Re: VOIP breaking up

Hi Dazzled

I have now downloaded Ekiga - this looks like a simple softphone - and as you suggest the jitter is adjustable in the Audio Codec.

Thanks for you help

Re: VOIP breaking up

Thanks Dazzled

Another quick question if I may.

Thanks

Re: VOIP breaking up

Let me know if this is not the case - I have already enabled QoS for UDP packets - but this only affects outgoing traf...

Re: VOIP breaking up

This really is starting to look like a jitter problem - more than a network speed problem per se. I have just run a network packet capture test on a VoIP session with the following results Source IP Drop by Jitter Buffer Out of Sequence Wrong Time Stamp 192.168.1.3 (me) 0.0% 0.0% 0.0% 58.96.1.2 (Exe...

Re: VOIP breaking up

I have been having exactly the same problem with Exetel VoIP since early this year - prior to that it worked fine. I’m on an 8Mbps plan and during the day I get about 3 – 6 Mbps and generally VoIP works fine. During the evenings my speed regularly drops to sub 1 Mbps – often lower, perhaps down to 0...
