Patchy sound has absolutely nothing to do with the 7960 software. All
versions from 2.1 through 6.0 have been solid as a rock from a usability
standpoint. If you have patchy sound, look towards improper configuration
of the phone vs asterisk definitions.

In my (somewhat biased) opinion, the 7960 is "the" top of the line
once
you understand sip/rtp basics and provide the network infrastructure
to support the basics. (It's also the most expensive even for refurb
7960's. Your milage may vary.)

I avoided the Cisco v5 code for some time due to the back-level warnings
published by Cisco. However, I upgraded to v6.0 code and would recommend
it at a heart beat. It's been absolutely solid, stable, and they finally
added some rather useful "user" features.
