Product overview

A 5m extension cable terminated with a UK telephone plug at one end & a twin BT socket at the other.

Can i use this cable to have parallel line from an same extension number. Ex two instruments connected to the same number.

Asked by: Lakmi
The cable would allow you to connect 2 telephony units to the same socket. Both units would share the line and number.

We are looking to buy an extra cordless phone system for our office as we need about 8/10 phones for our office. Currently we have 4 cordless phones running from one BT socket, would this enable us to buy a separate cordless system but use the same line?

Asked by: Lyn72
Yes, this would still only allow one active call at a time.
