hkbn garbled voice Post Reply with Quote Edit/Delete Post Report Post to a Moderator       IP Information Go to the top of this page

Hi,
I've just started having a problem with both my hkbn trunks where the voices are garbled. Other trunks seem OK. Is there any way to debug what is going wrong with these trunks? The trunks are located in Hong Kong which is low latency to the www6 server (whereas a trunk that is working is in the UK).

Thanks

Mike

Well, to ensure it's not a server or network segment related, you can try moving your account to the San Diego server which seems to be only 30 ms further away from Hong Kong, with fewer hops up to the point we are allowed to observe.

Thanks Diafora,
For now the quality seems better so I will try moving servers if/when it happens again.

FYI that first traceroute seems overly long - I am based in HK and have 18ms latency to hkbn and 65ms latency to www6 so 150ms from www6 to hkbn looks like double what it should be (traceroutes below). Perhaps there was a temporary problem with the routing between www6 and hkbn?

Well, Time of Day traffic patterns differ, but the discrepancy seems rather large. I am glad it works for you now though.

Unfortunately the problem is back and switching to the san diego server didn't help. I still get ~65 ms from my home to www6 and ~17ms from my home to hkbn. (Although the extra latency isn't likely to be the sole problem Is there any prospect of having your datacentre in Japan investigate whether they have a routing problem?)

Interestingly, I have two HKBN numbers - one on this account and one on my pro account and the garbling seems much worse on the pro account. Is there any reason why that might be the case?

Actually, there is one possible reason - the pro account just forwards calls to this account - perhaps there is a problem in the routing between the two accounts?

Cheers

Mike

Hi Mconvey,

Are you still having this problem? Also, do your calls get disconnected after approx. 7-10 minutes?

Thanks.
