Hello everyone,<div><br></div><div><br></div><div>I'm having an issue with a VoIP provider where the gateway will respond to any random port instead of 5080. I sent the corresponding trace to the provider and they told me to "disable rport and nat". I removed the auto-nat parameters in the corresponding sip profile, but I keep having the same issue (I don't think it has anything to do with nat anyway).</div>
<div><br></div><div>On the trace I noticed that INVITEs sent by FS have an empty rport parameter on the Via header, but according to what I've read, this is standard and it indicates that the response should be sent to the originating port (5080), which is not being done by the gateway ("Avaya SIP Enablement Services"). How may I go about solving this? should I set the rport parameter to something specific (eg. 5080)? or remove it altogether?</div>
<div><div><br></div><div><br></div><div>Thanks,</div></div><div><br></div><div><br></div><div><br></div><div>Nico</div>
