1. Value
When talking termination, price and value are closely locked. Your termination provider decides which routes your calls go over, pays for that service, and bills you a markup. Low cost routes are often low quality. So very cheap termination providers are likely going to provide terrible audio quality, the kind that makes you hang up and try again and again but never gets better. The quality of your provider’s peering partners (the carriers it uses to route calls outside of it’s own network), has the biggest impact on your outbound call audio quality.

2. Security
Outbound toll fraud is a serious risk to your organization. Find a provider that protects your bottom line with customizable restrictions to outbound call access. IP authentication, which you can employ if your users are connecting from behind a static IP address, is one way to add a level of security. Rate and destination restriction also limit the damage fraudsters can inflict with your account credentials by blocking high-cost calls.

3. Infrastructure
The way your provider routes calls to the network also matters. If there are multiple layers to get through (your provider’s servers, their providers, and their providers’ providers…) your calls are subject to more risk in the form of transcoding and other potential handoff issues. Where your provider is sending calls is important too. If they have only one upstream partner, as opposed to a bank of reliable routes available, you’re out of luck if their one option fails. So it pays to know how your provider is sending out your outbound calls to the network.

Making it work:

If you can’t find a provider that give you what you need in origination and termination, you can absolutely use different carriers for each service. It’s a matter of configuring your PBX with the right rules. Some providers are better at one than the other, but for the sake of convenience of billing and account management, one provider that meets all of your needs is best (if you aren’t running your business as a service provider).

The upside of getting set up with multiple providers is redundancy. When carriers go down, it’s often termination or origination that goes off line, not always both at once. Having multiple providers configured on your system will make a switch easy if your primary connection ever goes down and you need to swap out quickly. Knowing your providers will help you build a hierarchy in your queue, so that you’re always using the best option available.
