Hello, 

I have Netgear WNR 2000, cable router  for VOIP. I constantly get cut off, from speech transmission problems. WNR2000 has no ` DISABLE SIP ALG option, that will help me solve any previous problems on earlier routers. 

I need to fix this problem because I'm talking to clients everyday and  I don't want to give them a bad impression. In  the meantime, I am using my landline to communicate with them. This was working perfectly for a year and I can't figure out how to correct this problem. 

Any help will be greatly appreciated.

Thank you so much.

Hey Everyone,

I was wondering if you can help me with a problem. My office is using a PBX phone system from Panasonic and although it's working just fine, my boss thinks that it's not exactly suitable for the office anymore. We're looking for alternatives, for a new PBX system; when one of my colleagues mentioned about IP Phones from Cisco. The problem is, I have never used an IP Phones before. So I kind of lost on the system.
