Regarding your phone registration issue in CME, try to factory reset the phone while it is connected to CME. Unplug the ethernet and as soon as you plug it back in, press and hold # sign until the line buttons start flashing. After that press all the buttons in the keypad from 1 to #. It should reset the phone to factory default and download new firmware from CME. HTH.

Hello ,can i get any ideas??????

Hi

Please run a "debug isdn q931" on the GW and make the call. Check if the CLID is OK when the call leaves the gateway (maybe the pbx is changing the clid)

If not, check the external phone number mask on DN/RL/GW

Mohamed,

1) First of all, delete all CTL or Trust list files from the phone. Then do factory reset.

2) As another vendor is involved, we have so many factors to be considered. First of all, we need to isolate the trouble. The ideal and logical way is to enable debug in MGCP gateway and verify what digit is being sent from MGCP gateway -----------> Ericson PBX.

If you see 1111 there, then lets look in CUCM side. If not, then we will check Ericson PBX.

Also, for the phone issue, load the GUI of the 7975 using web browser and check what logs/ status messages do you see there. Thus we can understand what exactly is the status of the phone.

Hi Mohamed.

Maybe the following document could explain your forwarding issue.

http://www.cisco.com/en/US/solutions/collateral/ns340/ns414/ns728/ns784/703946.pdf (page 3)

"On a call that originates from an Ericsson MD110 PBX extension to a Cisco Unified IP Phone (registered on CUCM 7.0) that is

forwarded unconditionally or on busy back to a PBX extension on the same PBX, and where reroute is invoked, the forwarding name is

not displayed on the final destination. This is a new limitation of the PBX and was not seen on the previous release (BC12, SP5)."

Regards

Carlo
