Can we convert 486 Busy Here to CANCEL

[voipeee]

Hi Experts,

I have a requirement wherein I need to convert 486 Busy Here response received from Provider on CUBE to CANCEL which needs to be sent to CUCM.

This is the response I receive from Provider:

Received:
SIP/2.0 486 Busy Here
From: "My Phone"<sip:1234@10.45.9.1>;tag=99BF86D7-17AA

Call-ID: 64BF4C6E-C8EF11EB-8FADA592-57678AD@10.4.9.106

Via: SIP/2.0/UDP 10.4.9.106:5060;branch=z9hG4bK5AFD1962

Please let me know if that is possible also if some can help me with SIP Profile as well

Start by posting the part of the SIP dialogue that you would want to modify as this would make it much easier for anyone to help you with this. Also I recommend you to look at this great document. It contains much valuable information about this and other topics for voice gateways.
