Could you teach me minimum required Asterisk modules, application and etc to install PSTN GW+SIP Client functionalities in a PC as shown below? I have already downloaded astersik-18.104.22.168 and dahdi-linux-complete-22.214.171.124+2.4.1 in the PC.
Analog telephone — PSTN GW + SIP Client — SIP Server
Since available memory in the PC is very low, I have to select minimum requirements on screen “Asterisk Module and Build Option Selection” diplayed by executing make menuselect on console. First, I have selected chan_dahdi, chan_local and chan_sip as Channel Drivers on the screen, but don’t understand that what are required in Applications, Resource Modules and etc on it to satisfy the above functionalities.
