It's often difficult for people to wrap their head around it at first when they aren't completely familiar with VoIP but after a VoIP call is established the phones (hard/soft, doesn't matter) talk directly to each other with a switch or PBX no longer involved in the network conversation at all once the call is established. The lack of audio is simply a routing problem. If this is any clearer than mud, does anyone have any ideas? My research so far has turned up lots of leads, but none which actually lead anywhere.Įasy VPN is mean to be easy and it is when you have only two sites it pretty much can be but add a third site and it isn't going to work so well. Even hard-coding the IP address of the phone wouldn't let it contact the IP Office. I compared the two ASA configs and did not see a difference that should affect this. Related to this last bit is that I cannot get an IP Phone to talk to the IP Office in Location A from Location C, though this did work from Location B. The call is placed through the IP Office appliance in Location A. As I understand it, point-to-point traffic is necessary for the audio on VOIP to work, at least for Avaya. Calls from Location A and another location (different kind of VPN back to the ASA in Location A) work fine. This came to light when I received a call at Location C from Location B and got the ring but no audio.

I tried various ACLs, but only succeeded in making more problems, not resolving any. I can't reach anything at Location B, however. From Location C, I can touch devices in Location A with no problem. Location B is the old remote site, and Location C is the one I am trying to set up. Getting EasyVPN up and running, with access to the central servers has been no problem.

I am definitely learning this as I go along and am a bit stumped about a couple of things so I wanted to call on the expertise of this community. I am trying to set up another office, also on a 5505. We have a multi-site network, with ASA 5505s at two locations configured for EasyVPN.
