ISCC Call Overflow Flashcards
inbound-only
Call Overflow Parameters that the T-server send queries to match inbound calls or any call type. If Call attribute is not inbound and it set to true then it will exclude inbound calls. Determine what type of calls ISCC COF queries should be sent.
match-callid
Call Overflow Parameters that instruct T-server to send queries to match calls by network call id on switch type that support it and include the parameter. Determine what type of calls ISCC COF queries should be sent.
match-ani
Call Overflow Parameters that tells the T-Server to sends queries to match calls by ani. Determine what type of calls ISCC COF queries should be sent.
cof-feature
Enables call over flow on T-server
cof-in
Resource Type: Matches calls only when access resources(DN) have this configured as their type.
cof-not-in
Resource Type: Excludes call arriving on DN with cof-not-in configured.
ISSCRequestGetCallInfo
Request sent to remote T-server(originator) to verify if the call overflowed there once the call has arrived on Dest. Switch. (Call Matching Step 1)
ISSCEventCallInfo
If the request was successful the remote T-Server will send the Call Data to the requesting T-Sever. The T-server at the destination will update the data(ConnID, CallType UserData, and CallHistory)
(Call Matching Step 2). Distribute all suspended event related to the call and deleted transaction information.
ISSCEventCallDeleted
Once the call has ended on the original switch it will alert the T-server which sends out the event messages the call has been release and will be deleted from memory. (Call Matching Step 3)
How does the ISCC determine the location of the original T-Server to send ISCCRequestGetCallInfo after call arrives?
The T-server checks the call once the it is alerted by the switch via CTI of the call arrival. ISCC will attempt to match the call type, ANI, CallID, or OtherDN attribute after checking the call attribute and the switch type and switch access code. The ISSC will query connected T-server(remote) on whether they have the matching call. The remote Switch Access Code must have these overflow parameter configured corresponding to the attribute.
COF Switch Support for attribute type
All switches support Ani/Other DN matching because the switch sends data through the PSTN for call transfer. Only a few switches network call ID.
Create a COF DN
Create a object under the switch with a DN number, type = Access Resource, and Advanced tab Resource Type = cof in or cof not in
How are Switch Access Code Configured?
Switch Access Code are configured in Outbound Interaction. The Access code in the original switch will have remote switch as the destination.
What is Call Overflow
Passive external routing where when the call arrives at the destination switch call matching will be performed. The attribute of the call will be checked(Network CallID or Ani/Other DN) and ISCC will query the remote destination for the matching call to get the call data.
