"This problem may occur when an IP phone user blind transfers a call to another destination (another IP phone, IVR, IPCC queue, etc). The transfer request triggers the Cisco Unified Communications Manager (CUCM) server to send an H.225 INFORMATION message with a Signal IE to the Cisco IOS H.323 gateway indicating to start/stop playing ringback tone toward the PSTN. The Cisco IOS H.323 gateway should generate the ringback tone, but it should NOT send the Q.931 INFORMATION message toward the connected service provider switch. "
