OVERVIEW
This document describes basic configuration to interconnect UCM6100 series and FreePBX via SIP
register trunk. Once properly configured, the extensions on both PBX can securely make calls to each
other.
Warning:
When the UCM6100 series is interconnected with other PBX, it is NOT recommended to turn on
"Allow Guest Calls" under 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 call allowed via "Dial Trunk".
There are vast deployment possibilities when peering and interconnecting PBX systems. Due to
highly customizable nature of both the UCM6100 series and FreePBX, please use this tutorial as a
basic sample to get UCM6100 series work with the FreePBX. The actual implementation may be
customized and different from this basic configuration.

CONFIGURING SIP TRUNK
Create Extension on UCM6100
On the UCM6100 web GUI, create an extension under PBX->Basic/Call Routes->Extensions. This
extension is used for FreePBX to register SIP trunk to the UCM6100.
The password for the extension will be randomly generated if not specified.

Configure SIP Trunk on FreePBX
1. On the FreePBX web GUI, go to trunk setting page to create a SIP trunk. Then configure the following
in Outgoing Settings section of this trunk.
Figure 2: FreePBX Trunk - Outgoing Settings
Note:
secret=trunkpassword
Please use a secure password to replace "trunkpassword" as the actual password for the
FreePBX to authenticate UCM6100.
fromdomain=ucm_ip_or_domain
Please replace ucm_ip_or_domain with the actual IP address of host domain of the UCM6100.
remotesecret=xcoFhGEY4jdbHj
This is the password of the extension created on UCM6100 in section [Create Extension on
UCM6100].
2. On the same trunk setting page, configure the registration string so that the FreePBX can register the
SIP trunk to the extension created on UCM6100 in section [Create Extension on UCM6100].
This is the registration and
authentication information for
the UCM6100 to register SIP
trunk to the FreePBX.
This is the authentication
information used on the
FreePBX when there is
authentication request from
the UCM6100.

Figure 3: FreePBX Trunk - Registration
The registration string has the following format:
extension:password@ip_or_domain
Please make sure the registration information here matches the extension information (extension,
password, IP or domain address) on the UCM6100.
Configure SIP Trunk on UCM6100
1. On the UCM6100 web GUI, go to PBX->Basic/Call Routes->VoIP Trunks to create a new SIP trunk
using "Register SIP Trunk" type.
Figure 4: Create Register SIP Trunk on the UCM6100
2. Configure the following information for this trunk so that the UCM6100 can register to the FreePBX
trunk we just created.

The other fields in the above figure are optional.
From Domain: Configure the FreePBX IP or domain address.
From User: Same as username, i.e., freepbxtrunk.
Configure Call Routes on FreePBX
1. On the FreePBX web GUI, go to outbound route setting page to create an outbound route for the SIP
Password is trunkpassword
as we created in FreePBX.

trunk.
Figure 6: Configure Outbound Route on FreePBX
2. The FreePBX uses DID for inbound route by default. Therefore the extensions on the UCM6100 can
directly reach the extensions on the FreePBX. There is no additional configuration required for
inbound route as a basic configuration sample.
Configure Call Routes on UCM6100
1. 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 extensions (5xx, in this
example) on the FreePBX.

2. On the UCM6100 web GUI, go to PBX->Basic/Call Routes->Inbound Routes to create a new
inbound rule.
