Incoming call - transfer to outgoing trunk to ip gateway 1

[kraftsha]

I have an issue with an external call coming in, hitting the udp table and getting routed over another trunk to our IP Media Gateway.

Incoming Trunk COR 33 FRL 2
IP Gateway Trunk COR 34 FRL 0

Entry for UDP table is 3300 goes to aarcode 266.
266 goes over route 17 to trunk group 2 FRL 7.
Trunk group 2 has COR 34 has FRL 0.

These FRLs are so confusing. Can someone straighten me out?

In systems where "Authorization Codes Enabled? y" on the system-parameters features, the descriptions below will not return a busy but a recall dial-tone so that an Authorization Code can be used to override the programmed originator's FRL.

When you dial an authorization code, the Facilities Restriction Level (FRL) that is assigned to the extension, the attendant console, the incoming trunk group, or the remote access trunk group that is in use for the call is replaced by the FRL assigned to the authorization code. The FRL that is assigned to the authorization code functions in the same way as the original FRL.

However, the new FRL that is assigned to the authorization code might represent greater or lesser calling privileges than the original FRL. Access to any given facility depends on the restrictions that are associated with the FRL of the authorization code.
--------------------------------------------------------------------------------
The originator's COR will determine what types of calls you are allowed to make.

If an agent logs onto a phone, the COR of the Agent ID, not the COR of the station, is what determines the calling authority.

The FRL on the originator's COR must be equal to or greater than the FRL of the outgoing route pattern or facilities in order to complete the call.
Note: the originator can also be a trunk (facility) and the FRL of the trunk-group's COR will be used. This is also known an incoming trunk to outgoing trunk call

If the originator's FRL is a 3, calls to facilities with FRL 3 or lower will be allowed. An originator CAN make calls on route patterns or facilities that have an FRL of 3, 2, 1, or 0 (the same as the originator's FRL or LOWER).

If the originator's FRL is a 3, calls to facilities with FRL 4 or higher will be denied. An originator CANNOT make calls on route patterns or facilities that have an FRL of 4, 5, 6, or 7 without Authorization Codes Enabled? y and the used Authorization code having a equal to or higher FRL than the originator's FRL, or someone with a higher FRL making the call for them.

If the FRL of the outgoing facility is MORE restrictive (higher) than originator's FRL, the call would be denied.

If the FRL of the outgoing facility is equal or LESS restrictive (lower) than originator's FRL, the call would be allowed.

This is one way of controlling International outbound calling (The Most Expensive Long Distance).
--------------------------------------------------------------------------------
Examples below are all originating a call to a route pattern or outgoing facilities (trunk-group via TAC)

outgoing call from station 1001 - COR 1 with FRL 4
incoming call on trunk-group 1  - COR 1 with FRL 4
remote access barrier code 1234 - COR 1 with FRL 4

If originator's COR with FRL of 4, CAN make calls on all route patterns and facilities with CORs that have FRLs 0 - 4

CAN make 911 call on route patterns and facilities with FRL of 0, 1, 2, 3, 4
NOTE: you will never want to restrict 911 and 9911 for legal reasons

CANNOT make (local calls on route pattern and facilities)with FRL 5 or higher
CANNOT make (LD calls on route pattern and facilities) with FRL 6 or higher
CANNOT make (International LD calls on route pattern and facilities) with FRL 7

If originator's COR with FRL of 7, CAN make calls on all route patterns and facilities with CORs that have FRLs 0 - 7 (UNRESTRICTED)

to allow 911
make the station's COR use an FRL 0

to allow 911, local
make the station's COR use an FRL 5

to allow 911, local, non-International LD
make the station's COR use an FRL 6

to allow 911, local, non-International LD, International LD
make the station's COR use an FRL 7[\code]

Thank you very much.

I changed the frl of the outgoing trunk to match the frl of the incoming trunk and that resolved the issue.

Thanks again!

Glad to help. Hope that cleared up the FRL confusion.
