SIP domains are domains authorized to send and receive SIP traffic, and are used when assigning SIP addresses to users. This cmdlet was introduced in Lync Server 2010.

What is SIP used for?

Session Initiation Protocol (SIP) is used to signal and control interactive communication sessions. The uses for such sessions include voice, video, chat and instant messaging, as well as interactive games and virtual reality.

SIP Features

SIP enables user mobility through a mechanism that allows requests to be proxied or redirected to the user’s current location. Users can register their current location with their home server. SIP supports end-to-end and hop-by-hop authentication, as well as end-to-end encryption using S/MIME.

What is the difference between VoIP and SIP?

VoIP, or Voice over Internet Protocol, is a family of technologies that enables voice to be sent over the Internet. SIP, or Session Initiation Protocol, is a protocol that can be used to set up and take down VoIP calls, and can also be used to send multimedia messages over the Internet using PCs and mobile devices.

Description

In order to configure SIP addresses for your users (and thus enable them to use SIP-related software such as Skype for Business), you need two pieces of information: a user ID (for example, Ken.Myer) and a SIP domain (for example, litwareinc.com). The SIP domain used to construct a SIP address must be a domain located within your Active Directory forest that is authorized to send and receive SIP traffic. For example, suppose you have domains named litwareinc.com, fabrikam.com, and contoso.com, but only litwareinc.com has been identified as being a SIP domain. In that case, you cannot use a SIP address like sip:Ken.Myer@fabrikam.com or sip:Ken.Myer@contoso.com, at least not until fabrikam.com and contoso.com have been configured as valid SIP domains. This is something you can do by running the New-CsSipDomain cmdlet.

The Get-CsSipDomain cmdlet provides a way for you to return information about the SIP domains authorized for use in your organization. The Get-CsSipDomain cmdlet also identifies the default SIP domain for your organization; this is the domain that Skype for Business Server 2015 will use, by default, if a SIP domain is not specified.

Examples

————————– Example 1 ————————–

PowerShellCopy

Get-CsSipDomain

In Example 1, the Get-CsSipDomain cmdlet is called without any parameters; this returns information about all the SIP domains configured for use in your organization.

————————– Example 2 ————————–

PowerShellCopy

Get-CsSipDomain -Identity fabrikam.com

The command shown in Example 2 returns information for any SIP domain that has the Identity fabrikam.com. Because SIP domain Identities must be unique, this command will never return more than a single item.

————————– Example 3 ————————–

PowerShellCopy

Get-CsSipDomain -Filter "f*"

Example 3 uses the Get-CsSipDomain cmdlet and the Filter parameter to return information about all the SIP domains that have an Identity that begins with the letter “f”. For example: fabrikam.com; fabrikam.org; fabrikam-users.com; and so on.

————————– Example 4 ————————–

PowerShellCopy

Get-CsSipDomain | Where-Object {$_.IsDefault -eq $True}

The command shown in Example 4 returns information about the default SIP domain. To do this, the Get-CsSipDomain cmdlet is first called without any parameters in order to return a collection of all the SIP domains configured for use in your organization. This collection is then piped to the Where-Object cmdlet, which selects the one domain where the IsDefault property is equal to True.

Parameters

-Filter

Enables you to use wildcards when specifying the Identities of the SIP domain (or domains) to be returned. For example the filter value “*.org” returns a collection of all the authorized SIP domains that have an Identity that ends with the string value “.org”.

Type:	String
Position:	Named
Default value:	None
Accept pipeline input:	False
Accept wildcard characters:	False
Applies to:	Lync Server 2010, Lync Server 2013, Skype for Business Server 2015, Skype for Business Server 2019

-Identity

Fully qualified domain name (FQDN) of the SIP domain to be returned (for example, fabrikam.com). If neither this parameter nor the Filter parameter is specified, then all the SIP domains authorized for use in your organization are returned.

Type:	XdsGlobalRelativeIdentity
Position:	2
Default value:	None
Accept pipeline input:	False
Accept wildcard characters:	False
Applies to:	Lync Server 2010, Lync Server 2013, Skype for Business Server 2015, Skype for Business Server 2019
