!---Configuration to enable "H.323 to H.323" and "H.323 to SIP" calls between Cisco
!---CallManager-Cisco CME-Cisco Unity Express. The "allow connections h323 to h323" &
!---"allow-connections h323 to sip" enable an easy configuration on gateway without the
!---need for loopback-dn for incoming calls from Cisco CallManager or for call flow from
!---Cisco CallManager to SIP for Voice Mail.

!---Two T1 ports connected back-to-back to bridge VoIP to multicast audio bridging. This
!---is required to enable dialing into multicast. Connecting the TDM T1 port back-to-back
!---offers the possibility of using E.164 number as a conference ID, or for using the
!---multicast stream for application such as Hoot and Holler.
!---
!---Cisco CME offers 3-party conference calling and is the recommended method for a
!---small branch office, the following T1 loopback cable is not required for configuring
!---the conferencing features.
!---
!---Cisco IOS supports audio mixing of loudest three streams. The TDM back to
!---back connection enables the bridging of 23 channels of VoIP to one or
!---more multicast connections (one side with multicast configuration and the
!---other side with VoIP configuration)
!---This method provides a way to connect the standards-based VoIP call control to
!---the multicast audio streams that do not have any associated call control.
