Contact centers require stable capacity, high-quality connectivity, and fully compliant routing for both inbound and outbound traffic. With Tellimon, outbound calls are delivered through local termination, ensuring correct caller ID display, better answer rates, and protection against blocking on international routes.

Tellimon is strongly positioned to support enterprise call centers, BPOs, sales teams, and customer service operations. Leveraging our experience and close collaboration with global carriers, we follow clear guidelines to ensure reliable service and regulatory compliance.

Outbound Calling Guidelines for Contact Centers

⚠ Restricted Traffic Types

The following outbound traffic categories are not supported and will be blocked upon complaint:

• Investment schemes

• Cryptocurrencies

• Gambling or betting

• Adult services

• Lotteries (in any country)

Valid & Reachable Caller IDs

Outbound calls must present the actual Tellimon DID assigned to you.
This number must:

• Be active on our platform

• Connect to a human agent or an IVR/announcement when dialed back

• Not contain commercial or misleading content

 Live Calling Only

Outbound traffic must be fully live.
Pre-recorded advertising messages or automated announcements are not allowed.

Dialer Traffic & Call Behavior

Mass automated dialer traffic is not supported.
Call patterns must reflect natural, human-driven dialing.

We actively monitor:

• ASR (Answer Seizure Ratio)

• ACD (Average Call Duration)

• CPS (Calls Per Second)

If unusual patterns appear, we will contact you to adjust.
In cases of ongoing excessive or non-corrected behavior, we may limit or block outbound traffic.

Note: Many regulations define a call as abandoned if a live agent does not take the call within two seconds after the callee finishes greeting.

 Allowed Call Times

Outbound calling should be limited to 8:00 AM – 9:00 PM local time, unless different rules apply according to the local regulator.

Respect Do Not Call (DNC) Lists

Customers must comply with national Do Not Call registries where applicable.

Stay Compliant in Every Country

Regulations vary by region. Updated details for each country—including required documents, traffic rules, and capacity limits—can be found in our product sheets and coverage documentation.

Tellimon ensures your contact center operates smoothly, compliantly, and with guaranteed high-quality voice performance.
