I'm doing some heavily discounted work for a local charity getting them off a $300/month Vodafone bill for their landlines and broadband.

They've got a Toshiba Strata CIX100 PABX with 3 analogue outside lines and a bunch of internal lines with fancy Toshiba business phones. I'd like to move them to 2Talk. I have no experience with PABXes other than running Asterisk as a hobby 10 years ago...

Is it worth trying to program their PABX (will it even talk through NAT?) to connect to 2Talk?

Would replacing the analogue lines with a multiline SIP gateway be a better idea (e.g. a Granstream HT704)? Would that work at all?

I was originally planning to just get them IP phones talking straight to 2Talk but the receptionist likes the lights on her phone that tell her if the offices are off-hook/etc.

How many phones are you running?

The BLF lights work fine on 2talk through the cloud pbx on something like GXP1630

Are you sure they are analogue lines coming in and not ISDN?

Are you sure the PBX even supports SIP? Even if it does it probably requires licencing.

The information I have on BLF not working must be out of date. Well, we can just buy a slightly better phone for the receptionist then. That's lower risk then me tinkering with the PABX.

Is there a way with 2Talk to let other extensions pick up the receptionist's line if it's ringing and not being answered? Edit: I guess that's what *88 does, I just need to program a button on the phone to do that.

Edit: The PABX says "IP" on it but I've read some documentation and looks like it would require a SIP line card which it may not have (certainly it's not in use) and yeah, probably a SIP license too.

They're on a Vodafone small business plan that comes with two lines and ADSL. No mention of ISDN on the bill. Plan is to get UFB in with Inspire Net, then port the phone numbers over to 2Talk.

I wouldn't even try to set up the existing PBX with SIP natively. As you mentioned, it probably needs either an IP card installed or some licensing. And there are very very few Toshiba's around - I don't even know who sells them.

Being a charity I wouldn't even think about going and buying a bunch of new SIP phones and just simply get a SIP gateway. Assuming they are just POTS lines anyway? So one of the Obihai or Yeastar (just my personal favourite lately) gateways would suffice. Means no re-training for the receptionist but they get all the cost savings.
