...

The option allows setting a specific GSM gateway for SMS sending for each separate user:

• Edit the config file /etc/wildix/smsd-route.conf by specifying user extension and MAC address of GSM gateway, for example:

  Code Block

...

Dialplan

Exit code 0 from voicemail 

...

...

• Create a new config file template.conf including GTM ID in the file /rw2/etc/pbx/, for example, use the command: 

  Code Block
  echo 'gtm=GTM-12345678' > template.conf

  where 123445678 is Google Tag Manager ID.

...

Users

2 PBXs in WMS Network, each with its own Active Directory for users

To make it work, proceed as follows:

1. Make import of users via Active Directory on Server PBX
2. Access Client PBX and move users from Server PBX to Client PBX
