Turning a Cisco 1841 into a CME router for Call Processing
Long story short and before the question pops up; My 1841 IOS version has the Telephony Service features available.
I am trying to make my 1841 router to act as CME to configure IP Phones. However, the IP Phones boots successfully and it gets their ephone-dn assigned to them from the TFTP Telephony Service configuration but when I dialed internally from one extension to another, I get a long silence (Dialing timeout) followed by a busy signal.
Before someone give me the resolution; do I need to configure Dial-Peers for internal calls for four digit extensions?
I was able to replicate the configuration in Packet Tracer without any dial-peers and the phones were able to call one another locally.
What am I missing on a real gear that is not meant for UC but the IOS allows you to configure it?
Let me also tell you how my topology is setup...
1841 --> HP 3400 Procurve ---> Cisco 3560 Layer-3
The 1841 is the default-gateway for VLAN 77, the TFTP for the IP Phones, and the Internet router for the all LANs
The 3400 is the interface vlans ip addresses each with the IP Helper-Address syntax configured
The 3560 is the DHCP server and PoE switch for the IP Phones
The IP Phones are booting to the correct vlan with the correct TFTP information. I can see the extension numbers on the screen but when I dial one another, it does not work.
Your best effort will be greatly appreciated.
Than you,

My configuration was correct. All my phones pulled the correct setting from my 1841 with the extension No. I assigned to them, but then I got the busy signal between extension and it is because I did not have any End-User license running in my 1841.
Thank you, and I accept you response. Very nice of you.
