Why use an SCR over an MCR?

I keep running into this and I'm wondering if there's a reason behind
it I'm missing:

On new installs, many installers opt to make the second line on a phone
in another range (e.g. 2215 and 3215) using SCR keys instead of two
lines with the same number using MCR keys (e.g. 2215 and 2215).

I love MCR keys because it doesn't confuse the users wondering what
this other extension is. I have consistantly re-programmed phones to
have multiple MCR keys.

Is there any reason NOT to do what I'm doing? It seems to make sense,
but on almost every install I have encountered, 2 differently numbered
lines are what have been programmed. Why do that as a default?

Any thoughts?


Re: Why use an SCR over an MCR?
There can be different reasons after the idea, ask the one who created it
that way.

for example.
Key 0 scr in a NON-DID reange for internal calls and outgoing external
Key 1 scr in a DID reange for incoming external calls.
If one of these lines is busy, you can give a Hunt treatment for that line.

With key 0 en 1 MCR with the same DN, you are not busy when you already have
a call on 1 key.
You can only give Hunt treatment when the DN is busy,  in this case both
keys are busy.

Ofcourse MCRkeys  can have his advantages but also SCRkey can.
It depends on what the customber wants and what is the best solution for
this customber.

Every advantage has his disadvantage and every disadvantage has his

Re: Why use an SCR over an MCR?
With the SCR and hunt format you can put the two scr lines on
different phones and be able to pick them up at different locations if
they are put on hold.  This works when the secretary is supposed to
answer the boss's line when he is not in his office if he asks her to.
Otherwise she would let the call should go to the boss's voice mail.
IF only one phone is involved the MCR format would work great.  I have
not thought of it as such but this will solve some of my Caller ID
problems.  Thanks

Hi Alex,

I agree with you, I've converted our call center to 2 MCR with the same
number instead of the SCR method, done that 5 years ago haven't looked back!

I'm curious also on why they still do this?
