This Feature is Called CallWaiting.

Could you give me more information about your setup.

Possible reasons for this problem is Codec usage.
  For Example:  Call  From PSTN is translated in gateway to G.729 codec for
example, but "Dialed Phone"  ( phone attached to CCM ) already have active
call  with G.729 codec so call will fail because most Cisco Phones does not
support second call with G.729 codec.
