Hangouts Meet and Polycom Trio

GrahamWalsh

If you are using Hangouts Meet, you are used to the video in a browser. Now how do you integrate with say a Polycom Trio device that can also do video in a huddle space or conference room? Well you can do this Pexip certified interop for GHM.

Firstly you will need to have Pexip Infinity deployed – details here. And then carry out the Hangouts Meet <> Pexip integration here.

Finally, you will need to register your Polycom Trio to Pexip Infinity as an example. This is detailed here.

Creating a Hangouts Meet invite

Once this is all done, we can now go ahead a book a meeting in the Google Calendar.

However, there is no Third Party joining instructions here in the meeting invite. To get these, you need to open the meet URL to join the meeting.

Once you’ve joined a meeting, you will then see Meeting Details in the bottom left corner. Click on this and then click on More Joining Options

That will then open a new window and you will see the Audio conferencing dial in details if you have these. Then click on Third-party systems

When you are in Third-party systems tab, you will see a few items. First up, you will have a short conference ID. If you have a Trio registered to the same platform as the interop platform, then you can just dial say the 6 digit ID and join the meeting. Next is a sip: link, so that will invoke the default SIP client on your computer, which could be Skype for Business. Alternatively you can type this on your Trio screen to connect. Finally is the IP dialling if you want to give yourself some pain.

Getting the Hangouts Meet info to the Polycom Trio

To achieve this, simply copy and paste the all the information from the Third-party systems tab and paste it into a calendar invite. I have pasted this into the Outlook calendar invite. Remember the Trio can only register to Microsoft Exchange mailboxes.

Once configured, your Trio will look like this.

Now you could just tap the Hangouts Meeting icon and it will dial the IVR. You could then enter the 6 digit ID I have in my example above. However, as you can also send the Trio the calendar invite, you will get a Join button like below.

Once you hit the Join button, it will then read the meeting invite and find [email protected] and dial that into the meeting

Depending on your settings with Pexip and Hangouts, the device may join as Trusted or Guest. Further details on this can be seen here and here.

Google Calendar Only?

If you do not have Microsoft Exchange where you can register your Trio’s to, fear not. Synergy Sky Join is a third party application that can act as an Exchange EWS emulator (this can also be used for Polycom HDX systems). Full details on setting up Join with Google Calendar is detailed here.
