[cisco-voip] Cisco ASA and Skinny

[Chris Ward (chrward)]

You will need to make sure your version of ASA code supports the version
of SCCP is running. Generally speaking, for this scenario, the later the
ASA version, the better.

This basically says that ASA 8.3.1 added support for SCCP version 19
which is what UCM 8.0 uses with its default phone loads now I believe
(depending on the phone model).

I'm trying to configure my ASA firewall to inspect Skinny traffic so
that it will open RTP ports as required.

 

 

I have allowed port 2000 to my call manger from the phone.

 

Under service policy I have configure Protocol inspection for Skinny.

 

When I place a call the both ends ring but as soon as the call is
answer, I get loads of RTP packets drops and obviously no audio.

 

 

Can anyone please advise what I'm doing wrong.?
