DECT C4010 Hang up problem

[tbzropi1]

Need Help
I have a client who has a big trouble, when he become a call on his DECT C4010 and when the conversation are finished they hang up pressing the line botton, one of they take one more time the line, and it still hold the line always giving a busy tone.
There isn't any timeout to set, clearing the line.
The release of the PBX is 25.15 and is a DMC8 system with 47000203 Firmware.
Bye

C4010/C4020 is one of the worst experiences I ever had.
But things to check is:
DMC8 software should be 47000206.
Dect servicepack 7 is as far as I know solving almost all of our known dect problems.

What software do you have in the C4010:s?
Check by pressing "menu 9 8 9 7" on the handset.
It should be 51G.

The handsets themselfs are major parts of the problem.
We have changed all of them on some sites and all problems are gone!

Other dect dmc8 issues to check:
DMC8 cards rls 1 has been causing to put basestations to "sleep mode".
Only 5 basestations on each DMC8/8E card should be powered from the card itself. If you want more basesstations, install local powering.
(Dont forget to change to local on OTM)
