We have installed ISR 4331K9 as Voice Gateway, with 3 FXO Cards (4 ports)
we have an issue that when someone make a call from PSTN to these FXO lines, the IP Phone displays just Nine Digits.
the Caller ID's like 06XXXXXXXX, the IP Phone displays just 6XXXXXXXX.
This is an example of my FXO port's Config :
voice-port 0/1/0cptone FRtimeouts interdigit 2connection plar opx 104impedance complex2caller-id enable
Thank you in advance for your help

Take debug voice ccapi inout, verify the caller ID telco sending.if telco is providing you caller-ID 06XXXXXXXX, Check both CUCM and gateway if any translations applied.
