[Freeswitch-users] Port Required to communicate with Gateway

Hi, I have installed freeswitch on a Virtual Machine, and I am not able to configure the gateway for some reason. Can someone tell me which ports are required and need to be opened on the virtual machine to communicate with Gateway in freeswitch? Since all the ports are not opened in the Virtual Machine, this could help me open up those ports and configure Gateway for freeswitch Much help is needed. It's Urgent Thanks in advance.
