I'm wondering if this is possible (in general, with voip) or specifically with voip.ms.
If I have a static IP (internet or WAN IP that is, static because I pay extra for it) and if I configure a non-standard SIP port in my router to forward from WAN to my ATA, can I set (somewhere in my VSP's account portal) my IP and port? So no more polling or nat-keep-alive every 3/5 minutes (etc) is needed to be done by the ATA?
