I haven't seen anyone having this issue..been trying to find it,if anyone could help i would appreciate it[
Are you using the last version? Have you done a full wipe before flashing Liquid's rom?
Sorry but i have the GSM version and i have no problem with call.. Retry to flash Rom (sometimes is the best choise) or wait for the next version!!
