2) Nodes can make local calls

3) Nodes can make calls to HQ

Alarm Information

We checked the calls by LMT, we found the following:

ecd9ff810430480983ae5108f1aad0c3

Handling Process

1) We checked the national and international prefix

- We re-configured the prefix for national and international

- Tested the calls we found any calls we start with 90 ( national prefix ) or 900 ( International prefix ) not working

2) We checked with LMT the number change is going fine

- We applied number change on the 90 and 900 prefix , to be the same end results as 9 ( local prefix ) , still no call is going out

- We confirmed that calls for national and international on HQ are working fine

3) We checked the user rights, and all have the national and international rights

4) We checked the configuration that needs to be done on the local node, following the guide as in the following link:

Solution

Modify the Trunkgroupno to support national and international, then assign the callsource for it in the local regeneration prefix, as in the guide steps :
