POTS lines: caller ID showing up with 01234 before number


for my client we move there POTS lines from HX6 to Asterisk and now if we call in to Asterisk it shows up 01234 before actual phone number.
where to change to display name of caller instead of 01234 in Asterisk?

Thank you in Advance.

can anyone help me on this please?

Every single Cid number shows this prefix? Sounds like a misconfig somewhere, but you could have some custom dialplan to clean it up.

Thank you for replay.
Yes , every number shows up with perfix ‘01234’ on this line.
can you guide me where to look for cnam default value ?
what do you mean by custom dial plan and where to look that please?


any help please?

Something like this in extensions_custom.conf

exten => _./01234X.,1,Noop(Entering user defined context in extensions_custom.conf)
exten => _./01234X.,n,Set(CALLERID(number)=${CALLERID(number):5})
exten => _./01234X.,n,Goto(from-trunk,${EXTEN),1)

exten => _.,1,Noop(Entering user defined context in extensions_custom.conf)
exten => _.,n,Goto(from-trunk,${EXTEN),1)

; end from-trunk-fixcid

Then set the context for your trunks to from-trunk-fixcid
