I have successfully installed Asterisk 1.4 and DAHDI for Pri card and i want to used Digium pri card for outbound calls from my internal ip phones using G.729 and G.723 ,
my question is do I need to install these codecs or licence ?
i dont want any codec conversion just for dialout from ip phone to pstn using PRI provided by local teleco…
Sorry i didnt explain in detail, internal mean intranet which is in different cities connected ovr IP VPN, and PRI in only headoffice so i need to use these codecs for calling out on PSTN from headoffice where Astersik is installed,
Intranet —> Asterisk (HO) —> PSTN (PRI)
just install the codec or lic too, if euro isdn (30 channels) mean 30 lic to purchase ?
