ThomasAJ Posted March 22, 2008 Share Posted March 22, 2008 I have set up ET on 4 PCs. 3 work fine but the 4th. has no audio inbound. During the setup the ET Wizard said that a Firewall was blocking UDP port 5060,5070, 8000 etc. I have no firewall on that PC and ALL PCs access the Internet thru the same router.

pythonpoole Posted March 22, 2008 Share Posted March 22, 2008 The router has a built-in firewall that will control access to each PC individually. Even if you forward port 5060 for one PC, on another PC it will still be blocked. Also, you should make sure that the RTP port setting (under Options -> Network tab) should be a high value, for example 8000 - 16000. The low port numbers are more often than not blocked by the router's firewall and this can cause problems receiving/delivering audio. Also try this, put the call on hold for a few seconds and then take it off hold. Is the audio problem corrected? Also make sure your stun servers are active, or if you prefer you can manually enter the IP address, SIP and RTP port details. Link to comment Share on other sites More sharing options...
