IP Office 8.1. Working with PRI and pots.
Want to replace with SIP. What do I need to do?
Thanks

VCM resources and SIP licenses - one per simultaneous call. Also need solid network connection, and maybe a tweak on the firewall - depending on current configuration. Of course, you need a carrier to provide the service and maybe port the numbers. Is there something driving this? PRI usually works pretty good. To minimize your cost, you may be able to get SIP provider to give you a PRI handoff via a gateway, keeping your equipment/license cost at $0

Thanks Mike
SIP is a buzz word and cost savings is the reason, of course they are way over paying for a pri.

Is it worth the risk? If they do a ton of long distance calling and don't mind bad call quality every so often then it might be. If they don't do a lot of LD and expect their phones to sound crystal clear on every call, then I would recommend against it.

If they get SIP, they might have to invest in new network equip and a good IT guy to prioritize the voice traffic.

If they are not under contract, they can switch carriers for their PRI and probably save good money compared to what they're paying now with a new PRI. Here in LA, we're seeing a full PRI for as low as $300 sometimes. Depends on their location.
