Overview

You may notice that one of your subscriber numbers is not receiving any messages. 

Solution

1. This issue is likely caused because there is no GTT rule defined for the SCCP Called Party Digits: <number> which is not receiving any messages. You can review all the GTT rules that are defined for your system in the host-specific configuration files.
2. For instance, if the subscriber number that is not receiving any messages is 1111111111, please ensure that the host_config.txt file has a gttrule such as the following:
   <gttrule inputgtaddressinfo="1111111111">
3. Please note that you can use the * operator to set one rule to point to multiple subscriber numbers if they are similar. E.g. for 111111111 and 1111122222 you can use the rule
   <gttrule inputgtaddressinfo="11111*>
4. Please note that the inputgtaddressinfo is a mandatory attribute of gttrule, but if your existing rules have other attributes such as inputgtnatureofaddressind, inputsubsystemnumber etc. make sure to include them in the newly configured rule as well.
5. Make this change in the host_config files across all your RTRs. Once the update is done, restart each RTR, one at a time, executing the following commands -
   

   tp_config --validateonly
   tp_stop
   tp_start
   tp_status

Testing

If the issue still persists, please contact support and include the following information: 

• output from tp_walkall
• syslog files from your RTRs
