[Ccrtp-devel] RTP Multicast TTL

[Tom Anwyll]

Hello RTP Gurus,

Pardon my ignorance and inexperience.

It is my understanding of multicast that the time to
live (TTL) option determines the number of times a
multicast packet will be routed beyond the network the
packets originate from.

However, I can not determine the method to set the TTL
for multicast RTP session transmitters in ccRTP.

If possible, could someone explain to me how to set
TTL in ccRTP for multicast RTP session transmitters? 

If it is not possible to set TTL in ccRTP, doesn't
this limit ccRTP for use only in local networks? How
would multicast RTP transmitted packets get routed to
multiple networks?

Thanks (in advance) for the explanation,
Tom
