I just recently switched from a Motorola modem (which the cable tech took) to a ubee router/modem combo. I work from home so I have a phone that uses VoIP and now it no longer works. I tried to run a test through my company's site and I got a message stating:

Your computer couldn't call our location on the standard SIP port (5060). Generally, one of the following environmental issues causes this failure:

If you have a VoIP Service, your VoIP/Phone Adaptor may have reserved the standard SIP port and is filtering out our SIP packets. Consider temporarily removing the Adaptor from your configuration and re-running the test.
Your Personal Firewall, if you are using Windows XP, may be filtering the SIP and UDP ports used for communication.
Either your home firewall or your broadband provider's firewall may be blocking the SIP and UDP ports used for communication.
Please check these firewall settings and ensure that UDP ports 5060 and 50000 - 50100 are open for RTP streams and SIP signaling. Then re-run your test.

How can I open the ports?

Are you saying...that a tech came in and switched equipment...and did not test the connection before leaving?

Were the drivers from the old modem uninstalled, using Device Manager?

I wasn't asking the tech what he was doing every step of the way nor did he tell me. I was not aware that switching a modem would have an affect on VoIP. At this point, I want to know how to fix it.
