[Freeswitch-users] SIP phone displays b_callee_name and b_callee_num on outgoing calls

Hello. Help me please. When I try to dial from Cisco SPA504G SIP phone via FS, after successful connection I see on screen "Outbound Call" and number@ip, which are values of variables b_callee_name and b_callee_num. I've never seen something like that on any other PBX (Asterisk, Yate, proprietary solutions). How to disable this behavior? It's not only confusing, it prevents me from simple redial lasy dialed number by respective button, as SIP phone tries to dial to that b_callee_num, which is in some different format.
