MCSNet Phone is only supported to work through the Asus RT-N12 router
Because of increasing issues with newer router models, and lack of community input, the phone service is only supported to work through an Asus RT-N12 running the latest firmware. If you are interested in viewing the old compatibility list, you can view it below, but it will no longer be updated.
Old List: Routers known to work with VoIP:
Make sure your router is using the latest stable firmware from the router manufacturer. Some routers may not work well with VoIP, and you may want to contact your router manufacturer for support on this issue.
The following is a list of routers known to work the MCSNet Phone:
(this list is no guarantee that these models will work, different results may be expected with different firmware revisions and router settings)
Airlink 101 AR504
Apple Airport (but not recommended because they do not ship as routers (think of it like a wireless switch), and have a bug with 169.254.1.X addresses)
Asus RT-N12 (update firmware to latest for best performance) Ver B1 requires firmware 126.96.36.199.32 or above
D-Link DIR-615 Revision C (Revision C requires Firmware Version: 3.12beta1 and up)
D-Link DIR-655 (if issues: disable UPnP through Advanced => Advanced Network)
D-Link DGL-4300 (latest firmware 1.9 required)
D-Link DGL-4500 (latest firmware 1.22 required)
D-Link EBR-2310 (RevB only)
If you have a router that works with MCSNet Phone that is not on this list, please let us know by emailing firstname.lastname@example.org with the model number and any additional steps that may have been required to open up communication.
Routers known not to work or have issues with VoIP:
Belkin routers, but they do work if they can operate with NAT enabled on the radio (SM)
D-Link DIR-601 Revision A
D-Link DIR-615 Revision E
D-Link EBR-2310 Revision A
D-Link WBR-1310, WBR-2310
Linksys WRT 120N
Linksys WRT54G, WRT54G2v1, WRT54GX, WRT54GL, WRT54GS (unless using custom firmware (ie. DD-WRT))
Netgear routers ALL (many reported sporadic issues with VoIP)
Many routers will work without requiring any additional configuration in the router. If you find that your phone adapter is not able to communicate through your router, then the router is likely incompatible with VoIP, but you can try opening the ports on the router. There are 2 ways to open access through your router:
1) Set your phone adapter to communicate through the DMZ of your router
The De-Militarized Zone of your router will allow all traffic directed at your phone adapter through.
2) Open the specific ports for incoming traffic directed to the phone adapter (port forwarding)
Use port forwarding to open only the necessary ports to the phone adapter
Log into your router.
Set a static DHCP (DHCP reservation) to marry your phone adapter to a specific IP address (save)
Enable DMZ, and set it to the IP address for the phone adapter. (save and reboot)
Reboot phone adapter
Log into your router
Set a static DCHP (DHCP reservation) to marry your phone adapter to a specific IP address (save)
Set up port forwarding on your router. You must specify that ports 5060-5061 (UDP), 53-53 (UDP),
69-69 (UDP), and 10000-20000 (UDP) are forwarded to the IP address of the Phone Adapter.
