Deploying a Conferencing Node in Azure
After deploying the Management Node and completing the initial platform configuration you can deploy one or more Conferencing Nodes in Azure to provide conferencing capacity.
To deploy a Conferencing Node in Azure:
Create a VM instance using the prepared Conferencing Node disk image. For more information on this, see:
- Obtaining and preparing disk images for Azure deployments
- Creating VM instances in Azure for your Pexip nodes
We recommend that each Conferencing Node VM instance is deployed in its own resource group.
After the instance has booted, perform a configuration-only deployment on the Management Node to inform it of the new Conferencing Node:
- Log in to the Pexip Infinity Administrator interface on the Management Node.
- Go to .
- Select .
- For deployment type, choose Generic (configuration-only) and select .
Enter the details of the new Conferencing Node, including:
Enter the Private IP address that you assigned to the VM instance (the ipAddress ARM template parameter).
Ensure that the mask matches the one defined for the subnet selected for the instance (the networkSubnetName ARM template parameter). For example a subnet with a /20 prefix size has a network mask of 255.255.240.0.
Gateway IP address
The gateway address is the first usable address in the subnet selected for the instance (e.g. 172.31.0.1 for a 172.31.0.0/20 subnet).
IPv4 static NAT address
Configure the Conferencing Node's static NAT address, if you have a assigned a public/external IP address to the instance.
Enter the public address allocated by Azure.
You must also specify other fields such as the Name, Role, Hostname, Domain, System location and assign a TLS certificate.
These fields are listed below.Full list of configuration fields (click to expand/contract) Option Description Name Enter the name that will be used to refer to this Conferencing Node in the Pexip Infinity Administrator interface. Description An optional field where you can provide more information about the Conferencing Node. Role
This determines the Conferencing Node's role:
- Proxying Edge Node: a Proxying Edge Node handles all media and signaling connections with an endpoint or external device, but does not host any conferences — instead it forwards the media on to a Transcoding Conferencing Node for processing.
- Transcoding Conferencing Node: a Transcoding Conferencing Node handles all the media processing, protocol interworking, mixing and so on that is required in hosting Pexip Infinity calls and conferences. When combined with Proxying Edge Nodes, a transcoding node typically only processes the media forwarded on to it by those proxying nodes and has no direct connection with endpoints or external devices. However, a transcoding node can still receive and process the signaling and media directly from an endpoint or external device if required.
See Distributed Proxying Edge Nodes for more information. Hostname
Enter the hostname and domain to be assigned to this Conferencing Node. Each Conferencing Node and Management Node must have a unique hostname.
The Hostname and Domain together make up the Conferencing Node's DNS name or FQDN. We recommend that you assign valid DNS names to all your Conferencing Nodes. For more information, see Assigning hostnames and FQDNs.
IPv4 address Enter the IP address to be assigned to this Conferencing Node when it is created. Network mask Enter the IP network mask to be assigned to this Conferencing Node. Gateway IPv4 address Enter the IP address of the default gateway to be assigned to this Conferencing Node. Secondary interface IPv4 address The optional secondary interface IPv4 address for this Conferencing Node. If configured, this interface is used for signaling and media communications to clients, and the primary interface is used for communication with the Management Node and other Conferencing Nodes. For more information, see Conferencing Nodes with dual network interfaces (NICs). Secondary interface network mask The optional secondary interface network mask for this Conferencing Node. System location
Select the physical location of this Conferencing Node. A system location should not contain a mixture of proxying nodes and transcoding nodes.
If the system location does not already exist, you can create a new one here by clicking to the right of the field. This will open up a new window showing the For further information see About system locations.page.
SIP TLS FQDN A unique identity for this Conferencing Node, used in signaling SIP TLS Contact addresses. For more information, see SIP TLS FQDN. TLS certificate The TLS certificate to use on this node. This must be a certificate that contains the above SIP TLS FQDN. Each certificate is shown in the format <subject name> (<issuer>). IPv6 address The IPv6 address for this Conferencing Node. Each Conferencing Node must have a unique IPv6 address. Gateway IPv6 address
The IPv6 address of the default gateway.
If this is left blank, the Conferencing Node listens for IPv6 Router Advertisements to obtain a gateway address.
IPv4 static NAT address
The public IPv4 address used by this Conferencing Node when it is located behind a NAT device. Note that if you are using NAT, you must also configure your NAT device to route the Conferencing Node's IPv4 static NAT address to its IPv4 address.
For more information, see Configuring Pexip Infinity nodes to work behind a static NAT device.
Static routes From the list of Available Static routes, select the routes to assign to the node, and then use the right arrow to move the selected routes into the Chosen Static routes list. For more information, see Managing static routes. Enable distributed database
This should usually be enabled (checked) for all Conferencing Nodes that are expected to be "always on", and disabled (unchecked) for nodes that are expected to only be powered on some of the time (e.g. cloud bursting nodes that are likely to only be operational during peak times).
Determines whether this node can be accessed over SSH.
Use Global SSH setting: SSH access to this node is determined by the global Enable SSH setting ( ).
Off: this node cannot be accessed over SSH, regardless of the global Enable SSH setting.
On: this node can be accessed over SSH, regardless of the global Enable SSH setting.
Default: Use Global SSH setting.
Enter the password to be used when logging in to this Conferencing Node's Linux operating system over SSH. The username will always be admin.
Logging in to the operating system is required when changing passwords or for diagnostic purposes only, and should generally be done under the guidance of your Pexip authorized support representative. In particular, do not change any configuration using SSH — all changes should be made using the Pexip Infinity Administrator interface.
- Select .
Selectand save the XML configuration file.
A zip file with the name pexip-<hostname>.<domain>.xml will be downloaded.
You must now upload the XML configuration file to the new Conferencing Node:
Browse to https://<conferencing-node-ip-address>:8443/ and use the form provided to upload the XML configuration file to the Conferencing Node VM.
If you cannot access the Conferencing Node, check that you have allowed the appropriate source addresses in your
security group inbound rulesfor management traffic. In public deployments and where there is no virtual private network, you need to use the public address of the node.
- Select and select the XML configuration file.
- Select .
The Conferencing Node will apply the configuration and then reboot. When it has rebooted, it will connect to the Management Node.
You can close the browser window used to upload the file.
After deploying a new Conferencing Node, it takes approximately 5 minutes before the node is available for conference hosting and for its status to be updated on the Management Node. Until it is available, the Management Node will report the status of the Conferencing Node as having a last contacted and last updated date of "Never". "Connectivity lost between nodes" alarms relating to that node may appear temporarily.
