Telephony Advisor for Exchange Server 2007

Topic Last Modified: 2009-04-20

Unified Messaging (UM) requires that you integrate Microsoft Exchange Server 2007 with the existing telephony system for your organization. A successful deployment requires careful analysis of your existing telephony infrastructure and for you to perform the correct planning steps to deploy Unified Messaging. However, the planning phase can be a significant challenge to Exchange administrators who have little or no experience with a telephony network. To help address this challenge, see Resources to Help With Your UM Deployment later in this topic.

To see the supported IP gateways for Unified Messaging, if your PBX is supported using a specific IP gateway model or manufacturer, or if your IP PBX is supported using direct SIP connection, click one of the following links:

Telephony networks are quite diverse and proprietary because they can include IP gateways, IP PBXs, and PBXs that all have different configuration settings, firmware, and requirements. This diversity makes planning and deploying Unified Messaging somewhat challenging. However, several resources are available to assist you in successfully deploying Unified Messaging:

  • Unified Messaging specialists   UM Specialists are systems integrators who have received technical training about Exchange 2007 Unified Messaging that was conducted by the Microsoft Exchange engineering team. To help ensure a smooth transition to Exchange 2007 Unified Messaging from legacy voice mail systems, Microsoft recommends that all customers engage with a UM Specialist. For contact information, visit Microsoft Exchange Server 2007 Unified Messaging (UM) Specialists.
  • PBX configuration notes   PBX configuration notes contain configuration settings and other information that is very useful when you are configuring IP gateways, IP PBXs, and PBXs to communicate with the Unified Messaging servers that are on the network. For more information about PBX Configuration Notes, see PBX Configuration Notes Tested by Microsoft or IP Gateway Vendor Partners.

Before you engage a Unified Messaging specialist, you should be able to answer key questions that they will ask. Having the answers to the following questions will help make the conversation between you and the UM Specialist productive:

  • How many existing telephone or voice mail users, or both, are in your organization?
  • How many users do you intend to provide with Exchange 2007 Unified Messaging?
  • Which PBX or PBXs do you intend to use for integration with Exchange 2007 Unified Messaging?
  • How many PBXs does your organization have? Please specify the vendors, types (circuit- or IP-based), models, and firmware versions.
  • Are the PBXs networked, and are they centralized or located in multiple locations?
  • What voice mail system or systems does your organization currently use? Please specify the vendors, types, models, and firmware versions.
  • How are the voice mail systems integrated into your PBXs (Analog, T1/E1, PRI, Digital set emulation, VoIP, other)?
  • Are you currently using voice networking?
  • What type of fax system or systems does your organization use, and does the fax system or systems support inbound fax routing to Exchange?
  • Does your organization use automated attendants?
  • Do you require support for phone-only users, that is, users that will have no e-mail access?

Integrating Exchange 2007 Unified Messaging with PBXs requires that you use one or more IP gateways to translate the circuit-switched protocols that are used by TDM-based PBXs to IP-based, packet-switched protocols that are used by Exchange 2007 Unified Messaging. IP gateway vendors with several models of IP gateways have been tested and are supported for Exchange 2007 Unified Messaging.

Interoperability testing of Exchange 2007 Unified Messaging with IP gateways is now integrated with the Microsoft Unified Communications Open Interoperability Program. For more information, see Microsoft Unified Communications Open Interoperability Program.

The Microsoft Unified Communications Open Interoperability Program qualification program for IP gateways and IP PBXs ensures that customers have a seamless setup and support experience when they're using qualified telephony gateways and IP-PBXs with Microsoft Unified Communications software.

Only products that meet rigorous and extensive testing requirements and conform to the specifications and test plans receive qualification.

Interoperability was verified for the following IP gateway vendors in the following years:

  • AudioCodes and Dialogic: 2006
  • NET and Quintum: 2008

Each Dialogic IP gateway model supports different PBXs. Tables 3, 4, and 5 show you the PBX manufacturer and model and which Dialogic IP gateway can be used. Each IP gateway uses different signaling methods, densities, and protocols.

PBXs Supported Using a DMG1000 Series Media Gateway

Table 3 shows the PBXs that are supported with the low-density Dialogic Media Gateway (DMG1000). However, when an analog DMG1000 is used, supplemental signaling (RS232 SMDI, MD110, MCI protocols, or Inband DTMF signaling) is required.

PBXs Supported Using a DMG 2000 Series Media Gateway

Table 4 shows the PBXs that are supported with the T1/E1 Dialogic Media Gateway (DMG2000). The DMG2000 gateway, which comes in single span (DMG2030DTIQ), dual span (DMG2060DTIQ), or quad span (DMG2120DTIQ) densities, supports the following protocols:

  • T1 CAS
  • T1 Q.SIG
  • E1 Q.SIG
  • T1 NI-2
  • T1 5ESS
  • T1 DMS100

If Channel Associated Signaling (CAS) signaling is used, supplemental signaling (RS232 SMDI, MD110, MCI protocols, or Inband DTMF signaling) is required. If Q.SIG signaling is used, the PBX must support the supplemental services that are associated with calling and called party Information and the call transfer capabilities required by Exchange 2007 Unified Messaging.

1) There SIP Trunks are coming over the internet from south Africa and they want to use those SIP trunks through Mitel IP phones for incoming/outgoing calling.Is there any way to terminate those trunks in 3300 ICP or any alternate way to use those trunks.Please suggest.

2)Customer want to dail from Third party sip phone to Mitel phone.
Suppose if they want to make a call to 1008(Mitel Ext) then they have to dial Extn.No@IP Address of the PBX i.e 1008@10.42.6.2 from the SIP Phone.
If they want to make a call to 1008 from the Outside over internet, then they need to dial 1008@202.174.123.12 (Public IP address(202.174.123.12) which is routed to Mitel PBX local IP(10.42.6.2 ).
Is it possible to have this arrangement for calling?
