Description

---

Seems the jigasi doesn't recalculate the authorization header when it hangup the call.

Current behavior

---

When I try to hang up it, the jigasi send BYE to PBX, in the Proxy-Authorization, it still using the same "response" value as the INVITE.

Expected Behavior

---

As the RFC3261, section 22.1: For BYE, you should recalculate the authorization header since the method is changed.

So we will need recalculate the "response" when sending the BYE, shouldn't use the same response as the INVITE.

Possible Solution
