IP Phone 7821 call functions

[PhillipeAxtelecom0062]

Hello. 

It's my first time using a Cisco product and I'm trying to validate the IP Phones CP-7821 with our production PBX Asterisk.

I'm not sure the Purchasing dept bought the correct model for this implementation.

The telephone upgraded to 12-7-1 FW and loaded the SEPMAC.xml file successfully using my TFTP Server.

The account registered in Asterisk and I'm able to dial and receive internal and external calls, but some functions didn't work. Transfer and conference buttons worked only using "Recents" hotkey like I'm not able to enter a phone/extension number manually.

The DND function isn't available, and I can't add manually a number in the phonebook (Message "Contacts not available" appears when I hit the button).

I can't change any config by the web page of IP Phone.

Asterisk: v1.8.32.3

IP Phone: CP-7821-K9= v08

Enterprise FW: sip 78xx.12-7-1

Can I use these functions using Enterprise FW or I need to change to the 1MPP FW?

Using a device with enterprise phone FW (intended to be used with a Cisco call control) you really don't have any guarantee of what features will work, aside from making and receiving calls. Pretty much as using a 3rd party device with CUCM.

Enterprise FW doesn't provide a config GUI, just a view only GUI.

If you need to fine tune the messages that are sent when you press any of the softkeys or hardkeys on your device to match what your PBX needs to make them work, or want a config GUI, you need the 3PCC/MPP firmware.

Either ask the seller to swap the device, or you can use the procedure at upgrade.cisco.com to migrate to MPP FW (fees may apply)
