Will this phone work with externally hosted systems like 8x8.com? I have a phone that is out of warranty and needs replaced.

I don't know exactly how the 8x8.com service is configured, but it is a standard SIP phone that can be configured to register to any IP address (private or public). Assuming they are using a SIP based hosted PBX and you can get through the firewalls, then yes. If you are not skilled in configuring these phones and 8x8 does not offer specific configuration steps for this particular phone, I don't recommend it. You are probably better off getting something fully supported by your service provider...

Yes it should, depends on the provider though. You would need the SIP credentials, which you would put in through the phones web interface

These phones utilize the SIP protocol. If 8x8 uses SIP, then it should work.

I have no idea what this phone is but as long as it has expandable memory it should work. if this is an older model phone do not purchase more than a 4GB memory card. 8GB-64GB are considered High Capacity and older phones will not take them

Yes, it will work; however, many, many apps will not support it. I don't know how to fix it.

You'll need to contact your service provider it's unlocked so it should work on most GSM carriers and it should be able to handle a 64 GIG

My existing phones were the 84209, I expanded my phone system by adding the 80109's and they worked fine with the base unit. Yes they were compatible.

I use mine with Verizon. If you call your carrier and ask for tech support they should be able to tell you if they support it.

We have an avaya system, and run them through it. External dialing and extension dialing work fine, but special features like voicemail and programmed buttons may not.

Yes, mine worked with straight talk. All I can say is be careful, if you are in the USA there is no warranty on it because it was manufactured in the UK. They will not honor the warranty unless you have friends or family in England to whom you can send the phone if it needs repair. They will have to send it to the repair site. They don't tell you that. No warranty. Sad.

Yes, if it is manually configured in your network settings. But after a few months it wouldn't allow me to send or receive multimedia msgs and it could never be configured again and they said it just wasn't compatible. Also screen is very small, I ended up getting an HTC Amaze a bit later.

I'm pretty sure it can. I know you can configure it for both internal and external use, but just to make sure try contacting them directly.

This 800 is an international version, that means any service provider that uses a GSM network in any country (GSM providers, use a SIM) is compatible. That is what this type of phone is all about........:)

Could not use this phone with version towers in US. AT&T; was the only opion. Phone unlocked is not registered with version. Living in a rural community at&t; had no reception

These phones work with a Digital PBX (Asterisk, 3cx..) or VOIP service provider (Callcentric I have used myself)

Only if your local phone company supplies it. The phone will work with the system.

Not at all. But keep in mind that this is a satellite phone, it needs a master server phone for this phone to operate. I bought these phones myself, had 2 left over so I sold them here on Amazon, practically overnight. I don't know why people dislike this phone, I too read some reviews about this phone.

You must contact the seller and tell them that you need a specific version because there are several versions of this smartphone. I bought one for one carrier and the one I received did not work for it so I had to use it with another carrier against my will.

The phone came with no branded software /bloatware. It will work with any carrier on 800,1900,or 2100.
