Commonly, because of firewalling and/or NAT. Given that your client 10.35.229.11/24 and the server 10.35.229.5/24 are both on the same subnet, it's not going to be a NAT problem, so I would look at the firewall rules, both on your machine and the one you are connecting to. (Please do tell us if the client and server are not connected directly through a switch as I have assumed here, and there's possibly something more complicated going on.) You want to look for firewall rules which will allow UDP in both directions on ports 10000 - 30000 (typically, may vary a bit, but something like that), or alternatively, look for any rules which would block this, and remove them. If that doesn't appear to be the problem, do a packet capture of your SIP traffic and look for the Invite and the reply, each with the SDP payloads, to find out what IP addresses and port numbers the client and server are advertising to each other. The only other thing I can think of right now is codec compatibility. Antony. -- I know I always wanted to be somebody, but I guess I should have been more specific.
