How do I set gigaset s150 to increase the number of rings.

I don't think u can, after 25 rings it usually goes to answer phone automatically, if its going to answer phone b4 that then turn answer phone off the automatic setting.

Change the ringing tone...

maybe your number is listen

I need the manual to set it up

hello,all you need to do is just to go to your phone settings,go to the ringer settings and increase it to your desired step.
yo can as well follow these shortcut,
when you dial a number on your phone,you then press the upper key down you will see the ringer bar showing on your screen,you can then increase it to your desired volume.

wish you success,

take care.

Hello,

I have the same phone system, and *think* you may be able to fix the problem by adjusting the amount of rings before answer on each unit. This assumes there is an auto answer system engaged. Hope that helps some.

Press
function
64
set

look at the printout
look for number of rings

to set the parameter
press
function 74
set

the default setting is 5 rings. if you need to change that:
set the ring to answer to higher number, however, that will put the machine in manual answering of fax.
the better setting is to rest the phone or the answer machine to a lower number of rings.

From the main menu select the Voice Mail option in Voice mail select Ring Delay in Ring Delay you can choose the delay time before Answering Machine pick up the phone from 0 to 30 secend.Reza from Iran

press *94, then press the number of rings you want 1-9. The tone will change and thats it.
