The system is MIFM600. Incoming calls show up to 10 digits only. For incoming id with more than 10 digits i can not see the last digits and so can not return missed calls.
Is there a way of showing all digits or may be strippig some leading digits to accomodate the remaining digits.
thanx in advance

I am on PSTN, SIP and GSM
PSTN lines- These are fine because they are less than 10 digits.
But GSM and SIP lines are 12-14 digits long and international calls are up to 16 digits.Format from service provider(SP) is +xxx(country code) yyyy(area or SP code) number(6 digits or more)
thanx

I now have a clearer picture.
Incoming call to LCOB trunk port only first 10 digits displayed.
Incoming call to VOIM trunk ports all digits displayed.
What do you need/program on LCOB to display all digits?
