Great video as usual Willie. I have a old landline number that I ported over to Google Voice exactly how you described over 4 years ago. Have considered the Obi200 for a few years now, but really don't use the Google Voice number anymore, it's just there, lol. However, I didn't realize it could be used with PBX systems. I may have to pick one up and attempt to marry it with FreePBX. Thanks.

I've had the Obi200 for years and love it. But I use mine with Callcentric and for $1.95/mo I get caller ID with name, Google Voice voicemail and 911 service. I like having a phone with 911 hanging on the wall in the kitchen. DETAILS: I ported my home phone number to Google Voice. When someone dials that number, GV forwards to my Callcentric number. Callcentric rings the Obi. No voicemail on the Callcentric, so after some rings GV picks up and takes the voicemail and emails the transcription. Outbound calls come from my Callcentric number, but I had them change the outbound caller-ID so that they appear to be coming from my home phone number. It all works great!

My older Obi110's also have a POTS line on them, so you can bridge between the VoIP or Obihai number and the POTS line. So for example I have one here in Canada and one at my parents house in New Zealand. So if I call their Obi from my Obi I can take control of it and then call out via their POTS line - essentially I can make a local to them call from here. Obviously there is a trust setup between the 2 devices. However with long distance pricing being so low these days it's not something I use much now.

Very nice informative video.

You mentioned jitter issues occurring at 150ms network latency. Do you have advice on how to reduce network latency for people in remote (rural) locations? I'm looking forward to learning more about the Grandstream UCM6202.

Great Video's! I have learned so much from them. I'm revisiting this video; but have a question of understanding. With the OHi200 or OBi202; once i set it up and have a google voice number/s with it. i can then plug the analog line out of the OBi into a Grandstream UCM6202/04 FXO port and get a "CO" line into the 6202/04? Many thanks in advance.

Hi Willie, Thank you so much for great video. It is awesome!!! Do you have video on how to use obihai google voice as a inbound and outbound trunk for Grandstream?? Thank you

Can you make a video about openvpn on the Grandstream phone, tried to set it up on PIA, but was unable to make it work.

Did you (or were you able to) connect your Cisco IP Phone to the UCM6204? If so which model Cisco IP Phone do you have and how?

Nice tool, thank willie, willie please recommend me some book to learn freepbx

If this is setup on the US on GV, can it then be used on a VPN in another country for calls in and out of the US?

Hey Willie, Can I set this up as an extension on a UCM where when the google voice number is called it's routed to the UCM and the IVR picks up and the prompts are played??

Jitter can happen regardless of lag/ms delay. When ur packets hit Wan there is no gaurentee packet 1 2 and 3 take the same route. Therefore there is no gaurentee they arrive in that order at the other end. Jitter is by definition out of order reception of packets. In a game it looks like an opponent jumping around instead of moving fluidly. In an audio codec it's just garbage, or if the codec can identify order its delay while sound is reassembled

Google Voice is not available in Canada any alternatives?

Can that system work in Jamaica?

is there more to porting a current land line fax number to the obihai fax than 1) get a cell phone and port the fax number to it. 2) establish google voice and port cell phone over to the google voice 3) disconnect cell phone. Is cell phone only a middle point and not needed once ported over? Rarely use fax but must maintain the service and number.

Can you use any kind of house phone into it ?

Are you getting the voicemails left on the google voice coming to your landline? I heard this OBI box will not port the voice mails to the landline number. Is that true?

Did you ever do a follow up video to this one where you provide more information about configuring Google Voice with an Obi200 and a Grandstream UCM (as you mentioned at 18:45)? I am trying to do that myself currently, but I am not having much luck finding information on the procedure. I have an Obi200, a UCM6301 and a couple of GXV3240 phones. My goal is to have an internal VOIP phone system using the Grandstream equipment with external calls going out/in via the Obi200. I know that using the Obi200 as a SIP trunk is no longer supported as it used to be on GV. However, is that somehow an option using some additional Obi/GV/UCM configuration in addition to what you cover in this video? Or possibly by using the the FXO port on the UCM to use the Obi200 as an analog trunk? I am very new to VOIP, so I'd apprecaite any advice you might have to point me in the right direction.

how to setup grandstream ucm6204 to polycom obi200

Would you please make the video you mentioned you would, involving setting up the Google Voice account, and using it with your OBiHAI? The OBi instructions on how to do this are from 2007, very dated. They ask you to use Google Chat, which has been terminated by Google, replaced by Hangouts. OBiHAI Tech support is effectively worthless, short email answers that don't resolve problems, then no answering of emails at all. OBi seems to rely heavily on their Forum for assistance, which is like the helpless helping the helpless. A person such as you Willie, could probably get this to work with Google Voice, but that is because of your VOIP knowledge, it wouldn't be from OBIHAI publications, especially as it relates to Google Chat not appearing in Google Voice as it used to be in 2007 when the instructions were originally created. My phone, for example, has a dial tone, allowing outgoing calls. But, I can not receive any incoming calls. When I pick up my phone, it stops ringing, but it is not connecting, and the phone calling in continues to here my answered phone ringing, as if it were not picked up. Very frustrating.

Willie, I heard Obihai and Google will drop their connection on Dec.31.2023 and that's the end of Obihai users? Hardware already discontinued?

Is there a system for the UK?

Stting is easy. I used Obihai202 with Google Voice. I have no problem getting google voice to work on my cordless phone. But the cordless phone cannot store google voice messages. Anyone know how to do it?

Willie Howe I am running a home office business and would like to setup an ip phone. Currently I have a copper line from my cable modem, in addition I am familiar and have a google voice number. Is there anyway to use my existing copper phone line for the backend calls. I know setting up an ip phone would require a pbx, I just need some solutions on getting to the outside lines.

I have comcast business with 5 analog phone lines coming from a comcast phone modem which comes off of comcast cable. And I would like to know how can I convert all of the phone numbers through comcast to sip to work with the Grandstream rack-mount server. Since the Grandstream only supports 2 FXS ports. How can I do such a thing?

OK, now I am confused as hell, just WHAT 'number' is this device using? is it an extension ONLY on your internal network OR is it the 510 number !! using direct dial ?

I really wish there was PBX software that was compatible with Google Voice. It seems only hardware devices support it.

help i just got this hooked it up and used google voice and it works no problem for regular home phone.... however i want to use it to send and receive faxes from my all in one hp printer copier scanner fax... it sends out no problem but does not recieve it will ring and answer but once it pick up it just says connecting then says"no fax to receive" any help would be appricated

Just a word of warning, Obihai was bought out a few months ago by Polycom. And now Polycom has been bought by Plantronics. So nobody knows what the future product plans are. I do own and use a Obi200 for VOIP only as GV is not available where I live. And now Obihai have stopped selling their products here too. So the future of Obihai isn't certain for me at least. The Obi200 has been released for 6 years now so you wonder how much more life it has. The upside is that it is still having releases for bugs in the software.

Now Willie you need to get to work on your cable management

I had GV working for several years, but Google removed XMPP around June 2018 which made my FreePBX fail. However, I understand that it will still work with the ObiHai using analog. What I don't know is whether the ObiHai can be used as a bridge. Any thoughts?

Why are you all of a sudden trying to push Grandstream products?? Grandstream is complete trash, especially in the VoIP market. I have never met a customer that has been happy with a Grandstream VoIP solution. Aside from their hardware being junk they have, without question, the worst customer support in the tech industry.
