> wrong handset rings and can't take inbound calls. Welcome to SIP Natpocolypse.
This - specifically the wrong handset ringing - is caused because the router you are using is forgetting which phone is mapped to which port. The super simple easy way to fix this is to give every phone a unique SIP port - for example, if you have extensions 300, 301 and 302, go into the phone configuration interface and set their LOCAL SIP PORT to be '5300' or 5301, or 5302, etc. That is normally enough to make your router NOT fiddle with SIP traffic and try to remap it.
