I was wondering if there is any recent bug free software pack and ios version that has been released after the 12.4(22) YB4 which i can use for a new install.
Also which was the last most stable version of ios and software pack that i can use for a brand new install?
UC520 or UC540?
Both are here:
UC540 comes with the latest from the factory.
Scroll down for UC520 7.1.3 EA pack, which will be a default factory release in a matter of weeks (the TME can comment further on that)
I have actually installed the 7.1.3 release in a recent deployment. This customer was using Cisco 7960G phones. I had discovered problems calling out when I first installed the UC520, but that problem was fixed by disabling the g729br8 codec, but leaving the g729r8 codec enabled.
Will CUE 7.1 get included in non-Early Adopter UC520 and UC540 software packs?
I am aware of one problem in the IOS version included in the 7.1.1 software pack. This problem appears to not occur with the IOS image included in the 7.1.3 early adopter release, even though I am really unsure if the problem has really disappeared in the 7.1.3 early adopter release. As far as I know, this problem does not occur in the IOS images included in the 7.0.2, 7.0.3, and 4.2.x releases.
Here is the description of the problem with IOS 12.4(22)YB1, the IOS image included in the 7.1.1 software pack:
The problem described above is known to occur in IOS 12.4(22)YB1 with Cisco 7931G phones. As far as I know, this problem does not occur with the 12.4(22)YB4 release in the 7.1.3 release, or the 12.4(20)T2 release included in the 7.0.2 and 7.0.3 releases.
Here is a similar call setup, with an outbound call made on a 7960 phone connected to a UC520 unit running IOS 12.4(22)YB4 (which is included in the 7.1.3 software pack):
The above test scenario was from a 7960 phone to a fax number. I was doing this to be sure that re-INVITEs were being handled correctly. I want to be sure that the call was still connected and that G.711 mu-law audio was being sent after the re-INVITE had been acknowledged, even though the fax machine might disconnect the call or we might hang up after the re-INVITE is acknowleged.
