Configuring office peers

If you have offices equipped with VoIP network, you can set up office peer trunks so that offices can call each other as if they are local extensions.

You can set up three types of peer offices:

Site to site: The office peer uses a FortiVoice unit and is in an equal position with your FortiVoice unit, rather than a primary/secondary relationship.
Remote access: The office peer uses a FortiVoice unit and is in a primary/secondary relationship with your FortiVoice unit.
Custom: The office peer uses a third party PBX.

For the office peers to call each other, make sure that your FortiVoice unit and the peer office PBX are mutually registered with each other’s IP address and SIP port number.

To view the list of office peer trunks, go to Trunk > Office Peer > Office Peer.

GUI field	Description
Fetch Office Directory	Select a trunk and click this button to obtain the phone directory from this office peer. This option only works if the PBX of the remote office is a FortiVoice unit and Fetch directory (see Directory) is selected on the remote unit. You can view the directory by going to Monitor > Directory and selecting this office in the Locations field. For more information, see Viewing call directory.
Enabled	Select to activate this trunk.
Name	The name of the office peer.
Display name	Enter the name displaying on the extension.
Type	The type of the trunk.
Server	The domain name or IP address of the remote office’s PBX. For example, `172.20.120.11 or peer.example.com`.
Port	The port number for VoIP network on the remote office’s PBX.
SIP Setting	The SIP profile applied to this trunk.
Status	The status of the SIP trunk. Not registered: The trunk is not registered with the VoIP service provider and is not in service. In service: The trunk is registered with the VoIP service provider and is in service. Unavailable: The trunk is not reachable. Alarm detected: There is a problem with the phone line. Admin down: The trunk is disabled. Unmonitored: The trunk is unknown.

To set up a remote access office peer

Go to Trunk > Office Peer > Office Peer.
Click New.
Under Office peer type, click Remote Access.
Select the role for the office peer: Master or Slave.

In a remote access office peer configuration, the salve peer registers to the master.

If you want to change your local number pattern, click the Edit icon beside Local/incoming digit pattern to modify it.
Review the basic New office peer information, click Next.
Configure the following:

GUI field			Description
	Name		Enter a name for the trunk.
	Display name		Enter the name displaying on the extension.
	Enable		Select to activate the trunk.
Peer Configuration
	Master Host/IP		This option is only available if you choose slave as the role of the office peer. Enter the domain name or IP address of the primary FortiVoice unit which is your office peer.
	Port		This option is only available if you choose slave as the role of the office peer. Enter the port number for VoIP network on the primary FortiVoice unit.
	User name		To authenticate the FortiVoice units forming the office peer trunk., enter the User name . This name must be the same on both units. The FortiVoice unit on each end will use this user name to authenticate each other.
	Password		To authenticate the FortiVoice units forming the office peer trunk., enter the Password. This password must be the same on both units. The FortiVoice unit on each end will use this password to authenticate each other.
	Outgoing digit pattern		Click the Edit icon if you want to modify the digit pattern of the outgoing dial plan for the local and peer offices.
	Advanced
		Local/incoming digit pattern	Click the Edit icon if you want to modify digit pattern of the local/incoming dial plan for the local and peer offices.
		Call routing	Select the call routing plan as required.
		Directory	Select this option and click Fetch now to obtain the phone directory from this office peer. This option only works if the same option is selected on the office peer's FortiVoice unit. You can view the directory by going to Monitor > Directory and selecting this office in the Office field. For more information, see Viewing call directory.
		Share metric	Enter the hop count value for this FortiVoice unit to share phone directory with a peer office. For example, if you enter 1, the directory can only be shared with the first peer office site designated on the routing table of this FortiVoice unit.
		SIP settings	Select the SIP profile for the trunk. You can edit the existing profile or click New to add a new one. For more information, see Configuring SIP profiles.
		Max channel	Enter the maximum voice channels for the trunk. This field accepts value in the range of 1-450 inclusive.
	More		This option is only available if you choose slave as the role of the office peer. This feature is used for remote access office peer connection through a proxy server, such as the case in a FortiVoice Cloud deployment.
		DNS SRV record	The DNS service (SRV) record provides host and port information for specific services such as voice over IP (VoIP). SIP needs to connect to a specific port on a specific server. Enable this option to allow the FortiVoice unit to query the DNS SRV record for the IP address and port number of the master FortiVoice unit (office peer) to register.
		Proxy	To connect to the master office peer through a proxy server, do the following: If you have enabled DNS SRV record, enable Proxy and enter the unique hostname of the master office peer in the (Host/IP) field. The DNS SRV record will use the information to look for and provide the IP address and port number of the master office peer. If you do not want to use the DNS SRV record service and therefore did not enable it, enable Proxy and enter the unique hostname of the master office peer in the (Host/IP) field. Also select the port number and communication protocol for the master office peer. The DNS server will use the information to look for and provide the IP address of the master office peer. If you know the IP address of the master office peer, enter it in the (Host/IP) field. In this case, you do not need to enable DNS SRV record.
		Registration interval	Select the time (in seconds) needed for your FortiVoice unit to register to the master office peer until it receives a response.
