Hi, I have home ezvpn clients (851s) terminated on a headquarter ASA5520, those home workers may call each other at home with Cisco VoIP phone behind 851s, call managers are in HQ, those VoIP phones have corp extensions. Often times users complain voice is one way and sometimes they don't hear audio at all,although call signaling seem to be perfectly fine.
I did ping test between hosts behind 851s, it is strange that sometimes the ping works but some times it does not, ping to HQ always succeeds. I could not think anything wrong with my configuration because in that case ping between spoke-spoke won't work at all. Do you guys have any idea what area I may need to look at? Thanks a lot,
