Hello, all, As I know, the caller ID show on the telephone is usually obtained from the >From or Contact header field. Is there other field/way that we can obtain the caller ID?
I would like to know this, because I have an argument with someone about the caller ID. The scenario is a user makes a call from Mobile phone to an UA. (The UA uses the information from From header field to show the caller ID) The telephone which is connected to the UA is not able to show the caller ID, and I find that both From and Contact header field(INVITE packet sends from sip server) of the call contains "anonymous" instead of mobile phone number, I think this is the reason why the telephone cannot show the caller ID. Although I don't know why the INVITE packet from sip server is not able to contain the mobile phone number, I think this problem is not caused by the UA. Am I correct about this? Please advice. Thanks a lot! Best Regards, River _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
