could someone comment on the use of 7931 as a non-extensible combination of 7960 and 7914 for a CCME environment. I have an installation that only requires 16 buttons on the "attendant console" and I was wondering if I could use 7931 for this. I am aware of the restriction to single line ephone-dns only, but can the other buttons be programmed as speed dial buttons with DSS (single button transfer) and BLF functionality? Obviously, for transfers, one would need two ephone-dns as explained in the CCME 4.0(3) features manual.
Not sure what limitation you are referring to. We use the 7931 with dual-line DNs and everything works fine including transfer and BLF/DSS.
Overall I like it better than a 7961 + sidecar, because the backlighted display that makes it easier to read.
If you feel adventurous, look at linksys 962 + 932 extension. I cannot guarantee that all the button features would work immediately as it is a SIP phone and not SCCP, but now, that is a really nice phone. Hopefully cisco will borrow this design soon.
Hope this helps, please rate post if it does!
