Hi All,

I'd lie to ask the difference between these two modules and get opinion about their use cases.

I saw several configuration examples of Kamailio that use RTPProxy. Is it necessary to use RTPProxy? 

(scenario: public network ---> behind the Kamailio I have FreeSwitch). Clients are behind of NAT & firewall

Any thoughts, tips, tricks would be much appreciated.

Regards,

Angel
