Using OpenSER


I intend to use openSER as a frontend and * for vm. I wanted to know from someone who is already running openSER, how you were able to register your phones on openSER prior to including the * vm part in the system? I have installed openSER and somewhat configured it with username/password/email information in the database but wanted to know if it normallly does not reigster phones that are behind nat’d firewalls.

Also, if so, is it also mandatory to install the mediaproxy server for nat’d situations. I am also aware of the openSER forum.

Thanks in advance.

I use asterisk’s external notify option and sipsak to send out the notify messages to trigger the mwi on my sip phones.
