One way audio will usually be due to NAT problems. Eg the IP in the SDP is an internal IP so it can send audio but the remote end doesn't know where to send audio to in the other direction. Echo on a VoIP call would be due to one of the endpoints. Sent from my iPad On 6 Nov 2012, at 16:41, "Sean Devoy" <sdevoy@bizfocused.com> wrote:
Hi, I have a client who has been working fine for months, but as of late they are reporting connections where the audio only works in one direction or neither and “terrible echo”.
I know they had some issues with their local Cable Connection, but they are supposedly resolved. Results from “ping –n 50 –l 256 ” and “tracert” are virtually identical to mine from here and I have no issues. Are there some diagnostics I could run to try and pin this down. The phones are all cisco 504Gs, the server is a VPS from synapseglobal.
Thanks for any ideas you may have. Sean _________________________________________________________________________ Professional FreeSWITCH Consulting Services: consulting@freeswitch.org http://www.freeswitchsolutions.com
