I am a new asterisks user. I would like to build an Asterisks VOIP GW (ISUP to SIP) with a TE820 card (8 E1 = 240 simultaneous calls). What is the minimum PC hardware configuration (CPU, RAM) you would recommand for this ? My traffic profil is the following : call average duration : 240s, 1 call attemps per seconds. In addition what would be the addition requirement if I run on this PC G711 to G729 transcoding for all calls through two TC400B cards?
Thanks a lot for your support,
