Its a antique system compared to GSM. That's why GSM users can have more than 3 people on the line at the same time. However if I'm wrong someone who knows please tell me.

Correction, it's a software limitation, not a hardware limitation. In addition CDMA is not an antique system Even the oldest CDMA technology (IS-95) is newer than GSM. CDMA 2000 (implimented in 2000) is considerably more efficient than GSM, allowing for more calls, using limited bandwidth, while increasing call quality over GSM.
The problem is CDMA is relatively young in development & proprietary. This limits development. Unlike GSM, which has open source options. If you would like to know more information about the CDMA network & how calls are handled I an provide you with a link on how CDMA works.
