BulkVS: A Bargain SIP Provider for Incredible PBX Platforms

Written on Jul 7, 2020.

At every opportunity I always tell new VoIP enthusiasts that one of the true advantages of switching to a VoIP platform is the fact that you don't have to put all your eggs in one basket. Just this morning, I read a Facebook post from one of the elders in my family lamenting the fact that her MaBell landline had failed in the midst of this week's snowstorm in North Carolina. Her local WiFi and cable TV still worked but not her landline or cellphone.

With that background, we are pleased to introduce BulkVS trunking as another option to add to your collection. Unlike Skyetel, ClearlyIP, Vitelity, and VoIP.ms, we receive no commissions from BulkVS so chalk this article up as a good example of biting off your nose to spite your face. There is a PayPal link to the right if you're feeling grateful.

Why does BulkVS matter? In the words of Alex Trebek, it's The 3 P's: Price, Price, and Price . An inbound US48 Tier0 phone number (DID) will set you back 6¢ a month with a 25¢ setup fee. And calls are billed at $.0003 per minute. Toll-free numbers in the U.S. and Canada are 14¢ a month with a per minute rate of $.0055. CNAM lookups are $.002. Outbound calls are $0.004/minute. E911 service is 0.49/month. Billing increment: 6 seconds. Those aren't typos.

Getting Started with BulkVS

To get started, click the sign up link on the main BulkVS page . Then fund your account with $25 using PayPal. Or you can sign up for Net 15 billing and pay by check or credit card if you're not in a rush to get started.

BulkVS offers two ways to set up your BulkVS trunking: IP-based authentication and SIP registration. If you don't have a firewall which means you're not using Incredible PBX, the first method is a little safer because nobody can spoof the IP address of your Asterisk® PBX. But it's not for everyone. For example, if you're behind a NAT-based firewall or if your server has a dynamic IP address, then IP-based authentication really isn't an option. Similarly, if you don't have control of the router that your PBX is sitting behind, then IP-based authentication won't work since you have to forward both the SIP port (UDP 5060) and the RTP ports (10000-20000) to your PBX. The beauty of SIP registrations is they work from almost anywhere including double-NAT environments. So today, we'll cover the SIP registration approach which will work for everyone.

There are three setup procedures: one using the BulkVS Control Panel, a second using the Linux CLI, and a third using the FreePBX® GUI included in Incredible PBX®.
