Router Policy


Blue Ocean Technologies is a provider of Hosted VoIP service that is intended for use over Broadband Internet connections, such as those provided by AT&T, ComCast, Cox, Charter Business and others.  These providers provide general access through the Internet through a modem that they supply directly to the end-customer.  This modem is generally acceptable for home use, but it is not considered a business-class device and it is not considered to be an acceptable solution for Hosted VoIP connections such as those provide by Bluewave.  Consequently, it is our position that the customer will be required to provide their own routing solution in order to use the service provided by Bluewave Hosted Services.   Bluewave Hosted Service does not provide routing equipment for the end-user to connect to their broadband connection.  In order to successfully use the Bluewave Hosted Service we provide, the customer must be aware of the following requirements:

1.       Broadband cable Internet, AT&T UVerse, Verizon FIOS or any other service provided to the customer by their respective Internet Service Provider (ISP) to enable Hosted VoIP requires the provisioning of one or more static public IP addresses.  The ordering of the public IP address or addresses is the sole responsibility of the customer of the customer’s Information Technology (IT) specialist.

2.       Once one or more public IP addresses are provisioned by the customer’s ISP, the IT specialist selected by the customer for this task is required to work with the ISP to change the onsite modem from a gateway mode to a bridged mode of operation.  Bridging the ISP modem removes all services from the modem, such as: Network Address Translation (NAT), DHCP, Firewall, Stateful Packet Inspection (SPI) and any other service previously provisioned on the modem.

3.       The IT Specialist will recommend a suitable router/firewall, based on the following parameters:

a.        Wireless Service

b.       Session Initiation Protocol (SIP ALG disabled) compatibility

c.        DHCP

d.       Network Address Translation

e.       User support for all connected devices

f.         Sufficient throughput for bandwidth management and voice quality of service (QOS)

4.       Once this device is installed, it will be the responsibility of the customer, his service provider and the manufacturer of the firewall to maintain, trouble shoot and monitor the firewall.  Bluewave Hosted Service assumes no liability, either express or implied, for the operation or the maintenance of the firewall, the ISP modem or the circuit provided by the ISP.

5.   Blue Ocean Technologies does not recommend nor endorse the direct connection of our service to a Cable Modem. Blue Ocean Technologies will not accept responsibility for nor support these modems or problems that arise from their use. These problems manifest in one way audio, echo, and dropped calls. Blue Ocean Technologies service department will refer Customer back to their ISP if it is determined that a Cable Modem is being used instead of a proper business grade Router/Firewall.

Hosted Voice is an application that rides on your Internet connection or your internal data network, much like email and video.  As with those applications, the quality of your telephone experience is directly related to the quality of your internal data connection.  Normally, with a high-quality broadband connection and the right firewall, you can expect very high quality voice service.  Unfortunately, voice service is dependent on many factors and it is classified as a “best-effort” service.  Selecting the right ISP, IT Specialist and router/firewall combination will minimize most problems you will experience with voice quality.

Blue Ocean Technologies maintains a list of compatible routers that we will share with your IT Specialist, including tips and suggestions for provisioning these devices.



We offer a few firewalls that offer a high quality VoIP experience. If you would like to purchase this device, please contact our sales department at 205 776 6910 or by email at 



Blue Ocean does not recommend, sell, price, or offer any advice on which router/firewall is best for your business other than the SimpleWan. Please consult a qualified IT professional to advise you in this area. Should you decline to use our recommended router/firewall, all of these are known to work at the time of publication.

Sonicwall-TZ215 or higher
Fortigate-Fortinet 100 or higher
CheckPoint-Model 600 or higher
Cisco-ASA 5505 or higher
WatchGuard-M200 or higher Firebor or XTM
Untangle-U50 or higher; M1500 or higher
Sophos XG Series-XG85 or higher


We do not recommend Netgear, DLink, Linksys, and other consumer grade equipment under any circumstances. 

Use of a device not on this list invalidates any performance guarantees by Blue Ocean for quality of service.

You will need the services of a trained IT professional to install your router/firewall. The maintenance, care, and programming of the firewall device will be the responsibility of the customer and his or her IT Staff. Blue Ocean under no circumstances will troubleshoot, program, log in to, offer advice, or support any customer supplied equipment.


Recommended Network Configurations


The following are VoIP router/firewall settings that will help provide better call quality for your phone system. While it is not possible to cover every single model and type of router/firewall on the market, these general guidelines will apply to most, if not all, of those that are available to you. Call quality is mostly affected by the local area network (LAN) you have in place, so it is always a good idea to have a skilled IT professional on hand to assist with issues that are internal to your network . This includes routers, modems, switches, cabling, servers, Internet Provider, wireless access points, etc... 

UDP Timeout - 300ms

QOS- The following ports should be open and given highest priority:

·        SIP (Session Initiation Protocol) UDP - 5060-5081, 4000-4999

·        SIP (Session Initiation Protocol) TCP - 10001, 5060-5069 (Communicator)

·        RTP (Real-Time Transport Protocol) 10000-20000

·        PWProxy (Communicator) TCP 10005

·        Jabber (Communicator) TCP 5222-5223

Disable the following:

·        SIP ALG

·        Stateful Packet Inspection - SPI

·        UDP Flood Blocking

Physical ports that have priority settings should be given highest echelon to the VoIP devices attached to them.


The following are other factors that will help:


Making sure the modem is compatible and in bridge mode, if needed. ( This could also be referred to as pass-through mode, route only mode etc. Each ISP is different).

Static Public IPs assigned to the router. (Assigning to individual phones work as well)

CAT 5 Cabling or better

Separating the data & voice networks. 

Increasing your current internet speeds. In particular, your upload speeds. This is especially important if you are constantly streaming videos, instant messaging, monitoring, backs-ups etc.
