OK this is rather strange.
Last night I setup my new Linksys SPA941 and was working perfect.
I tried it today and the call quality is very poor and stuttery, You cant understand who says what. I even tried the talking clock and voicemail with the same problems.
I cant understand how it went from working perfect to really bad over night?
My setup is as follows:
- O2 Wireless Box II Router
- Linksys SPA941 (Plugged directly into Router)
- O2 8mb Connection
I have done a speed test and the results are as follows:
Download Speed: 6912 kbps (864 KB/sec transfer rate)
Upload Speed: 371 kbps (46.4 KB/sec transfer rate)
Latency: 27 ms
I have tried a few things including:
Port Forwarding:
5060-5082 <--- TCP/UDP
8000-20000 <--- TCP/UDP
Disabling Firewall on Router
Totally switched off.
Closing all programs on the computer which use the internet
Outlook, MSN etc.
Is there a problem voipfone's end or do you think its my end? I just don't understand how it was working last night and now its really poor quality.
Can anyone assist?
