Hey, guys. I'm doing compression in VoIP. I just need to care about IPv4 and ignore IPv6. I want to know whether I should use list compression?

Hello,

I'm not sure that I fully understand your question... You do not choose to use or not to use list compression. The library takes that decision depending on the streams you compress. For one IPv4/UDP/RTP, list compression is not used by the RTP profile.

Didier

Thank you! I just need to compress IPv6/UDP/RTP streams.

Hello,

You said "I just need to care about IPv4 and ignore IPv6" in the first message and "I just need to compress IPv6/UDP/RTP streams" in the second one. Did you mean IPv4/UDP/RTP in your second message?

Regards,
Didier

Ohm. I'm sorry. It's IPV4/UDP/RTP. Thank you.
