asterisk users - Sep 2005 - Creating an OPX from a traditional PBX using Asterisk and a SIP device

Is it possible to use Asterisk and a SIP device to create an off premise
extension (OPX) from a traditional PBX?  For example:  I want to be able to
have full internal PBX functions and features but be off site.  I know this
is easily done IF Asterisk is the PBX but in this case the customer already
has an existing PBX and I want to augment it using Asterisk.  In the past
you would have to order a dry copper loop to wherever it was that you wanted
the OPX.

 

Thanks for any help.

Without being completely unhelpful, this all depends on the existing  
PBX with which you are trying to integrate asterisk. If it has analog  
extensions, probably easy. If not, probably harder. If it has a T1  
interface that you could connect to Asterisk via a cross-over cable,  
possible, but it all depends.

Hard saying, not knowing what sort of system you are talking about.
