Connect TeleCMI and Slack

TeleCMI handles your business phone numbers, routing and call records. FlowMattic sends call events to Slack: missed calls for whoever is free to call back, a waiting caller when the queue backs up and each agent's own missed calls by direct message. For sales and support teams who answer phones and chat in Slack.

1. TriggerIncoming Missed CDR

When TeleCMI fires Incoming Missed CDR, FlowMattic runs Send Channel Message in Slack with the data from that event.

You build this in the FlowMattic workflow builder on your own site. See the setup steps

TeleCMI and Slack workflows you can build

Each one uses only triggers and actions the two integrations ship today, plus FlowMattic's own tools. Where the library has a ready-made template, import it instead of building from scratch.

Ready-made template

Post every missed incoming TeleCMI call to Slack

Each missed call posts the caller's number and the number they dialled, so the first person free can ring back before the caller tries someone else.

Incoming Missed CDRSend Channel Message

View the template

DM each agent the calls they missed

A Lookup Table maps the agent's TeleCMI user to a Slack user ID, and Send Direct Message tells that agent about their own missed call to return.

Incoming User Missed CDRLookup TableSend Direct Message

Warn the team when a caller is waiting

Incoming Waiting Leg A fires when a call hits your virtual or toll-free number. A post in the support channel tells someone to pick up while the caller is still holding.

Remind reps to retry outgoing calls nobody answered

When an outgoing call is missed, Add Reminder sets a retry for the rep later in the day, so prospects who did not pick up get a second attempt.

Outgoing Missed CDRAdd Reminder

Log answered calls in a private team channel

Answered calls post the caller, agent and duration to a private channel, giving the team lead a running call log without exporting reports.

Incoming Answered CDRNumber FormatterSend Private Channel Message

Send after-hours missed calls to the on-call phone

Date/Time Formatter reads the call time and a Router sends calls outside office hours to the on-call engineer by DM, while daytime calls go to the channel.

Set up: missed calls to Slack

At the end, every missed incoming call on your TeleCMI numbers posts the caller and the number dialled to a Slack channel.

Triggers and actions in this pair

A trigger starts a workflow. An action is something FlowMattic does in the app as a step.

Good to know

CDR triggers fire once the call is over and its record is written. Leg A and Leg B triggers fire during the call, which is what you want for a waiting-caller alert.
Incoming Missed CDR covers calls nobody answered, and Incoming User Missed CDR covers calls a particular user missed. Using both can post the same call twice.
Field names come from TeleCMI's call records, so the mapping above is an example. Capture one missed call before building the Lookup Table.

Why run this pair with FlowMattic

TeleCMI and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.

Missed calls get returned

Callers who could not get through reach a person in Slack, with the number ready to dial back.

Agents own their callbacks

Direct messages for each agent's missed calls make it clear who is calling back, instead of everyone assuming someone else will.

Every call, no per-task fee

FlowMattic runs on your own WordPress site with unlimited runs, so a busy phone line adds nothing to the automation cost.

Common questions

How do I get TeleCMI missed call alerts in Slack?

Create a FlowMattic workflow with the TeleCMI Incoming Missed CDR trigger, follow its instructions to send call records to the workflow, then add Slack Send Channel Message with the caller and dialled number.

Can answered calls create a lead in my CRM?

Yes. Start from Incoming Answered CDR, add your CRM's step, for example creating a lead in Zoho CRM, and post a short summary to Slack after it.

Can I see outgoing call activity too?

Yes. Outgoing Started, Outgoing Answered and Outgoing Hangup are triggers, and Outgoing Answered CDR and Outgoing Missed CDR fire once the call record is written.

Can missed calls for each number go to different teams?

Yes. Add a Router on the dialled number, so calls to the sales line post to sales and calls to the support line post to support.
