We have 8 analog lines, 40 extensions and the system is in hybrid mode. We have a long distance and international calling on all the lines. The cost is very less if we dial "1019898" number first and then the international number. So, my company want to block the direct dialling of long distance calls but it should be able to dial out if the person first dials out "1019898" and then the long distance number.
Can you please suggest me how can I implement this?
