Suppose I have a static address or dyndns set up.
I would like to be able to receive a SIP call to SIP:ShaleTest@11.22.33.44:4444 that would still work if the connection to a SIP provider were somehow lost. Could I, and if so how would I, set that up to my OBi202, preferably in OBiTalk?
Presume 11.22.33.44 is my IP number I have opened port 4444 to the OBi202. I understand I would still want to prevent SIP scanners. But since SIP scanners can make it in, I was thinking this may be possible.
