I have built many servers that could handle well over 200 TDM <-> SIP calls although I was using the T1's native ulaw codec. Top showed 50% CPU and very low load average and this was on a single core Pentium 4 3something GHZ CPU. I am sure with some of the multi-core systems that are out now, transcoding should not be an issue (except maybe H323.) You have a point about T.38 but Asterisk will have it one day and CallWeaver will most likely have it stable real soon. I am not sure what the Dialogic cards are capable of, but they are loaded with DSP chips. I understand that these work with ABE (or at least there are plans for this). Besides, who wants to pay all that money for what is essentially a 250mhz pc?
