I've been trying to attach a Pantel VoIP door phone to an existing SPA9000. That was not a trivial task as configuring the Pantel VoIP to register with the SPA9000 as an extension results with any other extension being able to call the Pantel VoIP while the Pantel VoIP not being able to initiate a call to any of the other extensions (6 rapid busy tones). Now this is a big bummer as the whole purpose of a door phone is its ability to call in and not the ability of internal extensions to call the door phone....
After many hours, I did manage to find a solution:
The idea is to use one of the SPA9K Lines as an interface for the Pantel VoIP. In order to do that, you'll need to choose a line (I'm using Line2 as Line 1 is attached to a SPA3102 PSTN GW).
SPA9K configuration:
Goto Admin->Advanced->Voice->Line2.
Line Enable: YES
UserID: 2000
Use Auth ID: No
Contact List : Hunt group or internal extensions you want to ring when pressing the CALL button on the Pantel VoIP.
Use outbound Proxy: No
Use ob proxy in dialog: No
Register: no
Make call without reg: YES
Ans Call without REG: Yes
Submit All Changes.
Pantel Configuration:
System Page
Username: Set the extension number for the Pantel.
Password: Leave empty
User domain: SPA9K IP
Proxy IP Address: SPA9K IP
Proxy Port: 5061 (For line 2... 5060 for Line 1, 5062 for line 3, etc.)
Auto registration: Disable
Code Type: U-Law
SUBMIT
VoIP Page
DTMF SIP Presentation Mode: Transparent (If you want the ability to press a button on the extension in order to open the door)
Call button dialing - day mode destination: 2000 (Note that it has to be the same as the UserID of the Line interface you have configured on the SPA9K
SUMBIT, then REBOOT
That's it. That should get you a Pantel / Pancode VoIP calling into the SPA9K with the ability to talk to the person at the door and open the door by pressing a key. Note that I'm still working on the abiltiy to try and initate a call from an extension to the Pantel VoIP although it is not a functionality I really need.
