Provider is sending the Calling number which is 115452047 and called number is 143

so CME would get this and just send it to extension 143 ... in this call did you face the issue of unknown number ?

Dear  Nashaatmusa,

caller-id alerting Ring 2

[Nashaatmusa · Accepted solution]

Well most of the providers have issues when it comes to this command, they can't answer on what ring they are sending the Caller ID .

This command :
Use this setting if your telephone service provider specifies it to provide caller ID alerting (display) after the second ring. This setting is used in Australia, where the caller ID information is sent following two short rings (double-pulse ring).

anyway good to know that the issue is resolved now ^_^ , have a good day
