Router VoIP Magic – SIP and ALG settings

Lately I have been using more than one viewer for activity in the virtual world of Second Life and encountering problems with connecting to the Voip services. Vivox is the voice communication software used in most Second Life viewers.

This is all in the realm of magic to my mind though I know that it is just arcane, not unknowable. But I got a clue one day when the viewer software reported a problem from the server trying to give me access to voice. This alert message appeared and provided me with some clues for research:

I then found this forum discussion where a fellow was asking about ports, but the repair was to disable SIP ALG.:

Since changing that setting I have been using all my Second Life browsers without any problems connecting in voice.
