Local Gateway Supported Call Scenarios

Revised: 08/12/2010, OL-23270-01

This document describes the Local Gateway supported call scenarios in Cisco Hosted UCS. In the Hosted UCS 7.1.1 lite release, following call flows are supported:

•Outgoing PSTN Calls

•Incoming PSTN Calls

Outgoing PSTN Calls

This section has the following topics:

•Non-Emergency calls (CgPN and CdPN NOA setting)

•Non-Emergency Calls (With and Without DDI)

•Non-Emergency Calls (CLIR/CLIP)

•Non-Emergency Calls (Nat, Int, Premium, Service, Free, Loc)

•Emergency calls

Non-Emergency calls (CgPN and CdPN NOA setting)

For all of the Non-Emergency calls the CgPN and CdPN can be sent to the PSTN differently depending on how the trunk is configured to handle NOA. Therefore, following Non-Emergency outgoing PSTN calls are supported:

•CgPN NOA is set (Yes), CdPN is set (Yes)

•CgPN NOA is set (Yes), CdPN is not set (No)

•CgPN NOA is not set (No), CdPN is set (Yes)

•CgPN NOA is not set (No), CdPN is not set (No)

IP Phone -> PSTN (Any Non-Emergency PSTN Call, CdPN NOA - Yes; CgPN NOA - Yes)

In this call scenario:

•CdPN NOA is set (Yes)

•CgPN NOA is set (Yes)

•IP Phone (Internal Number: SLC1 + EXT1, for example with DDI Number: E164N1) in Location 1 on Unified CM cluster 1 (PSTN Published Number: E164N0, Unified CM ID: CPID1, Location RID: RID1) is making a Non-Emergency call, for example a National (Long-distance) call to E164N3 (Dialed number: PAP1 + NAC1 + E164N3)

Non-Emergency Calls (With and Without DDI)

For all of the above calls the CgPN is processed differently depending on whether the line has an E.164 number associated with the internal number. Therefore, following Non-Emergency outgoing PSTN calls are supported:

•User line configured with DDI,

•User line configured without DDI.

IP Phone (with DDI) -> PSTN (Any non-Emergency PSTN Call)

In this call scenario:

•CdPN NOA is for example set (Yes)

Non-Emergency Calls (CLIR/CLIP)

For all of the above calls the Presentation Indicator is setup differently depending on whether the user has made a call from a location configured as CLIR or CLIP, and whether the user has made a call using the CLIR or CLIP release code. Therefore, following Non-Emergency outgoing PSTN calls are supported:

•User dialing from a location configured as CLIR,

•User dialing from a location configured as CLIR and using CLIR release code,

•User dialing from a location configured as CLIP,

•User dialing from a location configured as CLIP and using CLIP release code.

Emergency calls

For outgoing Emergency calls:

•If the location is not configured to use the "Cisco Emergency Responder" or "DDI for Emergency" feature, the CgPN will always be replaced with the Location Emergency Published Number.

•If the location is configured to use the "Cisco Emergency Responder" feature, the CgPN number is modified to the Emergency Location Identification Number (ELIN).

•If the location is configured to use the "DDI for Emergency" feature, the CgPN will be replaced with an E.164 number of the line which originated the call (if the line is associated with an E.164 number) or with the Location Emergency Published Number (if the line is not associated with an E.164 number).

Therefore, following Emergency outgoing PSTN calls are supported:

•IP Phone -> PSTN (Emergency Call, Default handling),

•IP Phone -> PSTN (Emergency Call, Cisco ER configured),

•IP Phone (with DDI) -> PSTN (Emergency Call, "DDI for Emergency" enabled),

•IP Phone (without DDI) -> PSTN (Emergency Call, "DDI for Emergency" enabled)

For all of the above calls the Presentation Indicator is not setup differently regardless of whether the user has made a call from a location configured as CLIR or CLIP, and whether the user has made a call using the CLIR or CLIP release code.

IP Phone -> PSTN (Emergency Call, Default handling)

In this call scenario:

CdPN NOA is for example set (Yes)

CgPN NOA is for example set (Yes)

IP Phone (Internal Number: SLC1 + EXT1, for example with DDI Number: E164N1) in Location 1 on Unified CM cluster 1 (PSTN Published Number: E164N0, Unified CM ID: CPID1, Location RID: RID1, Default Emergency Call Handling) is making an Emergency call to EMER (Dialed number: EMER)
