We have cisco 2651 which acts as h323 gateway between CCM 3.3.3sr2 and PBX (Alcatel 4400). PBX is connected to a cisco via an E1 qsig connection.
Calling Name is not shown (only number) in both directions. But in a debug messages (debug isdn q931) I can see that IE - Facility contains some long hex (representation of the Calling Name?).
