I Hope I explain this right, and as a disclaimer i am really new at this.
I am attempting to setup an ACL on my Cisco Router to allow SIP telephone connectivity to my Asterisk server. In addition i will be setting up some asterisk connectivity with my SIP provider.
Specifically i need to know what ports i need to allow inbound as well as outbound to allow this type of connectivity. ( I hope this does not vary from vendor to vendor.)
My SIP provider simply says i need ports 5060-5061 as well as 10000-20000 but does not specify UDP or TCP nor does it specify inbound outbound or both.
Also, I really am not sure what i need in order for my phones out on the internet to get back to my server.
Any Information would be greatly appreciated.
