VOIP Quality suddenly gone downhill

[philwelbourn]

We have a remote office that has for the last year or so enjoyed excellent VOIP calls - both directly into the main office VOIP number and elsewhere too. Suddenly it has become unusable producing what can only be described as sub-par AM radio type audio with very low volume. The other person can hear the converstaion fine - only the remote office has the quality issue - so I suspect its something to do with that VOIP account only or equipment at the those premises.

Any ideas, anyone?

Many thanks

The register issue is fixed now, it was just affecting peple sending/recieving emails to and from BT Hosted domains as when you did a lookup on the domain name for its MX record, nothing came up!

I think this will have to got to BT's advanced diagnostics team to be investiagted why traffic is looping back.

Email some tracert and pathping tests to support@btbroadbandoffice.com, include some account info and the answer to the security question on your account.

Make sure you include the tracert's and pathpings that show 5 hops then jump back to local.

Actually, check your router page or go to www.whatismyip.com as I have just found out that BT are having major issues with people using a dynamic IP address and get a 81.*.*.* one. If you have one of these, try rebotoing your router till you get either a 217 or an 86 address. See if that resolves it.

FYI, this hasnt been fully breifed out yet and isnt 100% confirmed, but lots of people are having the issue and they are trying to find the cause.

Thank you!

I've sent yesterday's test results to that BT address.

We are on a static IP address and it does begin with 81.   From the sound of your last comment, this may be siginificant..?

Googling the specific server addresses where things seem to go wrong brings up what appear to be some regular offenders in terms of slow pings and congestion, dating back as far as last summer.  Aaargh!

Ive had word thast the 81 issue is resolved now... it was only supposed to be affecting people on dymanic addresses, statics are routed/allocated slightly differently.

My problems with packet loss continue, but there is some progress, in that the Support people have agreed there is clearly a problem somewhere in the ukcore network.  A fault case has been raised and we're anxiously awaiting its findings!  (very anxiously, given that it's just coming up for a month since I first started trying to get BT to look at the packet loss issue!)
