Known Affected Releases
Symptom: PSTN ----- T1 PRI --- 2911 GW ---- h323 ---- CUCM --- Ip phone In a scenario when the gateway receives two successive OLCs with the same mutlicast MOH address the gateway stops streaming MOH from the flash. When the first OLC comes to the gateway it streams multicast moh. Then for example if the caller transfers to a directed-park number in CUCM another OLC comes to the gateway with the same multicast ip address. The gateway should continue streaming MMOH. However no further moh is streamed and the PSTN user hears dead air. Conditions: This symptom is observed in Cisco IOS Releases 15.1(4)M6, 15.1(4)M7, 15.2(4)M5, and 15.3(3)M.
