Introduction
my company has a 40+ phone system with both DECT and wired phones. the wired phones, coming from different periods have either UTP wiring or classic 4wire phone cabling. NO SIP/VoIP is in place
PBX is an Aastra 470.
voice comes from fiber router, enters a IP to ISDN converter and 4 UTP wires plug 8 lines into the PBX.
so far so good.
Now we are introducing a new ERP in the company, the ERP has an asterisk based VoIP solution to notify incoming calls into users pc, providing augmented info about the incoming call.
The problem
I'm wondering if is possible to introduce the asterisk based solution along with our current PBX (and setup in general). Infact, the asterisk solution will serve the customer care office with around 10 phones, while it will be of no interest for the other offices/building.
We do not want to rebuild the entire infrastructure for this, but the solution seems attractive for the customer care office. Of course we will update phones to VoIP solutions here.
question
is there a way to connect the 2 PBX, more generally, is it possible to use an asterisk based solution to manage a group of SIP phones and then , let say, daisy chain the current PBX, leaving everything else untouched?
the idea is to add this on top of the current infrastructure, avoiding big changes.
As no one here has expertise in this I'm asking for links/pointer or direct answers to clarify what could be done.
thank you.
