CallManager 4.21 and 7921 Wireless IP Phone

[mwheinz]

Does anyone know if a Device Pack is required to use the 7921 with CCM ver. 4.21? I see where the phone is supported but need to know how to discover if a Device Pack is required. It's for an upcoming project and can't access the servers.

Thanks!

Here is the link to the compatibility matrix:

Scroll down to Table 51 for the 7921 compatibility.

Hope that helped.

No help, already saw that. Turns out you need 4.21 sr1b, install a Device Pack 4.21.06 and then install a firmware load.

Thanks! Oh, I work for ATT, too!
