CUBE - Modifying SIP Messages

[Simon Battye]

Hi,

I have a requirement to send SIP 404 Messages to our ITSP for calls "not found" in CUCM.

At the moment this is the call flow: 

• CUCM -> CUBE -> ITSP -> PSTN

If a call comes in from the ITSP, our CUBE queries all CUCM nodes sequentially, each CUCM node returns a 416 Unsupported URI Scheme message if the number is not know to CUCM or is not registered.

Once CUBE has queried all the CUCM nodes, it then sends a 503 Service Unavailable message back to the ITSP but i'd like it to send a 404 Not Found message instead.

Is it possible to use SIP Profiles on CUBE to manipulate/transform these outbound messages to our ITSP?

Thanks, Simon

Thanks for this documentation, really useful - I'm hoping the following command will work:

voice class sip-profiles 1

 response 503 sip-header SIP-StatusLine Modify “503 Service Unavailable” “404 Not Found"

I'll test this and confirm if it is OK.

I thinks should take care of it, there was a tool which you would have tested which is not working anymore explained in the link below.

Try i on a dial-peer which is an exact match if you are testing in production so that it does not impact anything else..
