Hi,

I use diva SoftIP-SIP with the Diva .Net API (C#).

When I make a SIP call from my softphone directly to the Diva (no registrar server,  PC-To-PC SIP Call), I get a null calling Number. The called Number is OK but not the calling number !!

I have created a phone number mapping corresponding to my softphone.

here is a SDK log :

I use the CallingName property instead of calling number, but Sometimes, I don't get the MANUFACTURER_IND infos.

I use DSAPI.GetCallInfo()  to retrieve information ('I've also tryied GetCallProperties(), not working better..)  .

Can someone tell me how to get that caller id, or the SIP address of the caller ? or the phone number from the mapping ?

Is it possible to retrieve infos from the SIP frame, like From, To, Contact, ... ?

thx.

Have you checked with Wireshark to see if the caller's number is actually presented in the SIP message?

I've catched the INVITE frame with wireshark. It seems that the caller's number doesn't appear in the SIP address (just in the name "678"). But I've got the IP address. How can I get that address with the SDK ? And in my configuration, I don't manage to retrieve caller name : Soft IP SIP 2.2, Diva Board 4BRI-8PCI V2. (While, on an other PC with no hard board, just SoftIP, I can get the name!)
