Bridging
What is Bridging?
Bridging is the ability to conference two difference interfaces into one call.
Why do you need Bridging?
Bridging provides you the freedom to conduct a conference call with participants that are communicating using different interfaces. It allows one participant to be on a VoIP platform and another to be on a telephony platform while all parties can talk to and hear each other.
How does Bridging work?
Any Phoenix Audio device with more than one interface has the ability to bridge calls. All you have to do is connect the device to two different interfaces and then just initiate or receive a call with each interface. The device will automatically connect the bridge and you will have the ability to control the outbound and inbound audio levels for each interface.
Example:
When using a PSTN Spider (MT502), connect the device to a landline via a phone outlet. Then, connect to a computer via a USB cable. Now, you can dial someone with an analog phone line using the keypad while initiating a Skype call with someone else on your computer. Both parties will be able to speak to you as well as to each other without any need for additional hardware or software. The table below displays the bridging capabilities of each device:
