In this deployment, following LYNC topology entities, PBX, and numbering plans are used:

Before You Begin

The SBC SBA must already be configured. If not, configure and deploy the Lync SBA following the instructions in Preparing for SBA Deployment - First Steps.

Lync Configuration

Creating analog End Point using the New-CsAnalogDevice Command

Analog Endpoints must be created from the Lync Management Shell using the New-CsAnalogDevice cmdlet.

1. On the Lync Server, go to Start > Microsoft Lync Server 2010 > Lync Server Management Shell.
   Enter the command as shown below.

For Aanalog Phone Endpoints:

New-CsAnalogDevice \-LineUri tel:+15102462001 \-DisplayName "Analogph1" \-RegistrarPool cspool.uxdemo.net \-AnalogFax $false \-Gateway ux246.uxdemo.net \-OU "ou=Analog,dc=uxdemo,dc=net"

For Analog FAX Endpoints:

New-CsAnalogDevice \-LineUri tel:+15102462003 \-DisplayName "Fax1" \-RegistrarPool cspool.uxdemo.net \-AnalogFax $true \-Gateway ux246.uxdemo.net \-OU "ou=Analog,dc=uxdemo,dc=net"

Before running the commands above, make sure that the relevant Organizational Unit(OU) (in this example it is named Analog) exists in Active Directory. On a machine that can access the Active Directory Users and Computers snap-in, launch the Active Directory Users and Computers snap-in and verify that OU is present as shown in below screenshot:

• Launch the Lync Management Shell and run the relevant commands to create both Analog Phone and Analog Fax Endpoints as shown in below screenshot:

• Verify in Active Directory Users and Computers snap-in that relevant users are created successfully in Analog Organizational Unit as shown below:

Explanation of New-CsAnalogDevice

The New-CsAnalogDevice cmdlet instructs Lync to route calls from the analog device to the gateway specified in the -Gateway switch of the cmdlet; thus, ensuring that Fax calls will safely be transmitted over PSTN.

Creating a Route For Calls From Tenor to Lync

• In Configuration Manager, right click on Number Tables in left pane and select New as shown below

• Create a new Number Tables to allow Analog Endpoints to be able to make calls to LYNC endpoints as wells as to PBX endpoints as shown below

• Create an entry in the Routing Table as shown below

• Modify the default Number Table to allow incoming calls to Tenor Device as shown below

• Verify that "Use Routing Table" option is selected in Gateway configuration field as shown below

Verifying Codec Selection

• Verify that Voice Codec settings are configured correctly as shown below

Verify Supplementary Services Enabled

Tenor supports the following supplementary services - Hold/Unhold, Unattended (Blind) Transfer, and Attended (Consultative) Transfer. These features can be enabled and configured using either a Line Circuit Routing Group (LCRG) or Trunk Circuit Routing Group (TCRG). Follow the configuration steps below:

• Verify that "Detect Flash Hook Signal" option is selected in CAS Signaling Group-phone > Signaling Tab

• Verify that "Generate Flash Hook Signal" option is selected in CAS Signaling Group-line > Signaling Tab

• Verify that Call Services are selected in Line Circuit Routing Group-phone > Call Services Tab

Change Change Fax Relay from T.38 without Fallback to G.711

• Make sure that Fax Relay is set to G.711.

  Info
  The codec should be either G.711U or G.711A depending on your particular environment.

• Enable both, Fax Relay and Fax Modem Coding:
  • Fax Relay: This command configures how the Tenor signals the other end to tell the peer how to switch over to the correct protocol for a fax call. When FaxRelay is set to anything other than 0, there will be a short delay in training as the Tenor determines whether the device at the other end is a fax machine or a modem
  • Fax Modem Coding: Enable the Fax Modem Coding configuration option if the Tenor will be used to make modem calls (remote door/elevator control).
    When the Tenor is configured for modem over IP calls, FaxModemCoding allows you to select which codec will be used.
    When FaxRelay is set to 0 (Disabled), Modem over IP (MoIP) takes over, and all fax calls will be sent as MoIP passthrough with the codec specified by the FaxModemCoding setting.
    When FaxRelay is set to anything other than 0, there will be a short delay in training as the Tenor determines whether the device at the other end is a fax machine or a modem.

Configuring the Relay of Calling Name (CNAM)

The configuration of the Calling Name (CNAM) is optional. Tenor can relay CNAM in both directions Analog to SIP and SIP to Analog.

Troubleshooting Techniques

Troubleshooting FAX Calls Between the Tenor and PSTN

• If you are getting comm errors on the Fax machine, check the following resources for solutions:
  • comm error 350 - disable ECM
  • error codes 242,346,321,344,388,283 - The first 2 settings you want to change are the error correction (ECM) and v.34 these are on by default you would want these off.

• If faxes are failing, check the E1 port counters for slips and frame errors.

• The frame errors and the slips counters must not be increasing. You can check if they are increasing by resetting the counters. If the errors are increasing, the issue could be caused by one of the following:
  • System timing / clocking. Check the clock source (System -> System Timing) - it should be set to Network/T1/E1 port and not System/Free run. If the clock source is set to Network, but the Current Active Clock shows as Free run, click Apply and ensure that Current Active Clock is now set to Primary. This should resolve the clocking issue as long as the error counters do not increase.
  • If the Tenor is not configured to register with theSBC local SIP registrar and the SIP Signaling group inSBC constantly goes down, check the contents of the var_config.cfg file (from Tenor Config Manager -> Tools -> Var_config -> Edit) and delete the line specifying the transport protocol as in P108 it is obsolete.
  • Bad E1 cable. Replace the cable.
  • Faulty RJ45 jacks. Replace the cable or fix the Rj45 jacks.
  • Faulty RJ45 socket. Try configuring a different T1/E1 port. Visually check the pins in the E1/T1 ports for any differences.
