It is a common request for end users that have stand alone/on-prem video conferencing units utilizing SIP/H.323 to call into Lifesize Cloud users and meetings. This is compatible with any system that utilizes H.323 and SIP, including the most popular brands like Polycomm and Cisco. 


To call to a Lifesize Cloud paired endpoint (220 series/Icon series endpoints), Cloud User using the Desktop, Mobile or WebApp or Virtual Meeting Room (VMR) follow the instructions below: 



Determining Best Call Node:


You will need to determine if your end user is utilizing SIP or H323, as we have designated FQDN for both SIP and H323 call bridges. These will be:






If using Windows 10:

1) Determine if you or your end user is utilizing SIP/H323

2) Type "cmd" in the Start Search Bar and hit Enter

3) Type "ping" -OR- "ping"

4) You will see that the ping will time out but we want to see the IP address listed in the brackets. This will be the IP that you can utilize for SIP or H.323 dialing.


In the below example, I am pinging and am getting




Dialing to Lifesize Cloud Users:


Now we have determined which IP is best for our end user, we can now have them dial our to the node from their stand alone endpoint system. 


Have them dial out to the selected Lifesize Cloud Node with an H.323 dial string and they should get to the Lifesize Cloud Bridge/IVR: 



Once getting to the IVR, they may enter in the extension of the Cloud Paired endpoint, user or VMR and should be connected to the meeting shortly afterwards. 


If there are issues with connections to the IVR from a stand alone system and you are calling to the closest Front End Node, feel free to submit a support ticket at Contact the Lifesize Customer Support Team or call us at our main support line at +877-543-3749.
