Follwing the information from the wiki
(http://www.voip-info.org/wiki-Asterisk+phone+snom) and the mailing list, I
have been able to get my Snom 190 to monitor extension states accurately.
I have noticed a couple oddities, however, that I am hoping I can get
explanation on so that I can know more about * and SIP:
- It appears that I cannot use variables in the "hint" priority exten
lines.
So "exten => 22,hint,Zap/2" will work fine, but (assuming Ext22 =
Zap/2)
"exten => 22,hint,${Ext${EXTEN}}" will not. Why is that?
- It appears that the extension used with the "hint" must be the same
as the
extension used to dial that channel. So if extension 22 will ring Zap/2,
then "exten => 22,hint,Zap/2" will work, but "exten =>
222,hint,Zap/2" will
not. Why is that?
- If I am correct in the above, then there is no way for me to monitor a
channel that is not an extension. As an example, I have a TDM400 with 3 FXS
(Zap/1-3 on extensions 21-23) and 1 FXO (Zap/4) as well as a VoIP channel
for dialing out. I can monitor the states of the extensions with extension
entries like "exten => 21,hint,Zap/1" but I cannot monitor the
state of the
FXO with "exten => 0,hint,Zap/4" because 0 is not the extension
of Zap/4.
Indeed, Zap/4 has no extension. Is it not possible to monitor that line,
then?
Thank you very much!

There are 10 kinds of people in this world:

The hint feature is not a well developed general status monitor, it's just a *static* method to define the state of an extension as the state of a device for those channel drivers that support the extension state "API". It can't be dynamically changed (it's not an executable dialplan element, like an application), and by implementation it is an extension state, not more.

Why is that?The extension is how asterisk maps SIP URLs to chunks of your dialplan -- if you program a button on a snom to "dest <sip:12345@your-asterisk-box>", the phone will use that same URL for both dialing and subscribing to extension state. Unless you have a phone that lets you specify different URLs for dialing and subscribing to state, they have to match in asterisk.> - If I am correct in the above, then there is no way for me to monitor > a > channel that is not an extension.
