Running successful outbound campaigns requires flexibility and control — whether you’re using SIP Caller as a predictive dialer, progressive dialer or power dialer. With our latest update, SIP Caller introduces several powerful features that make campaigns smarter, more efficient, and more adaptable to your specific goals. These improvements help teams reach more customers, reduce missed opportunities, and optimize how call retries are handled.

1. Number Priority: choose between retrying pending calls or prioritizing new numbers

Campaigns now include a new “Number Priority” setting, allowing you to decide how SIP Caller should prioritize calls during a campaign.

• Retry Pending: SIP Caller will prioritize numbers that have already been called but need to be retried. For example, if a previous attempt was unanswered, SIP Caller can start retrying those numbers before moving on to new ones.
• Not Contacted: SIP Caller will focus on new numbers first. Every number in your list will be called at least once before any retries begin.

This new option gives you control over your campaign’s pacing strategy — whether you want to maximize the chances of reaching previously unavailable contacts, or ensure full initial coverage of your contact list before retrying.

2. Send DTMF tones automatically to navigate IVRs

We’ve added support for DTMF tones, enabling SIP Caller to handle IVRs (Interactive Voice Response systems) automatically.

When calling business phone numbers, it’s common to encounter menus that require key presses to reach the right person or department. Previously, such calls were considered answering machines and would fail. Now, SIP Caller can automatically send tone sequences and pauses to navigate through these IVRs.

For example:

+18005550001p2p456

Each p represents a 2-second pause. In this case, SIP Caller will:

1. Dial +18005550001
2. Wait 2 seconds
3. Press 2
4. Wait another 2 seconds
5. Press 456

You can include as many pauses as needed, giving you complete control over how SIP Caller interacts with IVR systems to reach your target contact.

3. Multiple phone numbers per record

Another major improvement is the ability to define multiple phone numbers per record.

Previously, each record contained a single phone number:

Number,CustomerName,Balance
18005550001,John Doe,$200
18005550002,Jane Doe,$100

Now, you can specify up to five phone numbers separated by semicolons:

Number,CustomerName,Balance
18005550001;18005550011,John Doe,$200
18005550002;18005550012,Jane Doe,$100

If the first number cannot be contacted, SIP Caller will automatically try the next one. Once all numbers are attempted, SIP Caller will start again from the first one according to your retry rules.

This is especially useful for businesses where a contact may have multiple reachable numbers — mobile, office, or alternate lines — increasing the chances of a successful connection.

Smarter campaigns, better results

These updates make SIP Caller even more powerful and adaptable for your call campaigns — whether you’re running customer service follow-ups, appointment reminders, or large-scale outreach programs.

Stay tuned — more enhancements are on the way to help you make every call count.
