If you’re using a SIP endpoint and you’ve configured your SIP phone to send custom SIP headers starting with X-VH-, Vobiz will send these SIP headers with the HTTP request.

​
Outbound calls

For outbound calls, you can set custom SIP headers while:
  • Making an outbound call
    • Using the nested Number element of the Dial element
    • Using the nested User element of the Dial element

​
Inbound calls

For inbound calls, you need a SIP phone that allows custom SIP headers. If you have one, SIP headers that start with X-VH- will sent as HTTP requests.
