Symmetric NAT handling issues

[jdstroy]

Hi all,

AOL's AIM Phoneline stopped working as of this year, so it looks like I'm back to using Voxalot again, since Voxalot is one of the few providers with Symmetric NAT handling / RTP relays.

Only... I can't get Voxalot's RTP relay to work reliably.

I've followed the guides posted, and my settings are configured to use Symmetric NAT handling.

Can anyone help me out here? I can provide diagnostic logs, traces, and everything else as needed. I have used Xlite, SJPhone, Phoner, PhonerLite, and probably a dozen other VoIP softphones, and all of them experience the same issue.

I also have a secondary location that is behind a "Full Cone" NAT. This location does not require the RTP relay, and all SIP clients work properly with and without the relay there. I've considered running my own relay from there; however, the machines at this location are shared-use, and they cannot run background processes for extended durations.

Thanks in advance!
