Separate Phone lines for Internal and External

[Visad]

In a new condo there are two phone lines coming out of the wall.

One is for internal calls and one is for external calls.

Is there anyway to combine them into one phone that can then make and receive both internal and external calls?

Thanks.

Well that is strange, I have two phone lines in my condo but one was for 3bb and one was for TOT..... I use both for 3bb (2 ADSL lines - 0 TOT Telephone).

Yes, with a mini PBX.

This is one of many: http://www.aliexpress.com/store/product/mini-PBX-Telephone-Switch-System-SV308-3Phone-Lines-x-8-Extensions-PABX-for-small-office-use/803866_537932324.html

Just connect it to your two lines and plug your existing phone into it.

You can also find new phones with a built-in two-line mini PBX for an all-in-one-box solution.

How about a simple 2 line phone?

Wasn't aware of two line phones. Will have a look for one, how does it know which line you want to dial on?

Those PBX looks a bit expensive.

Thanks.
