    Patch-through calls

    Connect thousands of voters to key decision makers.

Patch-through calls

Most effective way to bring change

Use patch-through calling campaigns when you need to drive hundreds or even thousands of calls to elected officials. Connecting supporters to key decision makers is one of the most effective ways to bring attention to the issues. Patch-through calling is 42% lower in costs than email marketing.


Live Phone Call Monitoring

Stay on the call while the voter talks to the decision maker. Your call is on mute.

Unlimited Volunteers

Volunteers are crucial to your campaign. Recruit as many as you need, for free! We do not charge per seat in a campaign.

Scripts and Surveys

Add a calling script and survey for every campaign. Train your agent on the script and collect information on the call and the progress. The results are synced directly into your CRM.

Call from anywhere

Recruit volunteers from around the city or even world and put them to work. Volunteers can make calls for a campaign from anywhere in the world, right from their browser. Browser calls cost the least. They can even make calls from their phone or soft phone.

Volunteer management

Create an unlimited number of teams and organise your volunteers into these teams. Assign a team to a advocacy campaign instead of individual volunteers.

Surveys responses and Analytics

Forget pen and paper. Use CallHub's advanced survey tool and get digital responses instantly. Use advanced analytics platform to evaluate your calling campaign.

Step 1: Call Supporters

Step 2: Tell them the script

Step 3: Patch them through to decision makers

Actively connect supporters to decision makers

How it works

Build a team of volunteers to call supporters and talk to them about the issues. Let the volunteer guide and practice the script with the supporter. Once they're prepared, connect the supporter to the representative, all the while staying on the call. Once the call is complete, the volunteer can connect the supporter to another representative if needed.
