In a previous tutorial, i demonstrated how we can register Third party SIP Softphone with Cisco Unified Communication Manager 5.x/6.x . In this tutorial, i will use another Softphone ‘ SJphone ‘.For multiple line capability(upto 6 lines/phone), use ExpressTalk .Basically, there can be two ways in which SIP phones can be used with a VOIP router.
1) Direct Mode
Here, we will use VOIP dial-peers to point to actual SIP phone.The Phone will not register to CME Router itself.This is similar to FXS port configuration on routers.This tutorial covers Direct Mode.
2) Register Mode
In second mode, SIP device will actually register to VOIP router/SIP proxy server in order to make and receive calls.Here, we will configure Username/Password configuration in sip-ua configuration in order for SIP phones to register .I will cover this in a follow-up tutorial.
Download Express Talk
Download SJphone
Enjoy !

@Efren,if you use IOS Software Version 12.4(9),you should be good to go.For digging deep into features and commands supported, i would highly recommend you to use Cisco’s IOS Feature Navigator online tool for help.

Hi,
I can telnet from Loopback adaptor into my GNS router and can ping to my Loopback adaptor from GNS router. Connectivity is absolutely fine.
I am using a SIP SJPhone Build 1.65.377a
When I try to simulate a VoIP call from GNS Router, I get these errors.
——————————————————————————————————
TelnetLab#csim start 2222
csim: called number = 2222, loop count = 1 ping count = 0
csim err csimDisconnected recvd DISC cid(2)
csim: loop = 1, failed = 1
csim: call attempted = 1, setup failed = 1, tone failed = 0
TelnetLab#
——————————————————————————————————
TelnetLab#csim start 6.6.6.5
csim: called number = 6.6.6.5, loop count = 1 ping count = 0
csim err:csim_do_test Error peer not found
TelnetLab#
——————————————————————————————————
TelnetLab#csim start 2222
csim: called number = 2222, loop count = 1 ping count = 0
csim err csimTimeOut t.o while disconnecting cid(2)
csim: loop = 1, failed = 1
csim: call attempted = 1, setup failed = 1, tone failed = 0

Hi, thank u for your tutorial. It was very helpful. I am able to successfully use X-Lite to register with CME. However, I am unable to make a call from a 7960 series Cisco Phone to the X-Lite client and vice-versa. Do you know what is missing?
My configuration is something like that:
ephone-dn 1 dual-line
number 1001
…
ephone 1
button 1:1
…
voice register dn 1
number 2001
…
voice register pool 1
number 1 dn 1
…
Thank you.
