cRTP configuration - number of connections

[jhinton]

Hi there,

It says in the Cisco literature that by default when RTP header compression is enabled on an interface 16 cRTP headed compression connections are allowed per interface.

If I were to make a call does it consume two cRTP connections or one? If so how many voice calls can be supported in the default (16 connections) configuration, 16 or 8? I wish to support 30 concurrent voice calls across a VoIP link. I suspect I am looking at 60 cRTP connections, is this correct?

Thanks in advance

Jim

Each voip connection takes up 2 RTP connection so we count each direction as one connection. Therefore you do need 60 connections for 30 voip calls. The default as you said is 16. Hope this helps.
