Configuring Call Routing
Working with Call-Route profiles
Outbound call routing by trunk group
If no explicit call routes are defined, the TAOS unit always routes a call to the first entry in its 
database that matches the call’s parameters and is in the same quadrant. Because default entries 
do not include trunk group specifications, this behavior can cause a call to fail when multiple 
T1 or E1 cards are installed and each card supports different trunk groups. The system always 
tries the first installed card, and does not proceed to the second card without an explicit call 
route instructing it to do so.
Note: When configuring trunk groups for the purpose of outbound call routing, you must 
specify the trunk groups both in the Call-Route profiles and in each channel subprofile of each 
network line profile.
In Figure 19-1, the system has two E1 cards installed, one in slot 5 and one in slot 16. The 
channel subprofiles of the E1 lines on the first card specify trunk groups 4, 5, 6, and 7. All 
channels on all of the E1 lines on the second card specify trunk group 8.

Phone-Number Telephone number assigned to TAOS unit network lines. For lines 
that use ISDN service, the telephone number can contain a 
subaddress, as described in “Second pass: ISDN subaddresses” on 
page 19-12.
Preferred-Source Source of a call. The address of a device in the system.
Call-Route-Type
Type of call to be routed to the device. Valid settings include the 
following:
• Any-Call-Type (any of the types listed below).
• Voice-Call-Type (voice bearer calls, which do not include 
3.1KHz audio call types or VoIP calls).
• Digital-Call-Type (general digital calls, including 3.1KHz 
audio bearer channel calls, routed to a host device).
• Trunk-Call-Type (digital calls sent to a trunk device). The 
Trunk-Call-Type setting is used for outbound call routing for 
trunk calls and trunk-to-trunk switching. 
• PHS-Call-Type (Personal Handyphone System calls).
• VoIP-Call-Type (Voice-over-IP calls).
• V110-Call-Type (digital calls recognized as containing V.110 
rate-adapted bearer channels).
