Case Study 1: Registering IP Phones with a remote Call Manager Objectives • Place calls from IP Phones under R1 to IP Phones under R2 • Place calls from any IP Phone (under R1 and under R2) to the regular PSTN/POTS Phone • Place calls from the regular PSTN/POTS phone to IP Phones. Scenario The ACME Inc. has a new office at another city. In order to save money, a VoIP environment will be implemented by you. The CME Router will be located at the company’s main office.
Equipment Requirements 2 2811/2621XM; 2 Cisco IP Phones; 1 Regular Phone; 1 ADTRAN Atlas550 with a PSTN and PRI/T1 card; 2 Cisco Vlan Capable Switches; 123 - 165 IP Telephony v1.0 Case Study 1: Copyright © 2005, Cisco Systems, Inc.
1 1MFT-T1 card 1 NM-HDV Network Module; Appropriated cables and power supplies, Notes: - If using switch modules connected to the routers instead external 3550/3560 switches, check the “IPTX Appendix A - Using Switch Modules on the CME Routers” document.
headed to the PC will be be untagged (PC’s do not support tagged packets). Finally, configure the port connected to the Router as a trunk port.
Step 3 Voice CME Router Configuration 3.1 Preparing the Routers to handle the VLANs Create and configure two sub-interfaces on the fastEthernet 0/0 of R1 and two sub-interfaces on the fastEthernet 0/0 of R2. They will be used by the VLANs configured on the switch. On R1: R1(config)# int fa0/0 R1(config-if)# no ip address R1(config-if)# no shutdown R1(config)# R1(config)# R1(config)# R1(config)# int fa0/0.10 encapsulation dot1q 10 ip address 10.10.0.1 255.255.255.
On R2: R2(config)# ip dhcp pool DATA R2(dhcp-config)# network 10.20.0.0 255.255.255.0 R2(dhcp-config)# default-router 10.20.0.1 R2(config)# ip dhcp pool VOICE R2(dhcp-config)# network 10.25.0.0 255.255.255.0 R2(dhcp-config)# default-router 10.25.0.1 R2(dhcp-config)# option 150 ip 10.25.0.1 To exclude the routers ip address from the pool: On R1: R1(config)# ip dhcp excluded-address 10.10.0.1 R1(config)# ip dhcp excluded-address 10.15.0.1 On R2: R2(config)# ip dhcp excluded-address 10.20.0.
The ip source-address command specifies the address and port used by the CME software. Create the phones configuration files on the flash memory by issuing the create cnf-files. Specify the format of the dial plan to be used on internal IP Phones using the dialplanpattern command. Finally, the secondary-dialtone 9 command sets the 9 digit as the indicator for another dial-tone. It is used to make an off network call(get an outside line)..
R1(config)# ephone 1 R1(config-ephone)# mac-address xxxx.xxxx.xxxx R1(config-ephone)# type 7960 R1(config-ephone)# button 1:1 R1(config)# ephone 2 R1(config-ephone)# mac-address yyyy.yyyy.yyyy R1(config-ephone)# type 7940 R1(config-ephone)# button 1:2 Note: If you have more IP Phones, just add more ephone and ephone-dn block of commands. 3.5 Configuring the PSTN/POTS interface on the CME Router The PSTN/POTS cloud is being simulated by the ADTRAN Atlas550.
Note: The ADTRAN Atlas550 must be configured to forward calls to the PRI ports every time a 5555xxx number is dialed. Also, make sure you connected the CME Router’s PRI port to the right ADTRAN Atlas550 PRI port R1(config)# voice translation-rule 1 R1(cfg-translation-rule)# rule 1 /^555\(.+\)/ /\1/ R1(config)#voice translation-profile DID R1(cfg-translation-profile)# translate called 1 R2 doesn’t have PRI/T1 connection to the POTS/PSTN. There is no need to issue commands on R2.
The port command specifies which voice port will be used by the router to forward the calls to PSTN. Use the forward-digits command to specify how many digits, of the dialed number, will be forwarded, from left to the right. In this case, we are forwarding just the PSTN 7 digits, excluding the 9 used to gain the secondary dial tone. The port command specifies the voice-port used to forward/receive calls. In order to issue this command, you must choose the right voice-port to use.
Finally, connect a regular phone to the port 8 of the PSTN/POTS Module on ADTRAN Atlas550. The Atlas550 is configured to use the 555-600[1-8] numbers on the ports 1-8 of the PSTN/ POTS module. Connecting a regular phone to the port 8 of the PSTN/ POTS on Atlas550 makes this phone reachable by the number 555-6008. This regular phone is used to simulate a regular phone located at somewhere else in world. Step 5: Testing and Troubleshooting This scenario is simulating a real world situation.

Case Study 2: Registering IP Phones with a local CME and forwarding calls to a remote Call Manager Objectives • Place calls from IP Phones under R1 to IP Phones under R2 • Place calls from any IP Phone (under R1 and under R2) to the regular PSTN/POTS Phone • Place calls from the regular PSTN/POTS phone to IP Phones. Scenario The ACME Inc. has a new office in another city. In order to save money, a VoIP environment will be implemented by you.
R1 has IP Phones under it to and must be able to forward the calls from these IP Phones to R2’s IP Phones. R2 must be able to forward calls to POTS/PSTN and calls to R1’s IP Phones as well.
Switch1(vlan)# vlan 10 name DATA state active Switch1(vlan)# vlan 15 name VOICE state active Switch1(vlan)# exit i. Configure the switch ports where the IP Phones will be connected. Despite the fact that the IP Phones do work with access mode ports, Cisco recommends that you configure the switch ports, connected to the IP Phones, as trunk ports. This way, it is possible to connect a PC on the IP Phone’s PC Port (this port is present in most of the Cisco IP Phones).
Step 2 Basic CME Router Configuration o. In this lab, you will be working with two routers. Connect to their console port and power them on. If the routers have a configuration already on it, erase the router and reload it. p. Enter privilege exec mode. q. Configure the hostname, passwords, interfaces, console and telnet access, eigrp routing protocol like the figure and make sure that both routers can reach each other. Use the ping command to troubleshoot, if necessary.
The PCs and IP Phones will need IP Addresses. Configure the DHCP Pools on both R1 and R2 routers so the routers will be able to teach IP information to PCs and IP Phones. On R1: R1(config)# ip dhcp pool DATA R1(dhcp-config)# network 10.10.0.0 255.255.255.0 R1(dhcp-config)# default-router 10.10.0.1 R1(config)# ip dhcp pool VOICE R1(dhcp-config)# network 10.15.0.0 255.255.255.0 R1(dhcp-config)# default-router 10.15.0.1 R1(dhcp-config)# option 150 ip 10.15.0.
3.3 Configuring the Telephony Service on the CME Router On this scenario, R1 and R2 will be running the Cisco CME Software. The IP Phones connected at R1 will register on R1 and the IP Phones connected to R2 will register on R2. The first step it to enable the CME software on R1/R2. Use the telephony-service to enable the CME and enter the telephony configure mode. Note: You can use the telephony-service setup command to start a “configuration script” but it will not be used here.
You will need to setup the ephone-dn’s and ephones on R1 in order for the voice service to work. From the configuration mode, create the ephone-dn’s. The ephone-dn command is used to create the ephone-dn. number, description and name will be use to specify the phone number of this ephone-dn, set a description to this ephone-dn and a name, respectively.
R2(config-ephone-dn)# name George R2(config)# ephone-dn 2 dual-line R2(config-ephone-dn)# number 5022 R2(config-ephone-dn)# description MrSpacely's Phone R2(config-ephone-dn)# name MrSpacely R2(config)# ephone 1 R2(config-ephone)# mac-address uuuu.uuuu.uuuu R2(config-ephone)# type 7960 R2(config-ephone)# button 1:1 R2(config)# ephone 2 R2(config-ephone)# mac-address vvvv.vvvv.
R1 will receive calls from the POTS system, so it is necessary to make it handle these calls. In the real world the dial plan used is E.64 but here we have created our own dial plan and configured it on the Atlas550. The Atlas550 is configured to forward calls with 555-5xxx numbering destination to the PRI ports. Use the voice translation-rule, voice translation-profile, translate called and rule commands to setup a translation. In this scenario, the inside IP Phones and regular phones have 5xxx numbering.
need 2 dial-peers: one pots dial-peer type (will handle POTS/PSTN calls) and one voip dialpeer type (will handle the calls between R1 and R2). R1 must to be able to forward/receive calls to/from the POTS system and forward/receive calls to/from other IP Phones (registered at R1 and registered at R2) or internal regular phones as well (if using an FXS card on R1/R2, see IPTX Case Study Appendix-B).
Some small but important changes must be made on R2 commands. It is necessary to change the dial-peer type. On R1 the pots dial-peer type was used but since R2 has no direct connection to the PSTN/POTS, all calls from R2, heading phones outside from R2 have to pass through R1, only a voip dial-peer type will be necessary. Create 2 voip dial-peers type: one to handle calls to PSTN/POTS and another to handle calls to R1’s IP Phones.
the PSTN/ POTS module. Connecting a regular phone to the port 8 of the PSTN/ POTS on Atlas550 makes this phone reachable by the number 555-6008. This regular phone is used to simulate a regular phone located at somewhere else in world. Step 5: Testing and Troubleshooting R1 and R2 are CME capable routers. R1 is located at the main office and R2 is located at the remote office. The phones under R1 will register at R1 and the phones under R2 must register at R2.
Total Allocated ISDN CCBs = 0 Another useful command is the debug ephone register. This command allows you to track the e-phones register process. Disconnect on of the IP Phones. Issue the debug ephone register and then connect the IP Phone again. Take a look on the debug messages on the R1 console. The show running-config, show ip interface brief, show ip route, show ip protocols are very useful and powerful troubleshoot commands as well. Below are the basic configuration files for R1 and R2.
