Dear support team,
I am using 1861 and running "c1861-spservicesk9-mz.124-20.T.bin" IOS over it.
But i am unable to receive caller ID of the out side callers on all the IP phones.
Please note that Caller ID is activated on my PSTN line connected to the FXO. I have verified it directly with a regular phone.
I have attached the configuration for your reference, please advice at your earliest.
