[cisco-voip] Cisco ASA and Skinny

[Martin Bufton]

Chris,

 

Thanks for your reply.

 

I am running 7.2(4) on my ASA firewall can't upgrade this due to company
requirements.

 

I can't find what version of SCCP this supports.

 

I am running a CUCM 7.0.2.

 

I appears that the version of SCCP used depends on the firmware on the
phone but I can't find which firmware uses which SCCP version.

 

Do you have a link to a cross reference table?

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.?
