Firmware Version 1.0.1.25
This is the initial version.

Firmware Version 1.0.1.25 Configuring UCM6100 Series with HT503 Page 4 of 18
OVERVIEW
This document describes basic configuration to interconnect UCM6100 series and HT503. This is typically
applied to the scenario where users would like to add a HT503 not only as a remote extension but also as
an external PSTN trunk. It could be common that we prefer to grab a PSTN line from another PBX or a
PSTN line in a remote location, but we don't want to invest too much on a FXO gateway.
There are two ways to set up the UCM6100 series IP PBX with the HT503.
Method 1: Register the HT503 to the UCM6100 directly.
Method 2: Configure HT503 as a SIP peer trunk.
Warning:
When the UCM6100 series is interconnected with other HT503, it is NOT recommended to turn on
"Allow Guest Calls" under the UCM6100 web GUI->PBX->SIP Settings->General. Turning on this
option will allow unauthenticated calls coming through the UCM6100 series. Please be aware of
the security concerns when using this option.
When using the IVR in UCM6100 series, please be aware that if "Dial Trunk" option is turned on in
IVR settings, the call into the IVR will be able to dial outbound call using UCM6100's trunk. The
IVR's permission level will be used when making outbound calls in this case. Please select proper
permission level for the IVR to control the outbound calls allowed via "Dial Trunk".

METHOD 1: REGISTER HT503 TO UCM6100
Create Extension on UCM6100
On the UCM6100 web GUI, create two extensions under PBX->Basic/Call Routes->Extensions. These
two extensions are used for HT503 FXS and FXO registration.
The password for the extension will be randomly generated if not specified.
Figure 1: Method 1 - Create Extension 5000 on the UCM6100
Figure 2: Method 1 - Create Extension 5001 on the UCM6100
Create IVR on UCM6100
On the UCM6100 web GUI, create an IVR extension under PBX->Call Features->IVR. This is to receive

Firmware Version 1.0.1.25 Configuring UCM6100 Series with HT503 Page 6 of 18
the calls forwarded from the HT503.
In IVR settings, if "Dial Other Extensions" is enabled, the calls forwarded to the UCM6100 IVR will be able
to reach the internal extensions registered to the UCM6100. Also, you can assign the "Key Pressing
Event" to different destinations.
Figure 3: Method 1 - Create IVR 7000 on the UCM6100
Configure FXS Port on HT503
1. Connect an analog phone to the HT503 FXS port.
2. On the HT503 web GUI, go to FXS Port setting page, configure to register the FXS port to the

Firmware Version 1.0.1.25 Configuring UCM6100 Series with HT503 Page 7 of 18
UCM6100 extension 5000. Please refer to the highlighted settings in the following figure.
In this example, the UCM6100 IP address is 192.168.40.207.
Figure 4: Method 1 - Configure FXS Port on the HT503
Configure FXO Port on HT503
1. Connect the PSTN line to the HT503 FXO port.
2. On the HT503 web GUI, go to FXO Port setting page, configure to register the FXO port to the
UCM6100 extension 5001. Please refer to the highlighted settings and other necessary settings in the
following figures.
In this example, the UCM6100 IP address is 192.168.40.207.

Firmware Version 1.0.1.25 Configuring UCM6100 Series with HT503 Page 8 of 18
Figure 5: Method 1 - Configure FXO Port on the HT503: Registration
Since we are going to use IVR when the call is forwarded to the UCM6100, the UCM6100 will need to be
able to detect the DTMF digits. Configure the HT503 FXO port DTMF settings as below as an initial setup.
Figure 6: Method 1 - Configure FXO Port on the HT503: DTMF Settings
There are a few necessary changes to be made in FXO termination section and Channel Dialing section
as well.

First we should confirm which method the PSTN line is using. If the PSTN line is using current
disconnect (typical case in North America), then we should turn on "Enable Current Disconnect" and
disable "Enable PSTN Disconnect Tone Detection".
The default "Current Disconnect Threshold" is 100ms, but if you start experiencing dropped calls then
you should raise this value by 100ms intervals.
If the PSTN disconnects using the tones method, then turn on "Enable PSTN Disconnect Tone
Detection" and turn off the "Enable Current Disconnect" option.
For PSTN tone detection, the tone disconnect method is widely used everywhere else in the world.
The North American busy tone value is "f1=480@-32,f2=620@-32,c=500/500" but these tones vary
from country to country. You may look up for the settings for your country at www.3amsystems.com or
download the information from http://www.itu.int/ITU-T/inr/forms/files/tones-0203.pdf.
Set "Number of Rings" option to 1. If you happen to experience caller ID issue, you may set it to 2.

Firmware Version 1.0.1.25 Configuring UCM6100 Series with HT503 Page 10 of 18
Set "PSTN Ring Thru FXS" to "No" if you prefer not to ring the FXS port after the Ring Thru Delay. In
the sample setup, it's set to "Yes".
Set "PSTN Ring Thru Delay" option to 1. If you happen to experience caller ID issue, you may set it to
2.
Set the "Stage Method (1/2)" to 2 for 2 stage dialing.
Figure 8: Method 1 - Configure FXO Port on the HT503: Channel Dialing
Configure Unconditional Call Forward on HT503
On the HT503 web GUI, go to Basic setting page, configure "Unconditional Call Forward to VOIP" to the
IVR extension on the UCM6100. In this example, the UCM6100 IP address is 192.168.40.207.
Figure 9: Method 1 - HT503 Basic Settings
How to Dial
Once the HT503 and the UCM6100 are set up as above, the inbound call and the outbound call will be
working as described below.
Outbound call
The extension registered to the UCM6100 can dial the HT503's FXO extension number (5001 in this
example). After you get the second dial tone, you can then dial a PSTN network number. Basically, the
outbound call is done in a 2-stage manner.
Inbound call
The user from outside network can dial into the PSTN line's number (connected to HT503). And then
he/she will reach the IVR of the UCM6100. The IVR on UCM6100 would allow the user to further enter
extension number or key pressing digit to reach the desired destination.

Firmware Version 1.0.1.25 Configuring UCM6100 Series with HT503 Page 11 of 18
METHOD 2: Connect UCM6100 to HT503 Using Peer SIP Trunk
Create Extension on UCM6100
On the UCM6100 web GUI, create one extension under PBX->Basic/Call Routes->Extensions. This
extension is used for HT503 FXO registration.
The password for the extension will be randomly generated if not specified.
Figure 10: Method 2 - Create Extension 5000 on the UCM6100
Create IVR on UCM6100
On the UCM6100 web GUI, create an IVR extension under PBX->Call Features->IVR.
In IVR settings, if "Dial Other Extensions" is enabled, the calls dialing into the UCM6100 IVR will be able to
reach the internal extensions registered to the UCM6100. Also, you can assign the "Key Pressing Event"
to different destinations.

Configure Outbound Rule on UCM6100
On the UCM6100 web GUI, go to PBX->Basic/Call Routes->Outbound Routes to create a new
outbound rule. This would allow the extension on the UCM6100 to reach numbers in PSTN network via the
peer SIP trunk we just configured.
Figure 13: Method 2 - Configure Outbound Rule on the UCM6100

Firmware Version 1.0.1.25 Configuring UCM6100 Series with HT503 Page 14 of 18
In this example "91XXXXXXXXXX", 9 is the first dialing digit and it will be stripped off when the call goes
out.
Configure Inbound Rule on UCM6100
On the UCM6100 web GUI, go to PBX->Basic/Call Routes->Inbound Routes to create a new inbound
rule.
In this example, we create the DID as 20000, which will be used in the HT503 call forward setting.
Figure 14: Method 2 - Configure Inbound Rule on the UCM6100
The default destination is configured to IVR.
Configure FXO Port on HT503
1. Connect the PSTN line to the HT503 FXO port.
2. On the HT503 web GUI, go to FXO Port setting page, configure to register the FXO port to the
UCM6100 extension 5000. Please refer to the highlighted settings and other necessary settings in the
following figures.
In this example, the UCM6100 IP address is 192.168.40.207.

Once the HT503 and the UCM6100 are set up as above, the inbound call and the outbound call will be
working as described below.

Firmware Version 1.0.1.25 Configuring UCM6100 Series with HT503 Page 18 of 18
Outbound call
The extension registered to the UCM6100 can dial prefix + PSTN number to reach outside numbers in
PSTN network, as defined in UCM6100 outbound route.
Inbound call
The user from outside network can dial into the PSTN line's number (connected to HT503). And then
he/she will reach the IVR of the UCM6100. The IVR on UCM6100 would allow the user to further enter
extension number or key pressing digit to reach the desired destination. The inbound call will go
through the inbound route set up on the UCM6100.
