Example #1 – Basic TDM to/from VoIP
System Configuration:
Central Office PBX Gateway
Media
Server
T1 T1 WAN
. . .
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.
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”. There is no
corresponding “All VoIP Requests” host group since VoIP host groups are not used for
inbound VoIP matching.
2. Set up TDM Trunk Groups.
Name Selection Direction Selection Mode Port/Channel Content
all TDM requests (1) (2) (2) * (3)
any TDM channel Ascending (4) Cyclic (4) *
Notes:
1. The name of the group is your choice but it must be unique within the trunk group set.
2. Selection Direction and Selection Mode are only used for outbound TDM requests. Since
this is an inbound group they are don’t care.
3. An asterisk specifies all ports and channels.
4. If there are problems, Cyclic and Ascending are fairly easy to debug. So use them unless
there are overriding site requirements.
3. Set up VoIP Host Groups.
