1) Our phones are running behind a router and we are experiencing reliability and/or call quality issues. How can I fix this?
Sometimes firewalls can interfere with the quality of VoIP communications. Usually it is not necessary to have a firewall enabled on your router so disabling the firewall on the router is a surefire way to fix this.
To accomplish this, you need to login to the router configuration page and disable the firewall from there. The address of this page varies for different routers; it is usually the address of your gateway which is often 192.168.0.1 or 192.168.1.1 but to be sure, you should check the user manual for your router. You can also do a google search which is even easier (Search "
If you do not want to disable the firewall entirely, you need to make sure the following ports are open on your router:
4569 for AIX2
5004 thru 5082 for SIP
10001 thru 20000 for RTP
If you have anything less than PERFECT call quality, 99% of the time blocked ports is the issue. If this does not fix your problem, contact us and we will troubleshoot the issue.

3) How does Fax over VoIP work?
Fax over VoIP can be a tricky thing because of the way the outdated Fax protocol works. If any bit of data is lost in the transfer process, it can stop the fax from coming through successfully. Fortunately, VoiceData24 has the solution for Faxing over VoIP!
We have special software running on our servers that allows Fax to be transmitted over VoIP. You can use a regular fax machine with a Sip ATA or you can use our advanced eFax service--when a fax comes in, it automatically comes into your email inbox and is attached as a PDF file. To send a fax, you can simply login to your VoiceData24 Business VoIP Phone control panel and click the Send Fax tab. Then, browse for the PDF or TIFF file that you would like to send, enter the phone number and click send. It's as simple as that!
Fax is becoming an ancient outdated protocol. Email almost entirely eliminates the need for faxes but many companies still like to have a fax number for several reasons. First, it establishes your businesses and gives it more credibility. Secondly, there is an "urban myth" that there is some type of greater legal binding if you sign a document and fax it versus scanning the signed document and emailing it. In reality, there is absolutely no difference. eFax saves on paper/toner and is a much more convenient way of receiving faxes. With the greater availability of smartphones that can receive emails, eFax essentially lets you receive faxes straight to your cellphone and get them on the go from anywhere!
