Trying out a low cost router from D-Link
I recently purchased a D-Link DIR-601 Wireless-N 150 Router available at places like Amazon or Walmart for around $26.00. I had heard about an issue with getting IP phones to be able to handle incoming calls, so I put it through a few tests.
When I received the router, the firmware was a little out of date at version 1.01NA. I decided to start my testing at this version and see if I could break it. What I found was that everything worked fine out of the box. Basically the default configuration worked properly in every test I did.
I then started adjusting the different settings that usually break VoIP under the Firewall section.
I enabled SPI - Worked fine
I disabled SIP (under ALG settings) - This finally broke calling.
I finally upgraded the firmware to 1.02NA and re-tested and there was no change to the results. It just worked.
I can't speak for other models of the DIR series, but this one is working as advertised. It is also quite inexpensive. I would not recommend this for a large office but if you are a smaller office then it should work well.
Let me know if you have this router and what your experiences are.
