Because of the heavy load and the high expectations of an asterisk server offered as a solution integrated with our CRM software, we were looking into other possibilities than software Licenses for G729 and G723 codecs. To lower the pressure on the processor giving it more space to do more work. We heard of a hardware (PCI CARDS) can be used with Asterisk that does the work. And we stumbled with Digium TC400B.
Could be a newbie’s question.. but does that serve our needs? As we have not pressured a server before up to 1400 extensions with 600 outbound SIP calls (customer’s needs). The server in question is Core I7 16 GB ram and Raid 10 SAS drives. We need to know how many calls with G729 or G723 can this server handle? And as far as we can see this Digium TC400B card can be a cheaper solution If calculating the CPU cost plus the licenses for each channel. One more question.. can we add two of those cards to the server? Will it be efficient?
