[Asterisk-Users] Hint with snom 220 - call pick up

[Alexis FECOURT]

Hi,

I am trying to use the support for monitoring extension states of a snom 
220.

In the extensions.conf file I added:
exten => 770,hint,SIP/770
It means that when the snom phone boots, it will register it-self to 
asterisk as a monitoring phone for 770: Asterisk knows that the SIP/770 
is monitored.

I am using the 3.56q-beta firmware.

It is in the DESTINATION option as it said on the tiki of snom in 
voip-info.org and not in the LINE option as it is said in the snom220 
manual that I put the SIP URL of the monitored phones.

I can see the used lines. But call pick up is not working: The snom 
can't pick up a call which has no answer.

Did I made something wrong ? Must I do something more ?
Please help me.

Alexis.
