*Still have an issue, pls help! -- Dial remote site extension from external call

Unanswered Question


I have a question for you guys.

We have two offices connected to each other with two UC520

Office A


Extentions : 2XX

Office B


Extensions : 4XX

Now, internally, we can dial 4XX entensions from Office A and vice-versa

Is it possible for someone calling outside Office A to dial an Office B extension when asked to do so in the Auto-attendant?

Right now if I'm calling the Office A, auto-attendant is configured to ask the caller to enter the extension of the person the caller wants to reach. But this only works with 2XX extensions and not 4XX...

I hope I'm clear enough,

Thanks for your help!

I have this problem too.

To be able to dial from the AA, yo have to have a username with a phone number that CUE knows. Currently, this is only possible through the CUE GUI or CUE CLI. Notice these users DON'T have to have a mailbox.

Enter configuration commands, one per line.  End with CNTL/Z.

UC500-CUE(config)# username remote303 create

UC500-CUE(config)# username remote303 phonenumber 303

Well seems like it is working now thank you!

Only small issue though. If the contacted extension doesn't answer the caller gets a busy tone after 3 rings... Is this normal? Can this be changed so that caller falls in voicemail instead?

Caller -> Office A (AutoAttendant) -> Office B Remote Extension -> voicemail


Hello David,

Here are the debug files for both Office A and Office B.

What I did was call Office A from a cell phone (number 555-123-1234).

At the AA, I entered extension 323, AA told me it was composing that number.

323 extension is redirected to 399 (voicemail).

As soon as I get to 323, I get the busy tone, but if I remove the redirection to 399 and the user on 323 answers, it works...

If you need more info, don't hesitate to ask me!

Thanks a lot,

Hi Mathieu,

Do you also have the Dial-Peers in place to allow external calls to call the secondary site?
