Hi,
I thought I'd revive this thread as I'm interested in the systems mentioned here, but as an end user with little telephony knowledge I'm still unsure about many things.
First, some context. I live in Chile but work for a US business and spend 1-3 hours per day on the phone. We're from Europe where we have friends and family. We're Currently using Vonage (which provides us with US and French phone numbers) and Skype on the discontinued Philips VOIP 841 system with 3 cordless handsets. We're also using a Chilean phone company but only for local calls. We bought a 4,000 sq ft house that we're in the process of renovating so we have the opportunity to redo things to serve our residential and home office needs. I've already planned to wire the whole house with cat6 Ethernet cable for data purposes.
Now, our main requirements for the phone system:
- Is future proof and will be able to work with an SIP provider.
- Handles local (Chilean) POTS line.
- Includes an intercom (we have four floors), handles door ring (with its own ring tone).
- Supports cordless phones.
- Caller ID, distinctive rings, last number redial.
- External call forwarding. If someone rings the door bell and we're away, I'd like to get it on my cell phone. For security reasons (relatively high burglary rate where I live) I don't want people to know when there's no one home.
- Internal call transfer between handsets.
- PC-based admin. I'm a PC guy and would love to administrate my phone system like I do with my routers and network attached storage.
- Less technically daunting and time-consuming than setting up a dedicated PC with Asterisk. I'd like something that "feels" more like an appliance, yet can be administered.
- Total hardware cost (system + 3 or 4 handsets and door box) hopefully below $1,200 (excluding cabling and setup, which I hope I can use the local guy I talked to for).
- I don't care too much about voicemail because Google Voice takes care of it for me (well at least for US calls, but those are the ones that matter).
- Conferencing nice to have, not a must have.
- Reliable and well-maintained. I don't want junk that doesn't see any firmware upgrade after it's shipped (Philips, I'm looking at you).
I've talked with a local installer but his default answer (through someone else before talking with me) was Nitsuko 308... not exactly cutting edge!
This thread tipped me about the NEC DSX-40 but I wanted to clarify a few things:
- It looks like VOIP support has been added recently with a firmware upgrade, but I'd need to buy an addon card as well, right? Will this let me use any SIP provider (I'm currently using Teliax on my Nokia smartphone), or am I confusing what the DTX-40 can do with a full-fledged PBX? I don't trust that Vonage will be around forever (besides they're proprietary and a bit expensive) while Skype and its hardware partners have dropped the ball on dual-use residential phones (I thought a hybrid DECT/VOIP phone was a genius idea but apparently Skype didn't - and again Skype is proprietary - don't want to be entirely dependent on either company in the long run).
- I'd like to confirm I understood the brochure [*] right about handsets. You can use (up to 8) IP phones and they can come from different brands right? What about regular analog phones, you can use up to two, correct?

https://www.necdsx.com/docs/files/brochures/1093062_rev2_11.pdf - If I buy DTX phones (or other IP phones for that matter), they will work with cat6 cable, right? Does it matter whether the cables are terminated with T568A or T568B termination? With RJ11 adapters for our analog phones, we wouldn't even have to wire the house with RJ11 cable, correct?
- What's the range of the DECT cordless units and at what range is it advised to start using repeaters?
I've looked at the Panasonic KX-TA824 and TAW848 too but they don't seem to support VOIP, do they? Earlier in the thread people also mentioned the Samsung iDCS/OfficeServ 100, it looks close to the DSX-40 in terms of feature, anything major to tell them apart? Did anyone look at Talkswitch?
Sorry if this message is overly long and betrays extreme phone noobishness, but I'm out of my element outside of the IT/internet world. Thanks for any help.
