Why Lua is a good choice for Scripting call configurations in SIP servers like Kamailio and Freeswitch December 1, 2020
Programing in SIP servers enables the IP telephony provider to add complex control that is difficult to realise with simple dialplan XML and IVR menus. These are best handled by using a program that is compiled with the telecom application server and invoked by SIP requests or responses in the session. This may include using … Continue reading Why Lua is a g […]
