[cisco-voip] Caller ID between 2 voip system

["François T. - Liste de distribution]

Hi,

We are using a call manager at my office and when we are trying to reach 
a remote call manager trough the PSTN, I can see the internal extension 
on my phone when the call is connected. We are both using PRI with dms-100.

1. I dial 5551212, phone displays (To 5551212)
2. The call gets answer by the remote system, phone displays (To [unity 
extension])
3. I enter the extension I want to reach (5555) , phone displays (To 5555)

This issue only happens when the calling party and the called party are 
using Call Manager.

Is there any way to prevent this?

Thanks.
