SIP/ANALOGUE VOIP ON SV8100 AND SL1000

[Brollox]

I'm starting a new NEC Dealership and need your guys opinion, I want to sell Voip and want to know what do you guys think is best; SIP or Analogue Voip. I'm from a Samsung environment and is used to the SIP trunk way, because when a call fails on SIP it automatically fails over to your (backup) overflow trunks which analogue does not do, what I need to know is SIP on the SV8100 and the SL1000 stable and does it also automatically overflow when SIP is failing?

Sip trunks work well on the SV-8100. Check NEC's web site for the latest suggested and tested SIP providers and the NTAC site for installation documents. Failover is up to you and your LCR/ARS programming.
