Clearfly is pleased to announce a service change aimed at making the installation and configuration of registered SIP trunks faster and easier for our customers and partners. These changes effectively eliminate the requirement that Clearfly customers with registered SIP trunks add a P-Asserted-Identity (PAI) header to their SIP signaling when sending a calling number that they don’t own. This header was necessary so that our switch could properly associate the call with the customer’s trunk. Now, however, Clearfly will strip any PAI that the customer sends to us and will assert our own PAI header based upon the source IP address of the customer’s signaling.
In addition to simplifying the configuration for existing registered SIP trunking customers, this change will open up a new world of possibilities for customers with existing static SIP trunks, many of whom have been prevented from utilizing registered SIP trunks due to an inability to properly insert PAI headers into their signaling — an especially common problem for those wishing to forward or transfer calls from their system while preserving the original calling number. Registered trunks will eliminate the requirement for these customers to maintain a static IP address, and all registered trunk customers will be able to send any valid calling number they’d like with no additional configuration requirements.
This new feature is now the default for all new and existing registered SIP trunks. Some customers with uncommon configuration requirements, such as those with multiple SIP trunks from the same phone system, will still be required to insert a PAI header into their signaling. For these special cases, Clearfly has enabled the ability for customers to change their realm configuration in real-time via the Clearfly Portal. See Clearfly’s FAQ for more details.

Clearfly is pleased to announce that customers now have more control over which international calling destinations they want to allow calling to. This feature was implemented to augment our International Fraud Mitigation program and will help to reduce the financial exposure of customers as a result of international call fraud. The idea is to limit the customer’s ability to place calls to common call fraud targets, thus making then less attractive targets for would-be abusers.
International destinations now have a Tier level of 0, 1 or 2 assigned to them, based upon the frequency the number is legitimately dialed and the cost-per-minute of the call. Customers and partners can view the tier that has been assigned to each international destination here.
All new and existing customers have been configured to allow only calls to the lowest tier (Tier 0) destinations. This tier covers 85% of all International destinations while blocking destinations that may the customer’s system an attractive target for international call fraud.
If you’d like more information regarding Clearfly’s new International Calling Tiers, an in-depth discussion about this new feature is available in our Knowledge Base.

Clearfly is pleased to announce that customers can now pay their bills online, saving them time and money (stamps aren’t free).
Customers can now follow a unique link which is included their invoice email which takes them to a secure page where they can pay their current balance (or any amount) via electronic check (ACH) or credit card, depending on the size of their account.
Online payments are a time savings for both Clearfly and the customer plus allowing more accurate and timely application of payments to the customer’s account. It really is a win-win for everyone involved.
This new option augments our existing automatic bill payment system which can automatically debit your checking or credit card monthly. Some customers understandably want to have a bit more control over the date which their payment is sent, so this new payment page provides them that option.
Please email firstname.lastname@example.org if you have any questions on how to get started.

Unlike a traditional phone system, a Voice over Internet Protocol (VoIP) enabled system may be accessible over the Internet. While this facilitates access to many new and exciting features such as trunking and access for remote users, an Internet presence also makes systems potentially vulnerable to those who wish to hijack your system in order to make expensive phone calls to far-flung locales.
Keeping these would-be freeloaders from using your phone system for no good is as easy as following a couple simple rules:
If your system doesn’t need to be accessed by remote workers then don’t allow access to the entire Internet. Have your firewall provider add rules which only allow access from your sip trunking provider(s).
Use very strong randomly generated passwords. While you usually only have to enter a password every once in a while, those who are wanting to use your system without permission can try thousands of passwords a minute. This isn’t their first rodeo so they don’t just guess; passwords like admin!23 are on the top of their list to try.
If your voicemail system permits remotely changing a call forward, ensure that it does not permit the forwarding of calls to international numbers.
Even if you are following these guidelines religiously there are bound to be systems that slip through the configuration
cracks, or someone down the line will tire of entering their complicated password and change it to something like
When this eventuality occurs the cost can be extremely high. At Clearfly we have seen compromised customer phone systems with only a
few lines tally up over $2000.00 per hour in international calls. Imagine now that they gain access to your system at 9 PM on a
Friday and you don’t notice until all your lines are in use Monday morning. There could be close to 60 hours of abuse before
anyone notices what is going on. Even at $100 per hour that is $6000 that you will be responsible for. As a fail-safe you
should seriously consider choosing a SIP trunking provider which provides
near real-time fraud detection, and can block your international calling when the activity is deemed suspicious.
