The Tech Connections Shared Line service enables you to have up to 6 devices or phones registered against a single Tech Connections number at the same time. When someone rings the Tech Connections number all phones/devices will ring at the same time. A great example of this is if you have Tech Connections App (Softphone) and a VoIP handset or dual mode cellphone.
Instead of having a Tech Connections number for your handset/cellphone and
another Tech Connections number for your softphone - simply use the same number
on both and no matter where you are people will be able to reach you. Tech
Connections Shared Line is also useful in a small office situation where you
have Shared Line and want it to ring all the office phones at once. Of course
if you're away from an area with internet access you can still use the
Simultaneous Ring service to have your cellphone or landline ring as well.

You should choose one device as your primary device. In the SIP settings for your primary device enter your Tech Connections number and password as usual. For each additional device you will need to add a suffix to your Tech Connections number/login. The suffix will need to take the format of a dash followed by the number 1-5. Each device will need a different number/suffix or else the service won't work. The password is the same for each device.
The maximum number of devices you can register against one Tech Connections
number is 6 including your primary device
