What are the Internet bandwidth requirements and policies?

Because your voice calls with be traversing the Internet, you want to be sure that you have enough bandwidth to support the number of expected concurrent calls.  You also want to understand the policies of the vendor.  Some vendors require that you purchase Internet connectivity from them, while others, like SIP.US, let clients select the bandwidth that provides the best quality and value in their area.

What is being done to protect you against toll fraud?

Toll fraud is an increasingly prevalent problem in the entire telecommunications industry as malicious actors invent new ways of stealing money from business, often through unauthorized international calling. Ask any vendor you consider to verify that they have automated systems in place to detect toll fraud and protect their SIP trunks.

What are the contract terms and cancellation policies?

Every provider is different, so before you connect to a SIP trunk, be sure understand under which conditions you can cancel and the term of any obligation.

Does the vendor offer telemarketing support?

If you have a large volume call center or operate a telemarketing organization, you’ll want to take special care to consider the provider’s terms of use around these activities.  Some SIP vendors are not equipped to handle this type of traffic and can charge significant surcharges based on this type of use.  A few vendors, including SIP.US welcome this traffic, but you’ll want to be certain.

Is your PBX supported?

Does the service meet your international calling needs?

If you need international DIDs, make sure the vendor can provide them and be sure to understand the rates and terms.  If your DIDs will all be local, but you make a lot of international calls, be certain you understand the rates and any limitations.

Does your router support QoS?

None of these considerations is technically complex and every reputable SIP trunking vendor should be able to answer each question quickly and clearly.  Getting the answers before you connect to a SIP trunk will make your transition as easy as possible and you’ll be able to start enjoying the advantages of SIP right away.
