Hi Patrick,
There are 2 main issues we need resolved when using the SPA525 with Asterisk 1.6.2.5. The 2 issues are parking and Intercom.
Parking.
Typically what we've been doing in the past for parking with other phones is a feature which will allow the user to press a 'park' button. This will essentially transfer the call to a parking lot (ie 700). The system will then play out which parking space it's in (audio) before the use hangs up.
The solution provided in the past
--
- Define PSK1 as : fnc=sd;ext=700@$PROXY;vid=1;nme=Park
- confLx|1;flash|1;xferLx|2;conf|1;xfer|2;toggle|4;redial|5;dir|6;bxfer|4;park|8;phold;psk1|3

was not successful, because what happens is that the phone sends the call to parking lot but hangs up in doing so. Thus you never hear which parking lot number. This function needs to be more like an *attended transfer* rather than a *speeddial* which just hangs up.
ICOM, (Intercom)
We need a way to use a directed Intercom. A user presses an 'ICOM' button (can be a prefix), and then waits for the user to enter the recipients extension. The recipients phone needs to automatically pickup speaker. We are doing this server side. What the PBX is expecting to see is a *xxx (where xxx is the extension). The PBX will then send the appropriate 'ALERT' to the recipients phone to auto answer call.

exten => *201,1,SIPAddHeader(Call-Info:\;answer-after=0)
same => n,Page(${PageDevice},i)--
was not successful, because the string provided by O'Reilly must not be right because the phone never auto answers. We tried multiple variations of syntax, which none were successful. We need you to tell me *exactly* what the phone wants to see!
thanks,
ci
