5.1.2.1 Consulting transfer business
VGW's consulting transfer service steps are as follows:
1) B dials to A, and then A is off hook, so a session is established between A and B.
2) A's hook flashes, and now A can hear a dial tone, B is on call waiting. A continues to dial
to C, so a session is established between A and C.
3) When A is on hook, a session is established between B and C.
