SIP Routing With boberdoo Slashes RTB Call Costs

Written by Scott Hettman | February 25, 2026 5:30:01 PM Z

You are likely paying too much to route calls to your Real-Time Bidding (RTB) buyers. Traditional call routing platforms often mark up wholesale rates, positioning this as the "cost of doing business." It’s not.

boberdoo's call routing platform integrates your own Twilio credentials directly into the lead system. This means you pay Twilio directly for usage instead of subsidizing a vendor’s profit margin. When your buyers support SIP integrations, you can route outbound calls through SIP trunking instead of standard programmable voice, reducing routing costs by more than 90% while preserving your routing intelligence.

The Economics of SIP vs. Standard Voice

The price difference between standard voice and SIP termination is huge for high-volume operations.

SIP Termination

Note for High-Volume Operations: If you are a truly high-volume caller, you can negotiate even lower rates. Twilio offers commitment-level discounts if you commit to specific spending levels; these are negotiated directly with Twilio to further increase your margins.

Why Lead Sellers Choose SIP for RTB

RTB relies on volume and millisecond-level speed. SIP termination delivers the same routing speed at a fraction of the cost. It doesn’t slow down your auctions or compromise Earnings-Per-Lead (EPL) calculations.

Many buyers in the industry, including those using Ringba, already have SIP infrastructure. Since Ringba natively supports SIP reception, selling into their network via SIP is a "low-hanging fruit" opportunity for immediate savings. boberdoo allows you to optimize for each buyer individually, routing via SIP to those who support it and via standard voice to those who don’t.

How It Works in boberdoo: A 3-Step Overview

Implementing SIP routing doesn't require a technical overhaul. It is a backend configuration change that follows these steps:

  1. Obtain Credentials: Get the SIP URI and necessary credentials from your buyer.
  2. Configure Delivery: Enter these credentials into the Custom Delivery section of your boberdoo system.
  3. Automatic Routing: boberdoo automatically switches the outbound leg to SIP for that specific buyer while maintaining all your existing RTB logic, filters, and tracking.

SIP Implementation Without Disruption

Adding SIP termination doesn't mean giving up functionality. You keep the smart distribution, unified budget management and real-time analytics you depend on.

Active campaigns continue without interruption. Your buyers won't notice a difference in call quality or connection speed; they receive the call through their existing infrastructure. The only noticeable change is the dramatic drop in your monthly telecommunications bill.

Optimizing Your Buyer Network

Smart lead sellers should audit their buyer network to identify SIP opportunities. Start by ranking your buyers by monthly call volume. Your top 10 buyers likely represent the majority of your volume.

Approach the conversation with a mutual-benefit mindset: reducing telecommunications costs for both parties creates room for improved economics that benefit your relationship. If a buyer doesn't support SIP, boberdoo handles them via standard voice, so you never have to choose between cost optimization and buyer relationships.

 

Call routing costs should not scale faster than your revenue. By integrating your own Twilio account and using SIP termination for buyers who support it, you can stop subsidizing your platform vendor's margin and keep that revenue for yourself.

For RTB operations, the choice is simple: route via SIP to save money when possible, and route via voice when necessary. Simple, transparent, and built for scale.
