Same setting for the SNOM 821's. After dialing a number, I see "Session in Progress" along with the dialed number. After the party answers, the CID look-up is then displayed correctly. Works great!Not to bump this, but for future reference this code works fine with my Snom 870. Only downside is that it shows up after the far end answers. And sendrpid needs to be set to PAI - bug in Snom's FW I think.
