Carl Johnson Posted August 25, 2008 Report Share Posted August 25, 2008 We all know about NAT and its unfreindly nature concerning VOIP .. that said I am having a bit of an odd issue that just does not make sense as the SBC should resolve this, I think? Polycom (not the greatest for external applications) .. will establish the SIP session and register as well as initiate a call but the audio (RTP) coming back from the PBX is always addressed to the wrong IP? Any thoughts on this does not seem to be an issue with a softphone and other hardphones in the same external network .. just the Polycom?
