Hi Guys,
I have a client with ctx 670 and two line group.
both line group ring phdn 1000 right now and about 40 phones have phdn 1000.
and it works fine until now.
the problem is
when we have incomming calls by line group one
it rings Phdn 1000, one station(ext500) is speaker phone on after two rings, and then transfer to one station(ext369).
only line group one is doing this things.

I think ext 500 enables some kind of call forwarding.
how do I get rid of this problem?

I did ext button plus #6051, #6053, #6052 all kind of canceling call forwarding from user manual.
but it didn't work...

Please help me out...
I know some other system(like vertical and nec) has line group call forwarding...

Thanks.
