Goal
Does SBC allow multiple to-tags within same SIP call flow to caller when call forking?
In case of sip recursion call flow, kind of a serial forking on core side of SBC. After SBC receives provisional response (180/183) from outbound session-agent, followed by 503 which triggers SBC to go to next hop agent in a Session-agent group.
SBC changes the `TO' tag in dialog between itself and the caller whenever it forwards provisioning responses (180/183) to the caller from each SA.
