I have tried that. My service is Vonage. They placed a "de-bugging device" on my line for 24hrs. Which obviously has not resolved the issue. I am still using the original Linksys router they sent back in 02ish (if I recall). I have never had any issues, until recently. I will invest in a new router for my service, see if that doesn't resolve the issue.
Thank you for your help )
I contacted them again. The tech support rep I spoke to was more fourth-coming with information than the first experience. I was told that I was not the only customer with the issue and that it had been a "glitch" on their end.
I ultimately opted for a number change and thus far has resolved the issue.
