register 2 ext into 2 separate asterisk servers(Solved)

[mohsen_amin]

I have 2 Asterisk servers one for production and it is not exposed to internet ServerA "Has no RealIP"
the other ServerB "Has realip"
I want to register ext1 of my cisco 525G to server A and ext2 to server B
when i did this configuration only first ext can make and receive calls ext2 showing registered on serverB but not usable for incoming or outgoing calls

Does any one know how can i make this scenario work.

You are trying to register one hardphone in two differentes asterisk?
That is perfectly normal and should work.

What erros do you get and what do you mean by 'realip'? Public IP x Private IP?

Dear stuartalt

Thanks for your replay

actually in the web page of the phone showing both exten register , but i can only make and receive calls from ext1 when i am trying to make/receive call from ext2 i receive the following

Playback("SIP/500-00000126", "silence/1&cannot-complete-as-dialed&check-number-dial-again,noanswer") in new stack

Phone Ext showing registered on the phone WEB Page
Phone LED "Button" Only showing EXT1 information
Can make /receive calls only from/to EXT1
calls from EXt2 showing in EXt1 Server log with the following error
Playback("SIP/66666 -00000126", "silence/1&cannot-complete-as-dialed&check-number-dial-again,noanswer") in new stack

real ip is my real external IP address "Fixed Internet IP address".

[stuartalt]

Can you make the call again and provide de full call log?

Also,
If you are running two differente asterisk, you should have a trunk between then.
Make sure you have created the 'Outbound Routes' correctly.

Review that, as it seems that the dialplan doesn't know where to send the call.
