1 Overview 1.1 Test Purpose This test aims to check whether the basic call functions and other services between IP phones deployed on the Cisco CUCM and plain old telephone service (POTS) and IP phones deployed on the espace U1930 run properly when the espace U1930 and Cisco CUCM are connected through the Simple Internet Protocol (SIP) trunk. This test helps facilitate the compatibility between the espace U1930 and Cisco CUCM and provides references for future networking or test. In this test, the espace U1930 V100R001C01SPC600 is used to connect to the Cisco CUCM. A patch can be installed to resolve the problems found in the test, and the problems must also be submitted to the espace U1930 V100R001C02 for fault rectification. 1.2 Test Scope This test checked whether the call functions and basic supplementary services such as call hold, meeting, call transfer, and call restriction run properly between the espace U1930 and Cisco CUCM that are connected through the SIP trunk. A patch was developed to rectify faults found in the test. 1.3 Test Location Lab 509, Floor 1, Dongguan Technological Park, Huawei Hangzhou Research Institute. 1.4 Test Duration First round of test: from December 10, 2012 to December 17, 2012 Second round of test: from January 21, 2013 to January 24, 2013 1.5 Test Engineers No. Name Company Remarks 1 Liu Shanshan isoftstone 2 Test Environment 2.1 Device Information Table 2-1 Device list No. Company Device Name Device Model Device Quantity Software Version 1 Huawei U19XX U1930 1 V100R001C01S PC600 2 Huawei IP Phone espace7850 2 2.60.94.101 3 Cisco Cisco Server CUCM 1 8.6.1.10000-43 2013-05-09 Huawei confidential.

Statistics Planned Number of Test Actual Number of Test Number of OK Number of POK Number of NG Number of NT Number of Test That Does Not Need to Be Tested Business Trunking Test All Test 76 76 67 5 4 0 0 76 76 76 76 76 0 0 Percentage 100% 100% 88% 7% 5% 0% 0% This test aims to find problems, develop the corresponding patch, and verify the patch. Before the patch was developed, only basic call functions and other simple services can be tested. After the patch was installed, faults of the VU and name identification presentation functions were rectified. However, the patch failed to rectify the faults of functions such as simultaneous ringing, sequential ringing, and ONLY that are related to POTS users and the problems are to be resolved in the later version. The patch is applicable to the espace U1930 V100R001C01SPC600B012. For the release version, a new patch must be developed and released at http://support.huawei.com. Name of the patch used in the test: U1930_SPC600B012_Cisco Resolved issues: A Cisco user dials the meeting access code and automatically releases the call. Currently, Cisco users can dial the VU and virtual machine specification (VMS) prefix. When a Cisco user calls an espace U1930 user whose user name has been specified, the Cisco user hears the RBT, and the phone displays a message indicating that the Cisco user has dialed the wrong number. After software parameter 2833 is enabled on the Cisco CUCM side, 2833 is not contained in 200 OK returned by the espace U1930, which causes the dialing failure of the Cisco phone. 5 Known Issues Table 5-1 lists the issues resolved by the installed patch. Table 5-1 Resolved issues No. Issue Solution 1 When the G723 codec mode is enabled, the third-party user automatically releases the call after the SIP user performs press hookflash. Change the codec mode of the espace U1930 and SIP phones to G711u. 2013-05-09 Huawei confidential. No spreading without permission. Page 12 of 13

Table 5-2 lists the known issues and causes. Table 5-2 Known issues No. Issue Cause 1 When a Cisco user calls a SIP user assigned the simultaneous ringing or ONLY right, the phone of the POTS user who has enabled the simultaneous ringing service does not ring. 2 A Cisco user dials the ONLY numbers of the espace U1930 (primary number: phone number of the POTS user; secondary number: phone number of the SIP user), and when the SIP user picks up the phone, the Cisco user keeps hearing the RTB. 3 The SIP or POTS users cannot access the CBB and CCNR services when receiving calls from Cisco users. The error occurs because the Invite message sent by the Cisco CUCM does not carry any media streams. The problem is submitted for rectification in the later version.
