How to Configure the Cisco UC500 for use with Integra Telecom SIP Solutions Overview: This document provides a reference for configuration of the Cisco UC500 IP PBX to connect to Integra Telecom SIP Trunks. The document covers a basic setup with required stepsfor interoperability with Integra Telecom only. This document assumes that Integra Telecom is not a valid selection for SIP Trunking providers in the Cisco Configuration Assistant (CCA) and that an.xml file will be used for auto-configuration. In the future this.xml file will not be required. If CCA does have the option to select Integra Telecom as a SIP Trunking provider then seek an updated version of this document. Hardware and Software: The following hardware and software were employed to test interoperability between the Cisco IP PBX and Integra. Manufacturer Model Software Version Cisco UC520 Software Pack 8.1.0 Cisco IOS 15.1(2)T3 Cisco Configuration Assistant 3.0 (CCA) MetaSwitch MetaSphere 7.2 Adtran NV3305 (1 st Generation) 11.02.00.E Tested Features: The folowing is a list of features that were tested. Feature Description Issue (if any) Basic Call Making and receiving a call between None the IP-PBX and Integra Telecom service provider with both G.711 and G.729 codec. Call Hold Placing a call in On Hold state and None retreival of the call from same station. Call Transfer Relocation of an active call from one None station to another location. Both internal and external transfers were tested. Call Forward Forwarding of calls from one station None. to another location. Both internal and external forwarding were tested. Single Number Reach Allows users to answer incoming calls to their extension on either desktop IP phone or at a remote destination. Manual IOS configuration required.* Can only send out an Owned DN for Caller ID number on call to remote destination. Remote Voicemail Notification When a voicemail is left for a user, a Manual IOS configuration required.* call is generated to a remote destination alerting the user. Fax Fax Transmission None. Both G.711 and T.38 fax are supported Page 1
*Manual IOS configuration information contained later in this guide. Network Topology: Figure 1 shows how the network was configured for interoperability testing. Figure 1: interoperability network diagram Configuration Notes: This section contains a detailed description of how the Cisco UC520 was configured for interoperability testing with Integra Telecom SIP services. Network Requirements: As in any VoIP deployment there must be adequate bandwidth to support VoIP traffic. A proper network assessement should be performed before any VoIP deployment. Assumptions: All SIP Signalling uses UDP on port 5060. SIP Signalling packets use Differentiated Services Code Point (DSCP) 24. Real-Time Transport Protocol (RTP) uses DSCP 46. Licenses: The Cisco IP PBX must be equipped with licensing to support SIP Trunks. Page 2
Cisco UC500 Configuration Summary These instruction assume that the UC500 series system is being configured starting from the base configuration the the system is shipped with. First, load up Cisco Configuration Assistant (CCA) on the PC from which configuration will be performed. This can be obtained either from the software CD that came with the UC500 or from cisco.com. Next, plug the PC into one of the PoE Ethernet ports on the UC500 and set that network interface to use DHCP. The UC500 will automatically assign an IP address. When CCA first starts up you will be presented with this popup: Page 3
On the Customer Sites tab click Add a New Site. In the resulting window you will configure the properties to connect to the UC520 Enter a Name for the UC500 system. Select Specify a Device IP Address and enter the default address of 192.168.10.1 Click Start. If a Security Certificate Alert popup appears, click Yes to accept the certificate. Next you will be prompted to provide Authentication information for the UC520. The default Username and Password are both cisco. Click Ok. Page 4
You will now start the Telephony Setup Wizard. From the Welcome screen, click next to continue. The Discovered Phones page will be shown. All connected phones will be automatically detected. Additional phones can be added manually if required. Click Next when finished. Page 5
If necessary add liceses or upgrade software from the Software Upgrade and License Management page. Click Next to continue. On the System Access screen, verify the System Host Name. Change if necessary. Enter an Admin Username and Password. Click Next to continue. Page 6
The Chose Locale page will be displayed next. Select Custom and North American-10-Digit Dial Plan Template if required in your area. Change other settings such as Time Zone to suit your installation. Click Next. On the Configure WAN Connection page chose a WAN IP Configuration Type of Static IP. Enter the IP Address, Subnet Mask, Default Gateway and DNS values as supplied by Integra. Note that the values shown are for example purposes only. Your values will differ. Click Next to continue. Page 7
Next configure your LAN settings to meet your site specific requirements. For the purposes of this guide, all values were left at defaults. Click Next. Page 8
Verify all inputs on the Networking Summary page and click Next if they are correct. If values need to be changed, click Back and modify as necessary. Click Next. Complete the Users/ Extensions information to meet your site specific requirements. These configuration options include Internal Dialing, FXS Phones, Users, IP Phones, and Hunt Groups. Images are not included as none of this configuration affects Integra SIP Trunk interoperability. Complete the Auto Attendant information to meet your site specific requirements. Images are not included as this configuration does not affect Integra SIP Trunk interoperability. Configure Trunks and Call Routing. Click Next to continue. Images are not included as this configration does not affect Integra SIP Trunk interoperability. Page 9
Once all information has been input, verify that all is correct and click Apply Configuration. The configuration will be written to the device. This may take a while. When the process is complete you will see Telephony Setup Wizard Completed Successfully!. Click Save Config and Exit Wizard. The configuration will be saved to the Cisco UC500 s startup config and the Wizard will be exitted. Page 10
You will now perform additional configuration steps through CCA. Log into CCA with the admin user name and password defined previously in the Telephony Setup Wizard. The first step is to create your SIP Trunks. Via the left-hand navigation tree select Configuration. Expand Telephony, then Ports and Trunks and then select SIP Trunks. You will need to obtain the appropriate.xml file for automatic configuration from either Integra or Cisco and save it to your PC. Note the location of the file. The.xml file contains configuration specific to interoperating with Integra s network and automates much of that configuration. From the Service Provider dropdown on the Sip Trunk tab select Add Page 11
In the resulting Add SIP Service Provider popup, browse to the location of the.xml file on your PC. Select it and click OK. New fields will now be displayed on the SIP Trunk tab. Fill in all fields with the information provided by Integra Telecom with the exception of SIP Domain Name. This will be determined by your system or network administrator and it specific to your site. Once all fields have been populated click OK. Please note that the values below are for example purposes only. Your values will be different! Page 12
A User Confirmation popup will appear. Verify that the checkbox next to Add Integra Telecom as a SIP Trunk option to Outgoing Numbers in the Dial Plan is checked and fill in the Company Main Number which will be used as default outgoing caller ID. Click OK. You should receive verification in a popup stating Configuration successfully sent to UC_520. Click OK. Now an incoming Dial Plan must be created. In the lefthand navigation pane, expand Dial Plan and select Incoming. The Incoming Dial Plan will be presented. Switch to the Direct Dialing tab. On this screen DID scan be mapped to internal extensions as well as Auto- Attendants, Groups and Operators. To map a DID to a specific extension, under Direct Dial to Internal Uer Extensions click Add. Page 13
In the resulting window enter a Description for the mapping. Select SIP Trunk from the Incoming Trunk pulldown. Enter DID Range Start and End Numbers (DID) and Internal Extension Start and Stop Numbers. Click OK when all required mapping has been setup. The window will close and you will see your mappings displayed in the Incoming Dial Plan Window. Click OK. You will receive confirmation that the configuration was successfully sent to the UC520.
