SIP client not registering on Cisco Call Manager Express

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/questions/22615518/Call-Manager-Express-Accept-Generic-SIP-Registrations-Clients.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

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.

I am currently having the exact same issue - my SIP phone can make calls, but cannot receive them.

Did you ever determine what the problem was?
