Frequently Asked Questions

Q: What type of service does Rapidvox provide?

  • Rapidvox provides dedicated and optimized transit of your voice-over-IP telephone calls to Tier-1 telecom carriers. There are no monthly rates and no contracts... we are strictly a "Pay-As-You-Go" provider.

Q: Is your service an inbound service, outbound service or both?

  • Rapidvox offers speedy transit of your voice calls to regular destinations on the Publically Switched Telephone Network (PSTN). At present, we do not offer incoming (DID) service.

Q: Do you offer service to A-Z destinations?

  • We have the ability to deliver your call to any corner of the globe. For the security of our clients, we do restrict access to a handful of premium destinations including but not limited to satellite connections (INMARSAT) and pay-per-use entertainment services.

Q: What equipment do I need to use with Rapidvox?

  • Clients requiring the most flexibility may use our service with the Asterisk, TrixBox or FreeSwitch platforms that use the SIP or IAX2 protocol. For those clients who require less frequent use of our service they may opt for a PC-based softphone or SIP ATA adaptor, which connects their regular telephone to our service.

Q: What if I don't have a PBX or SIP hardware, can I use a software phone on my PC?

  • Yes. Our service allows the use of a PC "softphone". Simply download the latest ZoIPer softphone, install and follow the simple set-up instructions in our members area. You will require a headset or microphone to use the softphone.

Q: Can I use my iPhone, smartphone or other mobile device?

  • Yes. As the configuration of these devices depends on which particular device and/or app you are using, we provide basic configuration to get you started.

Q: What protocols does your service use?

  • Rapidvox makes use of the IAX2 and SIP protocols. Clients using SIP hardware or telephones must use the SIP protocol. Clients running Asterisk or related software may utilize either protocol, however SIP is highly recommended.

Q: What audio codecs do you support?

  • Rapidvox supports the use of G.711, GSM, G.729 and iLBC audio codecs. To benefit from the greatest sound quality, we recommend that our clients use G.711. If bandwidth is a consideration, one of the high-compression codecs may be the best option. However due to their nature, high-compression codecs will increase your call latency and lack the clarity of other codecs.

Q: Is there a limit to the number of simultaneous calls I can place?

  • In short, no. The amount of simultaneous calls that can be made is dependent on the balance in your account. At the beginning of each call, up to two-hours of credit at that calling rate is held in-escrow by our system. A second and simultaneous call will attempt to hold another two-hours of credit in-escrow and so forth. At the conclusion of each call, any remaining credit is released back to your account for re-use.

Q: How do I start using your service?

  • We have made the process quite simple. Simply register, place funds in your account, configure your equipment and start sending calls. You can start with as little as $5.00 USD to try our services.

Q: How do I fund my account?

  • We accept funding from PayPal verified members. For those clients with larger-volume voice transit needs, you may also fund your account via bank wire-transfer.

Q: I have a question that is not covered by this FAQ.
