Routing Combinations

The following table describes various routing combinations between servers and what to expect for each combination.

Called Address	Calling Address	Line Group	ID Method	Comments
blank	blank or string	blank	any	Invalid—you cannot have a blank called address and a blank line group at the same time.
blank or string	string	blank or string	Calling Address	Invalid—you cannot indicate to place the ID information in the calling address field and specify a calling address at the same time.
blank	blank or string	string	RLT	Invalid—you cannot RLT a call when placing the inter-server call over a tie line.
string	blank or string	blank or string	Called Address	Invalid—you cannot indicate to place the ID information in the called address field and specify a called address at the same time. Note: In 2.3+, this method is valid if the called address as entered or after going through the Dial Plan (depending on whether the line group is supplied) is a SIP address. In that case, the Interaction ID information is placed in the attribute information of the extended place call tool.
blank	blank or string	string	Called Address	Only use when you have a dedicated T1/E1 or ISDN tie line between servers. The Interaction ID information is placed directly in the dial string of the extended place call tool. If the tie line is not ISDN, you must have the ANI/DNIS configuration set correctly for the interface on both IC servers.
blank	blank	string	Calling Address	Only use when you have a dedicated T1/E1 or ISDN tie line between servers. The Interaction ID information is placed in the origination information of the extended place call tool. If the tie line is not ISDN, you must have the ANI/DNIS configuration set correctly for the interface on both IC servers.
blank	blank	string	DTMF	Only use when you have a dedicated T1/E1 or ISDN tie line between servers. The Interaction ID information plays as tones after all the following happen: Call connects Two seconds pass "91" digits play Customize the IVR on the remote IC server to call the subroutine DirectorMs_ReceiveDtmfSubr upon receiving "91." For more information, see Handler Change Required for T1 Tie Lines.
blank	string	string	DTMF	Only use when you have a dedicated T1/E1 or ISDN tie line between servers. The Interaction ID information plays as tones after all the following happen: Call connects Two seconds pass No digits play to navigate the IVR. Customize the IVR on the remote IC server to call the subroutine DirectorMs_ReceiveDtmfSubr based receiving the value in the calling information as the ANI. If the tie line is not ISDN, configure the ANI/DNIS correctly for the interface on both IC servers.
string	blank	blank	Calling Address	The dial plan determines the actual dial string and line group on which to place the outgoing call. The Interaction ID information is placed in the origination information of the extended place call tool.
string	blank or string	blank	RLT	This combination is only valid for 2.3+ IC servers using SIP. The dial plan determines the actual dial string and line group on which to place the outgoing call. The RLT specification is only a request to RLT. The call is Release Link Transferred if possible, meaning that if it is not possible (because of the carrier or other factors on the IC server) and it is otherwise successful, the call is tromboned. The Interaction ID information is placed in the attribute information of the extended place call tool.

string	blank	string	Calling Address	The call goes out on the specified line group and doesn't use the dial plan. The string in the called address field passes unaltered to the extended place call tool. The Interaction ID information is placed in the origination information of the extended place call tool.
