. . .
Requirements:
Routing Requirements:
1. All inbound TDM calls must be routed to the media server (IP address 172.13.4.3).
2. All inbound VoIP calls must be routed out the TDM. Any available TDM channel can be used.
CPID manipulation Requirements:
Inbound VoIP calls:
• The VoIP calls use E.164 format. We must translate from E.164 to format acceptable by a
T1 line.
• Calling & Called Numbers of the form +1YYYxxxxxxx (where YYY is the area code and
xxxxxxx is the phone number) must be changed to 91YYYxxxxxxx.
• Calling & Called Number of the form +ZZxxxxxxxx (where ZZ is the country code and
xxxxxxxx is the phone number) must be changed to 9011ZZxxxxxxxx.
Inbound TDM calls:
• We must translate from the T1 format to E.164.
• Calling & Called Number of the form YYYxxxxxxx must be changed to +YYYxxxxxxx.
• Calling & Called Number of the form ZZxxxxxxxx must be changed to +ZZxxxxxxxx.
Steps:
1. Determine the required TDM Trunk Groups and the VoIP Host Groups.
• From requirement #1 we have a TDM trunk group of “all TDM requests” and a VoIP host
group of “172.13.4.3”.
• From requirement #2 we have a TDM trunk group of “any TDM channel”.
2. Set up TDM Trunk Groups.
