I'm looking for some info from anyone who has experience (hopefully successful) running Cisco 7925g IP phones on Aerohive. We have been struggling for some time with various issues and are trying to work all possible paths to resolve them. Many of our problems are likely due to design issues (less than optimal placment of APs, etc.) which we are in the process of correcting with help from an outside partner.
Naturally we also need to determine if we have configured the Aerohive infrastructure optimally to support voice. Unfortunately Aerohive support has not been able to provide us with much specific information for our Cisco phones as far as configuration for the best interoperability. I've read through every post on this forum that I can find related to voice and have used much of the information I've found. One thing I'm hoping someone might be able to shed some light on for me is regarding call admission control on Aerohive specifcally. When I read the Aerohive documentation about enabling call admission control it only mentions SIP and Vocera voice traffic but our Cisco 7925g phones run Cisco's SCCP. Will enabling CAC have any effect in this case?
Also, in 6.1x versions there are several new features related to "Voice Enterprise". These relate to various 802.11 standards that our 7925g phones do support. One of these items I'm not so clear on is the WMM Admission Control. What is the difference between the WMM Admission Control (located in the Advanced settings for the SSID) and Call Admission Control (located under Advanced Configuration > Management Services > Management Options)?
Does anyone have any other advice specifically related to the Cisco 7925g on Aerohive? Aerohive does not have an interop guide for this handset so I've been working from Cisco's 7925g Deployment Guide. Cisco's guide is written for Cisco wireless, but much of the information is applicable to any system.
Any info would be appreciated as I'm trying not to leave any stone unturned.
