This is still an ongoing problem, and it appears another one of our customers is having the same problem. I have an 871W router doing PPPOE over wireless Internet, with an EZVPN tunnel back to our servers and gateways. Call quality is good, never have any packet loss, and jitter is low. It's just the signalling to the phone. Sometimes when I place a call I get a slight delay. Occasionally when I answer a call, it will not pick up, the phone bleeps, and rings again, then I can pick up the call, and it answers immediately. Other times it picks up, and the softkeys remain unchanged, the phone number of the caller remains above the softkeys, I can hear the caller, but they cant hear me, then the number changes to connected, the softkeys change to the connected call setup (hold, transfer, etc.) and everything is fine. Other users who are over EZVPN on the same ASA do not have this problem. I also have a 7921 wireless phone that experiences a delay, far less frequently than the 7970 does. I had the problem with a 7960 before that, and swapped out the phones. The phone is SCCP if that helps any. My router does not have any firewalling applied to it, no inspects, no ACL's, just NAT for Internet, the voice is clear over VPN.
