Result
- A messaging channel is created successfully. You can see the channel displayed in the Messaging Channel list with Status showing .
- PBX automatically tracks and records the number of messages sent
and received on the channel, where the Total column
indicates the total number of sent messages, including both successfully
sent messages and failed ones.Note:
- For sent messages, PBX only tracks the number of the messages sent from agents' Linkus UC Clients. If you want to calculate the actual cost of sent messages, consult with the SMS service provider for the precise number of messages transmitted, as long text messages (longer than 160 characters) are automatically split into segments and then re-assembled when they are received, increasing the number of sent messages.
- You can filter the statistics by a time period using the time filter.
What to do next
Send text messages to the phone number and see if the specified agent can receive messages on his or her Linkus UC Client.
