Introduction
Bizphone Gateway feature helps customers to integrate Bizphone with the existing PBX / VoiceGateway.
Example:
- User is currently using an analog phone system.
- User purchases additional Bizphone service.
- User wants these 2 systems to work smoothly together.
- In this article:
- Legacy extensions are extensions from the old PBX system and range from 100 to 399.
- Bizphone extensions are extensions purely set up in Bizphone subscription and range from 400 to 499.
Configure and Use Gateway
There are 2 approaches:
- Do not deprecate the old system but using 2 systems simultaneously.
- Purchase new Bizphone extensions.
Reason to choose:
- Cost-saving
- Remain in the current PBX SIP and extension configuration.
- Bizphone Gateway reduces operating costs by connecting a legacy business phone system with dynamic SIP trunking services.
- The existing system is too bulky to migrate.
Configuration:
- Purchase SIP subscription(s).
- One analog gateway is equivalent to one SIP account.
- Toggle on Bizphone Gateway mode for the SIP account(s).
(Go to SIP app > Account info > Advanced configuration > Choose mode: Bizphone Gateway > Update)
- Map manually the legacy extensions (100-399) to the newly purchased SIP account.
Make calls with SIP Gateway:
- Outgoing call:
- Call flow: Phone > Analog gateway > Bizphone extension
- Add the SIP account to the SIP list at Settings > Outbound Rule so that it can make calls using the Rule.
- Otherwise, the calls are not considered Bizphone outgoing but SIP outgoing; their logs are located at the SIP app.
- Incoming call:
- Incoming call -> Bizphone extension –> SIP gateway account (for analog gateway) –> Analog gateway -> Phone
- Calls to the gateway extension (100-399) will be forwarded to the assigned SIP account
- Calls to Bizphone extensions (400-499) are received at the Bizphone extensions themselves.
- Internal call:
- From legacy extensions to new extensions: press the extension number
- From new extensions to legacy extensions: configure the Dial plan as the example below:
- Explanation:
- If the number starts with 1 and has a length of 3 (i.e. 100-199), forward to SIP gateway sip1020987.
- Result:
- Press extension key #123, the call will reach extension 123 in the legacy system.
=> In our example, the legacy extensions range from 100 to 399 and are mapped to 3 SIP accounts. The final dial plan will be:
Reasons to choose:
- Maintain the current Analog PBX system and utilize full Bizphone functionality (DNC, call recording, etc.).
- To fully sync with Bizphone and other Cloud solutions.
=> It is easier to Call Internally when you follow this approach.
Configuration:
- Purchase the SIP subscription(s).
- One analog gateway is equivalent to one SIP account.
- Toggle on Bizphone Gateway mode for the SIP account(s).
(Go to SIP app > Account info > Advanced configuration > choose mode: Bizphone Gateway > Update)
- Purchase Bizphone extension, 500 extensions in total (400 extensions to map with legacy extensions and 100 new extensions)
- Configure SIP account on customer’s analog PBX.
- Map the SIP account to Bizphone extension:
- Go to Bizphone app > Settings > Bizphone gateway > Choose the extension(s) > Map it with a SIP account > Apply.
- Can choose more than one extension at the same time. Extensions that are already mapped are not listed to choose from.
- One extension can be mapped to ONLY one sip account.
- One sip account can be mapped to MORE than one extension.
-
5. Do not need to register 400 extensions (100-399) to devices. Instead, make sure the incoming call device is Ring SIP.
- Use Caller-ID for DNIS: Technically, our system will use Ext Key (e.g, 101) to push calls to your PBX system by default. If you prefer us to use Ext’s Assigned Number (e.g, +656517xxxx, please tick Use Caller-ID for DNIS.

Make calls with SIP Gateway
- Outgoing call:
- Call flow: Phone -> Analog gateway -> Bizphone extension
- Add the sip account to the SIP list at Settings > Outbound Rule so that it can make calls using the rule. Otherwise, the calls are not considered Bizphone outgoing but SIP outgoing; their logs are located at the SIP app.
- Incoming Call:
- Incoming call -> Bizphone extension –> SIP gateway account (for analog gateway) –> Analog gateway -> phone
- Calls to the gateway extension (100-399) will be forwarded to the assigned SIP account
- Calls to Bizphone extensions (400-499) are received at the Bizphone extensions themselves.
- Internal Call:
- Press the extension key to call from extension to extension
