I have successfully set up a asterisk server. i have a small issue Im connecting to the internet via adsl router with a dynamic Ip address. So now i need to map port on the router to asterisk server for sip trunk and normal sip phones.
I have a three problems.
1 / What are the ports i have to map on the adsl router to asterisk server
2 / I have a dynamic IP. so it change overtime i restart my router. Is thr any solution to overcome that. Can we use DDNS for this purpose. Because static ip addresses are verry expensive my country.
3 / whr i can find the cdrs for answered calls. I tried on /var/log/asterisk/cdr-cvs/ but its empty.
