How To Interconnect Multiple UCM6510 IPPBX Page 5 of 8
If the status of the trunk displays “Unreachable” it means that UCM6510-A and UCM6510-B are unable to
reach each other. In this case, please ensure physical connectivity of both devices. Please also verify that
from the UCM6510-A network, the UCM6510-B is responding to ping and vice versa.
Note:
The steps below will need to be performed on the UCM6510-B as well. When configuring UCM6510-B, set
the peered SIP trunk host name as UCM6510-A
’s IP address or domain name.
CONFIGURE OUTBOUND RULE ON UCM6510
On the UCM6510-A web GUI, go to
PBX
->
Basic/Call Routes
->
Outbound Routes
to create a new
outbound rule. This would allow the extension on the UCM6510-A to reach extensions on UCM6510-B.
Here’s what to configure:
Calling Rule Name: This is for reference purpo
ses so we chose to use “toUCMB”.
Pattern: the pattern used in this example is 1XX since the UCM6510-B is using an extension range of
100-199.
Privilege Level: configured as “Internal”. This can be changed to regulate which users can make
outbound calls through this particular route.
Use Trunk: select the SIP Peer Trunk UCM-A.
Click on “Save” and “Apply Changes” on the top of the web page
.
