CUBE error 400

[j.huizinga]

Hi,

We have a CUBE and we have a problem when we receive an INVITE the CUBE responds with error 400 Bad Request

When I did a "debug ccsip all"  It seems the CUBE has problems with some options in the SDP. The SDP has these two options:

b=RS:375
b=RR:1125

In the debug there is the line:

/SIP/Info/sipSPIProcessDiversionHeader: No diversion headers recvd from app container SIP: Error: BW Modifier type unsupported (RS)

How can we change the CUBE to ignore these bandwidth modifiers?

Thanks

Hi @j.huizinga

Do you have configured CAC (call admission control) on your CUBE?

[j.huizinga]

Hi,

No CAC configured at all, no where. Not needed.

I would like the CUBE to ignore these SDP options

Ok @j.huizinga

Perhaps you don't need that at all but as I concerned CAC config on my CUBE gave me that issue.

That's the reason why I ask you that.

Is it an INVITE from an ISP ?

Can you share the log please ?

Hi,

I try to attach the log file but get the error:

The contents of the attachment doesn't match its file type.

Just a simple txt file

Any idea?

Yeah, looks like we don't support bandwidth modifiers, at least on the 12.X IOS which is what you are running I believe. "b" param is supported but not the RS within it.
Upgrade to 15.X not sure what router it is. But upgrade it to the latest.

Hi,

Could be an IOS

I shall upgrade to some higher version

It is a 2811, so only the first IOS 15 is supported if I am correct

Thanks

That's right. Highest that you can upgrade is 15.1. Upgrade to the latest on that train which I believe is M10.
