How Can I add DIDWW IP Addresses To My IP-PBX System?

You need to add entry to the SIP.CONF of the Asterisk server each time we add new IP addresses to our servers.
You can see example in our knowledgebase: How to Set Asterisk@Home/TrixBox with DIDWW DID Numbers?
SIP.CONF needs to be modified every time we add IP address (you will need to change only the name of the entry section and the “host=” parameter).
