Problem with VoIP connection

[draftvader]

I am using a VoIP service based in the UK and, for the past 2 months, it has been brilliant.  Last week I suddenly started to get a lot of problems with my outbound call quality so I started troubleshooting with my supplier.  We found that the routing via Singapore was dropping packets.  I have been monitoring this routing over the week-end and it is still doing this.

When the UK wakes up I will be working with my supplier again.  My thoughts are towards trying to find a SIP proxy to get round this routing issue.  I just wondered if the clever folk on TV (being serious) had any better suggestions (VPN, etc) or have had a similar problem and worked out a solution.

 

I'm using Zoiper and/or Xlite

Mine has been the same to the U.S. and Canada.

has gotten better in the last few days.

Agian Sun Spots are causing havoc with communications all over the world.

 

Check out the Sunspot web site when you have problems most likely lots of activity when you are having problems. Same with the net.

Perhaps invest in an UK VPS at digital ocean for VPN purposes.

L2tp works pretty good with VOIP.

 

5$ / month.

True has direct UK connection. TOT also has direct UK connection.

Probably a bit techy, but i found IAX to be a far superior protocol than Sip &RTP. There are a few IAX compatible clients out there (and of course, if your number provider supports it. Or you could run an asterisk instance (maybe trixbox in a VM or small PC)....Having your own PBX will also allow you to use it's jitter buffer to get over outbound loss/latency.

 

(I worked for a commercial VoIP/Sip provider for a few years, so dealt with this a lot).

Thank you to all.  Brilliant stuff.  In the end my issue appears to have been a dying modem.  I spent 30 minutes working with my provider's support team and we just saw too many random inconsistencies in my traces so I took my modem to 3BB, got it swapped and "bingo" sorted.

Nonetheless I'm going to absorb all your suggestions if just to improve it further.  Had a great afternoon on the phone :)
