SUMMARY

Cisco Unified Communications Manager (CUCM), version 7

Test cases in nearly all areas passed successfully with regard to both Ascom platforms. It was, furthermore, noted that Cisco has removed support for registration without digest authentication (instance-id) when it comes to third-party SIP devices.

The following guides: ”Configuration Notes for Cisco Call Manager in Ascom VoWiFi System” (TD 92437GB)and “Configuration Notes for Cisco Call Manager in Ascom IP-DECTSystem” (TD 92424GB)are, in most aspects, still relevant today.Queries about licensing should be directed to Cisco.

Pleasealso see“Appendix A: Test Configurations” for further details.

General Conclusions

Ascom interoperability verification produced, with few exceptions, good results towards Cisco Unified Communications Manager (CUCM), version 7.

IP-DECT and VoWiFi handsets were configured to register at the CUCMwith their endpoint numbers and to provide DTMF signalling through RTP(RFC2833). The codec of choice for these tests was G.711U, with a packet interval of 20ms, while the “Hold Type” was left at its default setting, namely “inactive”. Furthermore, the option “Hold on Transfer” had to be enabled on both the IP-DECT Base Station (IPBS) and Ascom i75 handset for attended transfers to pass test cases successfully. The latter platform also required local Music-on-Hold (MoH) and Call Forwarding (CDIV) to be enabled on handsets.Parameter settings are elaborated upon in the “Test Results” section for respective platformlater on.

Basic Call, brokering/enquiry, (un)attended transfers, Call Diversion (CDIV) and Message Waiting Indication (MWI) passed,in the case of IP-DECT, most scenarios. It should be emphasised that Call Waiting (CW), Do-not-Disturb (DND), CDIV and MWI were tested with Supplementary Services enabledon the IP-DECT base station (IPBS).On page 10, one will find a screen shot of suggested IPBS settings for Supplementary Services.

The Ascom i75, however, struggled to perform as well as IP-DECT, especially in the area of transfer. One scenario involving attended transfer and two PSTN calls failed (INTOP NCR pending, not an Ascom i75 problem), while another related to unattended/“blind” transfer also failed (INTOP NCR#15670). The latter had been resolved when revisited in July 2010.

At the time of testing, CUCM did not support overlap sending (post-dial) nor, due to limitations of the license for 3rd party SIP devices, certain telephony features , e.g. MoH and feature codes/call procedures. Support for registration without digest authentication (instance-id) had also been removed in CUCM, version 7, when it comes to third-party SIP devices. Please contact Cisco for more information about their licensing model.

TEST RESULTS

Ascom IP PBX Integration- VoWiFi

Software Versions:

• Cisco Unified Communications Manager, v 7.1.3-30000-1
• Cisco Aironet 1240AG, v 12.3(8) JEA
• Ascom i75, v 1.7.10

Signaling Protocol:

• SIP

CUCM:

• Settings per ”Configuration Notes for Cisco Call Manager in Ascom VoWiFi System” (TD 92437GB)
• Caller Line Identities(CLI) require additional configuration
• CUCM license for “Third-party SIP device” implies some limitations, e.g. no Music-on-Hold (MoH), lack of telephony features configurable from the handset etc.

Ascom i75:

• “Endpoint Number” and “SIP Proxy Password” correspond toUser ID and Password
• Default SIP settings except:“Local Call Forwarding” “Hold on Transfer” enabled

SIP Settings

Soft Key for Call Diversion/Call Forwarding

Please refer to appendix A for more information regarding device configuration.

Known Issue(s):

• Internal andPSTN calls stay connected when battery is removed from Ascom i75 during call (PBX-dependent issue)
• Local Call Forwarding on Busy (CFB) only works if INVITE is forwarded to Ascom i75 (per design, PBX-dependent issue)
• A and C party hangs up after attended transfer by Ascom i75 (not an Ascom i75 issue)

Test Areas

Basic Call, DTMF: 100% pass (15/15)

• CNIP/CONP OK, requires CUCM configuration
• DTMF OK
• Overlap sending (post-dial) not supported by IP PBX

Basic Call, Portable Unavailable: 50 % pass(3/6)

• Three test cases related to battery being removed during conversationNOK (#5107.2, #5108.1, #5108.2)

Procedure Mapping: N/A

• Feature codes not supported by IP PBX, partly due limitation of CUCM license

Three-party Services: 89% pass (24/27)

• Attended transfers requires “Hold on Transfer” enabled
• One test case related to attended transfer NOK (#5115.3), not an Ascom i75 issue
• One test case related to unattended/”blind” transfer NOK (#5116.1), problem resolved when revisited in July 2010
• No MoH, limitation of CUCM license

Call Diversion: 57% pass (4/7)

• Call diversion supported through “Local Call Forwarding”, requires handset to be switched on and in coverage
• Two test cases related to Call Forwarding on Busy (CFB) NOK (#5126.2, #5126.3)
• Feature codes not supported by IP PBX, partly due limitation of CUCM license

Telephony Feature: 100% pass (2/2)

• MWI OK, simulated by IP PBX
• Limited testing due to lack of 3rd party competence

Please keep in mind that metrics do NOT account for untested cases.
