recall 600-900 ms MX-One

[Patolin]

Hi.
I need to make recall of 600 or 900 ms in MX-One, and I have some panasonic phones. Modify the ASPAC
Aspace: parnum = 252, parval = 160;

Aspace: parnum = 253, parval = 122;

and restart the unit ELP6 and nothing happened.

Is good or to do something else?

Panasonic telephone sets have hookflash timing from 90ms to 600ms. It is easy to change the hookflash timing of panasonic phones, in normal case it will be mentioned in the booklet which will be there in the panasonic phone box pack.
