5 Tips for Turning Up an Elastic SIP Trunk for Your Dialer

Turning up an Elastic SIP trunk looks different depending on the dialer setup involved. Jon Olson, QVD's Senior NOC Technician, walked through the three implementation types QVD's team sees most often.

Customer-controlled dialer with SIP experience

A company with a premise-based (on-site or cloud) dialer already using SIP, and full control over its own telecom decisions, is the easiest implementation — often just a matter of changing the IP address the dialer connects to, completed within 24 hours.

Bringing an Elastic SIP trunk to a hosted dialer (BYOC)

Most hosted dialer companies prefer to bundle telecom with their dialer seats, but Bring Your Own Circuit is an increasingly popular way to ensure calls are digitally signed and delivered with an A attestation. Because three parties are involved — the customer, the hosted dialer provider, and QVD — this can take one to six weeks depending on whether QVD has connected to that hosted dialer platform before (QVD has existing connections to Five9, Alvaria, CallShaper, Vici, and others). Customers pursue BYOC specifically to fix a low answer rate, blocked calls, or spam labeling, often because the built-in telecom provider signs calls with a B or C attestation rather than a direct A — many carriers won't sign with an A unless they have a direct Know Your Customer relationship with the actual dialer customer, not just the dialer company. QVD has invested in premium direct connections to Verizon, AT&T, and T-Mobile specifically to keep that A attestation intact from cradle to grave.

Legacy equipment

The third type is a premise-based dialer still running legacy TDM telecom. Bridging that gap to SIP requires identifying exactly what's in place today and mapping a clear conversion path.

Jon's 5 tips for a smooth turn-up

1. Set up an implementation call to review the current state, with your technical team present to do most of the talking.
2. If you use a hosted dialer, engage their team early — they may not move quickly on their own.
3. Test the connection on a setup separate from your production instance.
4. Schedule the actual move during non-production hours, with a continuously open call to avoid missed issues.
5. Retest during non-production hours immediately after the move.

With an Elastic SIP trunk, you don't need to worry about the number of trunks or concurrent call limits at all.
