can't open port 5060

[jmsun]

I installed the FPL desktop software and java on a windows 7 home premium laptop. I can received incoming calls but can't make outgoing calls, it keeps saying "no connection to server". I forward port 5060-5061 on my d-link dir-615 router to my laptop. When I checked my ports, 5061 is open but 5060 is not. I can't seem to open port 5060 on my router. When I bypass the router and connect my laptop to the modem, everything works fine. So I know it's the router. Can anybody offer suggestions how I can open port 5060?

((EDIT to top-post myself: Read Dib's first, if your version is compatible, his is the simplest answer.)

A few things to try, section 2 is how I personally would tackle this issue, but that's based on my own personal hardware prejudice, and my penchant as a Network Engineer to demand more out of my routing equipment.:
1) Ensure that your modem is NOT also attempting to act as a router, (Plug into the modem directly, open the start menu and type "CMD", run this program.)
In the black box type "ipconfig".
Scroll up and check the first part of the message to find your IPv4 address, as long as it is NOT one of the following:
IPv4 Address. . . . . . . . . . . : 192.168.x.x
IPv4 Address. . . . . . . . . . . : 172.16-32.x.x
IPv4 Address. . . . . . . . . . . : 10.x.x.x

Then your modem is most likely not acting as a router. (If your modem is acting as a router, contact me back on this thread)
Now that we are assured your modem is NOT acting as a router:
Use a pin to perform a hard reset on your D-Link to it's factory defaults.
Now re-configure your router settings and all port forwarding.

Are you on an ATA or a Softphone? (There are other ports to forward, and they may vary based on your method of using Freephoneline)

for ATA: 5060-5061 OR 6060-6061 still works I believe.
This is only the SIP channel (How your device communicates with the server to find the people you're calling.)

10000-20000 (Or any portion there of) tends to be used for the RTP channel
(This is how your device and the other device actually send voice over the internet)

The softphone is known to use ports in the 13000 range (I don't recall which off hand) to handle registration and call routing.

2) You're in luck,
D-Link has a LONG standing reputation of being back of the pack on router quality.

Fortunately for you, your D-Link has enough guts to install thirdparty firmware.

just type DIR-615 at the top to see your version and read instructions.

Not wishing to interfere with Bloodsongs wise suggestions but....
It seems that this router has the dreaded sip alg

If you have the Revision B firmware sip alg is "on" in the router then, as you have already forwarded ports, follow the instructions in the link.

Ah yes, I haven't run into the Sip ALG issue as frequently as some, thanks dib.
