What is the max TTL value and hop number that Cisco TelePresence MCUs support for H.323 communication?
The TTL (Time To Live) in the IP header of outgoing H.323 messages sent by the Cisco TelePresence MCU is 64 seconds. This gives a maximum hop count of 64 (bearing in mind that some routers may decrease the remaining hop count by more than 1).
