View source for SIP Trunk (Zenitel Connect Pro)

{{C}}
==Introduction==
Zenitel Connect Pro (ZCP) can be interconnected to a SIP Server (e.g. iPBX or Call Manager) via a SIP trunk. 

There are two ways to call from a user in ZCP out on the SIP trunk:
* '''Prefix''': Dial the Prefix + the external extension number
* '''Integrated number plan''': Simply dial the extension number without any prefix

{{note| SIP Trunking is a licensed feature. A [[Licensing_(Zenitel_Connect_Pro)|ZCL-PBX license]] is required per trunk}}
__TOC__

== Adding the SIP Trunk and defining the Prefix==
Go to '''Devices and Connections''' > '''External Communication''', select Trunk Type '''External iPBX communication''' and click the [[File:ZC_PlusIcon.PNG|25px]] to add a new trunk.

* '''Prefix''': The digit(s) to dial to access the trunk
* '''Name''': Any descriptive text
* '''Peer Address''': The IP address of the SIP Server. If the peer uses a port other than 5060 or 5061 it can be added to the address.
* '''Call Service''': [[Permissions and Call Services (Zenitel Connect Pro)|Call Service]] for an incoming call. 
* '''SIP Transport''': protocol to use (UDP, TCP or TLS)
* '''SIP Authentication''': Username and Password to authenticate towards the SIP server
* '''Medias codecs:''' Options are G722, G711u, G711a, GSM, H264, L16x48
* '''Media encryption''': Choose No or SRTP (secure RTP)
* '''Status''': Reachable or Unreachable. Tells if the connection is up or down.

== Integrated Number Plan ==
It is possible to define outgoing number ranges. Numbers in these ranges can be dialed directly, without the need to dial a prefix. This gives a possibility to make a integrated numbering plan for all SIP trunks in a linked network.

To define the outgoing numbers, select a defined trunk and click on [[File:ZC_NumberlistIcon.PNG|25px]] on the left.

In the '''Outgoing Numbers Range''' pane, click on [[File:ZC_PlusIcon.PNG|25px]] to define a new range and enter the '''From''' and '''To''' directory numbers.

{{note|
* ''It is possible to add multiple ranges for each SIP trunk connection.''
* ''A range consisting of a single number must have that same number entered both in the '''To''' and '''From''' column.''
* ''The '''To''' and '''From''' directory numbers must have the same number of digits.}}
