SIP Header Manipulation is now Generally Available

You can now manipulate the To and From numbers within SIP INVITE messages through creating Manipulation Policies in the Console.

The expected format of phone numbers in SIP INVITE requests can sometimes differ between on-premise equipment providers and carriers. For example, some PBXs might send numbers in a format other than E.164, the format that Twilio requires. Using Manipulation Policies, you can edit the contents of To and From numbers within SIP INVITEs to comply with formatting requirements, change the callerId of a call, or meet other needs of your public infrastructure.
