I agree that they should provide SIP. And indeed releasing
sccp only while stating you are switching to SIP sounds
conflicting.

Agreed.

Yeah, but still I can live with that because all the other
things make up for that.
The only annoying thing I have is the GroupPickup not
working. Besides that they do all the SIP version does, and
more.

If you loose the PBX there are more problems.
I don't know how the SIP image handles this, but I do know
the SCCP image can be configured to failover to a second
PBX. That way we can continue everything we do when 1 of our
PBX boxes decides to die.

As you can see, it all comes down to a matter of personal
taste. That's why they should release SIP, just to give you
the ability to choose.

Coming back to the OP question, the SCCP image gives you a
lot more control over the buttons. It involves some altering
in a .c file, but there you can specify your layout as you
want it.
