caller ID do not display on analog phones

[abdulkarim041]

Hi,

in my scenario IP phones are registered to CUCM and analog phones are registered to ISR4331 router. it's one single network.

 I have configured the following commands under the analog FXS port

station name A. sample

 station number xxxxxx

 caller-id enable

analog phones dont show the caller ID's whenever they receive the call from IP or from analog phones.

only IP phones show the caller ids whenever they receive the call from other IP phones.

is there any way to show the calling id of calls on analog phones?

Are the FXS ports MGCP or SCCP? If MGCP, CUCM needs to be on 8.x or newer, although hopefully you’re running a much newer build than that at this point.

Does the CNAM data arrive in the initial call setup to CUCM or in a subsequent facility/update message? The CNAM FSK data is transmitted between the first and second ring; if CUCM doesn’t have it by then there is no subsequent update mechanism as there is for IP Phones.

Thank you so much.

SIP trunk have been configured between ISR router and CUCM. Phones are locally provisioned at router. no MGCP/SCCP have  been configured. 

Yet I did not check the  the CNAM.
