Hi Mohammad Jaffal,
"I suppose you have problem on internal call because you are not used program code 16-04 to permit call between department groups
for Caller ID problem you need to change in program code 81-01-09 try with these values 56, 59, 68, 72, 77, 82 and code 81-01-05
you can try also with command 81-01-12 caller id time detection"
That is a great advice, thanks for your help. I changed para in code 81-01-09, it's okay from 64.
