the headquarters. after hearring the dial tone, then dial the destination number as you at local extension.
