Check out this great Speedtest – is your Internet connection good enough for #VoIP?

The speed and latency of your Internet connection – important to check in case of problems.

Every now and then customers reports in that all of a sudden the voice quality on their IP phones is not very good anymore while they did not change a thing.

Most likely it is your Internet Speed or some hick-ups on your LAN or router.

Check the excellent speedtest on – you will show a graph like below.

Then. compare that with the actual DSL information from your ISP.

For instance, an AVM Frtitz!Box shows this:

In this example the maximum speed the actual line physically is in line with the speedtest results. There is always some overhead so the actual maximum speed is always lower.

What do to when the results are unsatisfying?
You can several things to improve the quality of your Internet connection so you get better VoIce call quality.

1. upgrade the line speed – talk to your ISP
2. try to get QoS (Quality of Service) enabled on your router / modem to prioritize VoIP traffic
3. analyze what services / servers / PC’s / email systems etc… eating all the bandwidth
(maybe your colleague is watching Youtube videos or big up / downloads are in process)
4. change the router / modem for a faster one
5. do NOT let a Server / PC act as a firewall / router but use dedicated equipment for that
6. avoid double NAT / LAN’s, Wifi interconnects with distortion and bad cabling
7. use the right codec’s in you IP Phones / right packet sizes
8. etc….

Fighting #VoIP #fraud Part 2: false #Ukash transactions with incorrect #SIP prepaid amounts! – do not deliver your services!

Dear customers,


Take a look at the false Ukash transaction below. We receive MANY of these incorrect transactions from a person named ‘Gera Borok’ (registered on our system from Germany) using email address: gbodok1 . Most possibly both name + email address are false. A Google search leads back to some Russian sites.

What they do is this (mail from the Ukash Fraud Prevention Team):

#### Beginning of mail from Ukash ####

Thanks for your email

These type of transactions are indicative of the way criminals try and break the audit trail and are usually associated with money laundering. The criminals would try and redeem transactions for small amounts with a merchant ( usually less than €1) in an attempt to get a change voucher. They believe this action would hide the audit trail so that the new change vouchers is not connected to the original fraud. The minimum spend of € 12.50 which you have in place should protect you from these types of transactions.

Under no circumstances should you accept these redemptions. The accounts into which the small transactions amounts were going to be loaded should be classified as suspicious and should be investigated as well. It is possible that these account holders are connected to a to money laundering scheme. If you have any information on the these account holder, it would be very useful if you can pass this information to our investigators. Information such as verified name and address will be very helpful in preventing this from re-occurring

#### End of mail from Ukash ####

Now here is such a ‘false transaction’: (we do NOT sell SIP amounts of 10 or 50 cents at all!)

è So be careful and always check the Ukash transaction thoroughly before you top up or deliver goods / services to your customers!

If you have more information that you which to share with us, feel free to comment.

Thank you!

Troubleshooting Tip: what do to when your #Asterisk or #3CX PBX #SIP Trunk does not register at the XeloQ SIP servers?


It is always nice to help out a customer quickly on the phone.

There was a problem on a 3CX PBX. It did not register at our servers. The account itself was fine.

We tested it quickly with eyeBeam overhere and on a separate PC at the customer in Malta.
That all worked fine, registered and we could make phone calls.

This directly tells us that the Interconnect to the XeloQ SIP servers is fine as well as the customers’ LAN, DSL / Internet connection and firewall.

So within 10 minutes we determined the issue was in the PC running 3CX. Possibly a reboot solves all.

So remember when there is a problem with your IP PBX, just quickly use the Trunk account in a Softphone to see if the account and the Internet connection to the XeloQ servers are fine.
Then go from there to isolate the problem.

XeloQ fully supports SIP Trunks using the following IP PBX brands:

If you’re still stuck, just give us a call on +31-23-8901271 or send an email to

Have a nice day!

Protect your #Asterisk or other IP #PBX from hacking and fraud. Read our extensive blog now. Let’s fight #VoIP fraud together!

How to protect your Asterisk or other IP PBX from hacking into it, abusing it and spending your credit?

Now XeloQ is growing rapidly, our support team get phone calls and emails regularly from customers on HOW to protect their IP PBX?

This is an important issue and besides normal ICT protection (to protect against Trojans, Spyware, viruses and hacking into mail /webservers) this should be a constant item for each ICT manager to be aware of. It all starts with awareness.

Besides our own security guidelines and blogs we collected some very good information to help you here. If you act on this in the described ways you and your IP PBX are pretty safe.

Ready? Let’s go.

1. Before you start out with VoIP at all, you would like to be informed if the company you do business with isn’t a fraud itself. Check all out here in our own blog:

2. Check our OWN safety guidelines . Read, understand and act on it.

3. Whether you run Asterisk, Trixbox, Elastix, 3CX, Avaya, Cisco, Lync, MyPBX or any other IP PBX, make sure all latest patches are installed. Check this at the supplier websites.

4. NEVER, we repeat NEVER use the default passwords on any system for Administrator access. Restrict REMOTE access to the systems from only 1 IP address

5. If you CAN, always install your IP PBX on a NAT LAN (local area network with NAT / private IP addresses) – this makes it hard to get into the IP PBX from the outside world
Read here to do this with Asterisk: (also LOTS of other good tips)

Summary from that page:

‘Put the Asterisk box behind a NAT router, the system will not be contactable from the outside, but can initiate and maintain registered connections with SIP providers on the outside. That is the simplest way to make your asterisk box secure "enough" whilst still being able to make and recieve calls over the net. It wont work with external handsets, you may need to look at a low latency / SIP/RTP friendly VPN such as Open VPN to give you that functionality’.

6. Don’t use the same username and password on your extensions. Also make sure the internal extensions have difficult to ‘guess’ passwords.

7. Keep the inbound call routing in a different context to your outbound routing. That way, anyone who gets in, can’t get back out again. Common problem and biggest cause / source of toll fraud.

8. Restrict the IP addresses your extensions can register on to the local subnet using permit/deny in your sip.conf

9. Disable channels that you aren’t using (such as skinny and MGCP) and comment out ay default settings in the conf files

10. Set “alwaysauthreject=yes” in your sip configuration file. What this does is prevent Asterisk from telling a sip scanner which are valid extension numbers.

11. If you do not have ‘external’ extensions, you can DISABLE access on port 5060 / 6060 for INCOMING traffic.

12. Use restrictive dial plans (disallow calling to 0900 + Premium numbers) and non-numeric logins for your extensions.

13. If you wonder what happened and / if hackers got in or not, read all in the Asterisk LOG file: /var/log/asterisk/messages

14. Read the comments from Chris on (somewhere in the middle); many of the above info came from him (thanks Chris) and he describes all the .conf files to adjust to make it very secure.

15. Install a SIP port firewall. This will not allow "fast scanning" of port 5060 and will blacklist the endpoint for 1 hour if something like this is happening.
More info:

Now… do NOT want to see this anymore do you? Read on!!


Now all that has been done you want (and need) to test if all is secure. If you think there is no tool available to test and hack into any Asterisk based server, think again. It exists. Dozens of these tools are around but one good one is SIPVICIOUS. It is a SIP SCANNER and checks HOW TO BREAK into your Asterisk box.
If you followed all steps above….and in the article below nobody would ever be able to get in anymore

It doesn’t matter we tell it here because every hacker already knows this tool. So now we are going to USE THAT TOOL to see if you are secure. And that is what we want to know isn’t it?

Check it all on à installation steps and some more things to take care of are all included on that page.

When all is fine, it would be nice to get the following sticker on your Asterisk server wouldn’t it?

Good luck! And if you have any feedback, just post it here. We and all our worldwide IP PBX users would appreciate!

Take care,

XeloQ IQ-Telephony Support Team
