Hi,

Has anybody been successful in running the 7914 expansion unit for the Cisco 7960G IP phone? For anybody unaware of what the expansion unit does, it provides 14 additional buttons, with an LCD display. The idea, is that with an expansion unit (a 7960 can take upto 2 of these units), a user can either assign more speed-dial's, or can monitor line status/account status. So, you can either register a speed-dial or register another account.

The problem I've found so far, is that speed-dials are not programmed on the phone, but are instead handled by the Call Manager software (not on a user basis, but on a phone, MAC address basis). Likewise, plugging the 7914 unit into the phone on an Asterisk PBX, just brings up 14 red lights (the buttons also light-up red, blue or green), which according to the hidden technical documentation, indicates that the Call Manager is not registering the unit. I can't work out if it's short of firmware embedded in the Call Manager, whether it's searching for a configuration file on the TFTP (Cisco phones need a TFTP to get their settings and SIP firmware), whether it's not happy with the phone being a SIP version, or whether I'm doing something wrong.

I've had to learn about the 7960's configuration the hard way, and despite their useless technical documents, have managed to configure most settings.

There's quite a bit of extra configuration for the 7960 I'd love to get to, and would like help or advice on. Things like directory services, screen logo, the 7914 and more!

If anybody is interested, I have resources and files to; convert from Cisco Skinny/MGCP to a SIP version, how to configure the VoiceMail indicator lamp, special key combinations to reset the unit (without pulling the plug out) and locking/unlocking the preferences, configuring the voicemail speed-dial

Any help or advice, please let me know!

Regards,
Ad.
