[Kamailio-Users] [kamailio-users] Kamailio - Polycom Sound Point

Hello I have installed kamailio - 1.5.2 with MediaProxy. I registered 101(a)domain.com and 102(a)domain.com from * PolycomSoundPointIP-SPIP_600-UA/3.1.3.0439*. But when I look for location table into database, I show received field is NULL, while from other phone like X-Lite it shows some value in same field like sip:X.X.X.X:5061. When I call from 101 to 102 using *PolycomSoundPointIP *phone, The phone rings on the other extension but when I pick up no voice is heard, the caller phone keeps hearing the wait-for-other party. Is there any changes required into kamailio.cfg or not. ?? Thanks in advance -- Regards, Chandrakant Solanki
