I want to query the IP address of a registered phone using its extension. Is there a generic way for all PBXs. I know I can use CLI for Asterisk but I don't know if there is a way for Cisco Call Manager. If a generic way is available, I want to know. Maybe there may be a way to query all of the SIP phones on a network and get their IP Adress-extension mappings or maybe there is a SIP request or trick for it or some other way.
If there is not a generic way, can you help me for Cisco Call Manager case.
All I want to know is IP-extension mapping in some way, I don't care about the method.
Thanks for your help.
