Noob at SIP Trunking

[Scotty_IT]

Hi All,

More or less a noob when it comes to SIP trunking, and looking for some guidance

So here's the situation. Location A currently has 8 analog (POTS or roll over lines)coming into an IP Office 500 V2 (Version 10.1.0.4.0 build 7), 2 fax lines running straight to fax machines and one analog line
running to a boardroom for a conference phone. Pretty outdated.

What we want to do is ditch all the lines and switch everything to SIP, but keep all the same numbers.
We've found a local provider, (also providing a internet connection). If what I've learned so far, is that the provider will (Should) give us all the details to setup the new SIP line, but will it need to be a single sip line, or a line for each number?

Next question, we currently have incoming call routes setup for the existing numbers to route to our auto attendant, will any of this have to change if we keep the same numbers?

3rd Question, on the unit itself, we have each of the 8 lines plugged into the Phone8 card, do these need to be removed or reconfigured or new ones plugged in for the fax lines to work directly with the fax machines?

Is there anything else I've missed?

any help would be awesome!

Hello,
Normally your sip provider will give you the sip account and then assign numbers to it,
Your auto attendant should be unaffected you will just need to point the SIP DDI to it.
A phone8 card is for analogue extensions not lines, are you sure there isn't any ATM cards?

Depends on your provider. Some will serve all number with one single account. Others will need a single account for each number. Be aware to have enough channels available.

Best would be to get the SIP trunk with numbers to test (inbound, outbound, AA, call forwarding, twinning, sent number, ...) before you migrate the current numbers. If all works well it is mostly save to adjust the settings to match the correct numbers. If all is migrated, you should unplug the analogue lines.

Need some help with IP Office?

Side question: You guys finding faxing over internet facing SIP trunks works OK these days?

@kyle555, as long as they support T.38 we have no issues with it.

We have been hit and miss with fax over SIP, so have taken the decision (mainly because people should stop using faxes) to just not offer them as connected to any of our phone systems, especially now with Poweredby and Containerised making any analogue devices much harder to use anyway.

@CMUK, the system does have a phone2/ATM4 V2 card and a VCM32 V2/ATM4 V2 card. The ATM Card would be the converter as long as T.38 is enabled correct? so the Phone 8 card will be useless after the switch?
what will I need to do for the fax lines & conference phone to work from the system.
