We have Cisco CM Version 11, Cisco 9971 and Icon 600 and other VC equipment in our network,  We have problem when we communicate by SIP calls between Icon 600 and Cisco 9971  IP Phone  through Cisco CM, Cisco 9971 didn't receive picture from icon 600 but Cisco 9971 picture shown on Icon 600,  We don't have problem with other device like Express series and other brand devices. any suggestions?
