### Description
Hello!
I'm beginner, and i have installed Kamailio Proxy SIP Server on Ubuntu 14.04.5
LTS
and using it to register many SIP Servers (Asterisk)
I have some issues:
1- When i call another extension in not ringing.
2- Sometimes ringing but when call is get answered there is no voice.
3- I need to receive inbound calls from my Trunks, but i did not know how to
make my proxy able to manage it.
4- I need to call some futures codes like (*45 & 555) but it is unable to call.
Thanks to all
