sorry 4 to 11 is an another problem about dialing, no iclid,
i see exactly the same problem only 4 digits shown on the iclid , when i upgrade one 3.1.56
system to 3.2.53, i can't solve the problem, roll back to 3.1.56.
i think we should export settings , delete conf and upgrade the unit, end import settings to ipoffice, or rewrite the ipo config from zero.
