i have 6 isdn BRI telephones here. my problem is, that there are different wishes from the people who are on the telephones. person 1 wants for example the external CID number 123456 15 and person 2 the external CID Number 123456 20 and the third one wants to telephone with CID Number unknown. Now i have to Set the CID Numbers dependent from the MSN from the isdn telephone. Is this possible?
