Advanced Gateways Options
The ability to fine-tune the network can lead to better resource usage, help reduce chances of errors, and aid in problem solving. You can configure literally hundreds of commands for a GW. You do not need to know all of them for the test, but you do need to know them for real-world applications. I will go over a few of the commands I believe are important for the GWGK exam:
GW1(config)# Voice service [voip | voatm | pots | vofr] **used to apply voice services globally***GW1(config-voi-serv)# Allow connections from-type [any |h323 | sip | pots] to to-type [any | h323 | sip | pots] ** this option under voice service command decides which VoIP connections the GW will allow. Use the No form to disallow.
