issue with frowarding when the call is coming from an external user

Publication Date:  2018-08-28 Views:  175 Downloads:  0
Issue Description


Assuming we have a basic user, new extension number 5000 configured on a U1981.

We have registered this number with CFU to an external mobile number. When an internal party calls to 5000, the forwarding is being done. However, when an external party calls to 5000, the forwarding is not working.


Handling Process

1. Verified if the forwarding is done correctly



2. Collected the debug logs and analyzed what is happening when the external call is trying to be forwarded:


- based on the collected logs  there was a permission missmatch between the trunkgroup and prefix.

 The prefix permission is DDD and CUS1, but the trunkgroup is ‘local/inter’ and ‘cus32’. 

2. Change the group trunk feature:

config modify trunkgroup no 703 restrict yes outgoingright inter&local&cus32&ddd&cus1

3. Retried and the issue was no longer persistent.


Root Cause

VerifiedThe forwarding was not possible because of the trunk restriction on which the external calls where coming in.

Solution

Changed the trunk priority.
