Example 1: Slave signaling and payload to HG 3500.
Example
2: DMC signaling between HG 3500 (SIP subscriber) and HG 3500 (Trunk),
e2epc between SIP subscriber and HG 3500.
SIP subscriber A sets up a call to OpenScape 4000 A. OpenScape 4000
A routes the call via a trunking connection to OpenScape 4000 B. OpenScape
4000 B then sets up a connection to TDM subscriber B. OpenScape 4000
B initiates a DMC between HG 3500 in OpenScape 4000 B and the HG 3500
in OpenScape 4000 A. OpenScape 4000 A ensures that an end-to-end payload
connection (e2epc) is established between SIP subscriber A and the HG
3500 in OpenScape 4000 B.
