- How many SIP Trunks (call paths) are we providing? (up to 23 per PRI, SIP is not restricted)
- What is the signaling with the PBX? (SIP/PRI)
- If PRI, What is the switch type? (4ESS/NI2, NI2 is Default – T1 defaults will be ESF/B8ZS)
- If PRI, will the PBX or the PRI be the clocking source? ( PRI is default)
- If PRI, Evolve IP will be the DCE.
- If SIP, what will the PBX send as its user agent ( device type)?
- If SIP, does the equipment support the REGISTER method?
- Will the PBX be redirecting calls outbound via the trunk?
- If yes, what IP will traffic come from?
- What is the physical location (city, State) of the PBX?
- Do we need to setup Call Forward Not Reachable? This means that Evolve IP will automatically route calls to another number in the event of PRI failure.
