Laurentius26 ROMS have Automatic Call recording, check out latest rom releases here : http://www.laurentius26.net

the call recording software they're using in their rom is called "call ACR"

i downloaded the latest rom on laurentius26 ( LEOV3.4_GoldEdition_2.14_Stock/Spike™_WWE_23568 ) but it seems that it dont have 2 way call recording,
any other two-way voice recording on HTC HD2?

the htc hd2 phone dont have full duplex ICR recording cappabilities, all call recording softwares will record your own voice clearely, but the other side will be recorded of the speaker directed to your own microphone

so you'll have to turn the speaker on to record the other side voice.
