Hubsoft integration with Call Sys

About Call Sys

Call Sys is Espectra Tecnologia’s platform that brings together marketing, customer service, and sales, with IP telephony and multichannel chat in one place. WhatsApp service runs on GupShup, a Meta partner. In Hubsoft, the Call Sys gateway appears under the name Espectra Tecnologia.

What the integration does

Hubsoft has two integrations with Call Sys: one for PBX and one for messaging.

Calls (PBX):

• Triggers collection calls according to the billing method rules: after the invoice is generated, before the due date, after the due date, or after payment.
• Sends the call to an extension registered as a dialing option, within the integration’s time window.
• Click to Call: the agent calls the subscriber from the customer record, and the call is routed to their extension.

Messages (WhatsApp):

• Sends scheduled and automated WhatsApp messages with HSM templates, which are pre-approved messages for active outreach.
• Fills in the template variables with customer and invoice data.
• Routes the conversation to a team or a Call Sys bot flow, according to the configuration.
• Uses the templates in the SMS rules for the billing method and in messages sent to customer groups.

What you need

• A Call Sys account.
• The API URL, available in Call Sys under Documentation/API in the user menu. Use only up to ".br".
• The API token, under Settings > Company > Edit > Integration.
• The extensions, under Telephony > Extension.
• For WhatsApp: the bot configuration ID (Chat > ChatBot), the team ID (Settings > Team) or bot flow ID (Chat > Bot Flow), and the templates under ChatBot > TemplatesWhatsapp.

How to activate

1. In Hubsoft, go to Settings > Integrations > PBX, click Add, and select the Espectra Tecnologia gateway. Enter the URL, token, and start and end times.
2. Under Actions > Dialing > Add, register the extension and indicate whether it is active.
3. For WhatsApp, go to Settings > Integrations > SMS/Messengers, add the Espectra Tecnologia gateway, and enter the parameters.
4. Under Actions > HSM Template > Add Template, enter the template name, description, and variables.
5. Configure the rules in the Call and SMS tabs of the billing method, along with the sending routines.

The step-by-step instructions, including the screens, are available in the Hubsoft wiki: PBX with Call Sys and messaging with Call Sys.

Limitations

• Calls are routed only to extensions registered as dialing options.
• On WhatsApp, messages can be sent only with an HSM template. Therefore, this integration does not support one-off messages or the Subscriber Portal.
• Routing to a team and to a bot flow cannot be used at the same time.

Frequently asked questions

Can I customize WhatsApp messages?

Yes, with variables in the HSM template. They are replaced with customer data when the message is sent.

My HSM template does not work. What should I check?

Check whether the data is filled in Hubsoft exactly as it is in Call Sys and whether the template is approved for use on the platform.

The Click to Call button does not appear. What could be the issue?

The Click to Call extension is missing from the user parameters under Settings > General > Users > Actions > Edit > Parameters.
