I think I have Isolated the problem to one site and not for sure how to fix it. This site has 10 phones with the AX controller 5 phones are 5330E and 5 are the 5224. I am sure the problems is with the networking, but their IT guys does not know how to help. They have Cisco SA 520 VPN router that per specs is not capable of options 128 or 129. they have a Cisco SF 300-24P switch and our Mitel. DHCP is only working on the Mitel but all the phones and pc's running through the phones had to be manually set.
I think somehow in the networking at this site; the phones and network traffic is getting confussed on the route paths causing the audio loss.
Any Ideas all the phones are setup with the same subnet?
