Hi,

I am trying to configure my Cisco 2811 with Call Manager Express 4.3 to allow generic SIP phone registeration (as well as the standard Cisco SCCP phones). I have used the following resources to create my configuration https://www.experts-exchange.com/Networking/Telecommunications/IP_Telephony/VoIP/Q_22615518.html?sfQueryTermInfo=1+call+express+manag+phone+sip and http://polydistortion.net/monkey/archives/2006/11/16/003924.html 
However the SIP phones sp not register. Once of the phones I am trying to register is a GXP2020 and allthough the phone doesnt register with Call Manager Express it is still able to place calls, however it cannot recieve any calls.

Below is my relevant configuration:

voice register global
 mode cme
 source-address 192.168.4.1 port 5060
 max-dn 12
 max-pool 12
!
voice register dn  1
 number 1234
 name My Phone
!
voice register pool  1
 id mac xxxx.xxxx.xxxx
 number 1 dn 1
 username user1 password mypassword
 codec g711ulaw
!

I would really appreciate your help with this one!

Thanks

Mark

Is the phone on the same network? does it get a DHCP address, config load, etc ....?

is there layer 2 and layer 3 connectivity? Is it pingable?

Yes its on the same network and it receives an IP from the routers DHCP pool and you can ping the phone from the router.
