Re: [Asterisk-Users] Re: Terrible inbound call quality vs. outbound
To Bryan, Brian, Daryl, David and others who have reported the same VoicePulse inbound problem I am experiencing: In my extreme efforts to debug this inbound call quality situation, it seems that if I disable the IAX2 registry and instead register a SIP channel against VoicePulse (gw5.voicepulse.com) for my inbound context, the call quality issue is completely fixed. Do any of you guys have a moment to try that out on your configuration? It may help us all in our attempts to pinpoint this issue... even if VP is not willing to put any efforts into diagnosing this.

Re: [Asterisk-Users] Re: Terrible inbound call quality vs. outbound
Rather than changing random * parameters without a clue as to what the root-cause of the problem is, why not fire up ethereal and take a close look at the iax packets? You should see timestamps within the packet that are exactly 20 milliseconds apart. If you see other values, then VP is having some sort of transcoding problem with a machine on their end. Doubtfull it would take long to ID the root cause. Yeah, I've been beating my head against the wall thinking it was something with my config, but alas, it seems to be a case of me needing to RTFF (Read The Effing Forum) and ask the community about their experiences. Sadly, VP seems to have a fairly high comparative rating against other VOIP service while they seem to maintain horrible customer support and crappy line quality. Sigh.

Re: [Asterisk-Users] Re: Terrible inbound call quality vs. outbound
Nugget, thanks for your +1 on this thread. It looks like about five people have all corroborated my findings, which is statistically relevant enough to say VP is very messed up! Doesn't it seem odd that it's only the one half of the conversation duplex? It almost seems like their hardware or the ENcoding half of their codecs are not keeping up with the stream, since they're able to DEcode my voice stream and play it over the PSTN bridge. /rg On Feb 2, 2005, at 8:25 AM, David McNett wrote: On 01-Feb-2005, Robert Goodyear wrote: Sadly, VP seems to have a fairly high comparative rating against other VOIP service while they seem to maintain horrible customer support and crappy line quality.

Re: [Asterisk-Users] Re: Terrible inbound call quality vs. outbound
Try voicepulse in a different area w/ 800 service. With 800 you can jump POPs. If you're stuck with local DID service w/ them, I feel sorry for you. I've seen several recent complaints, and have experienced my own problems, with voicepulse inbound service. They need to upgrade the POP (wherever you are) to add more bandwidth and/or more lines (depending on if you're getting choppy sound, or if you're getting fast busies, etc). Personally, I'm cancelling service in a week or two. Call them and complain, if you think it'll do any good. -m - Yeah, we rocked the vote all right.

Re: [Asterisk-Users] RE: Terrible inbound call quality vs. outbound
Yeah, I figured it'd be pretty pointless from the point I lose control to my ISP, but I figured I'd give 'er a shot anyhow. It really is perplexing me why the inbound calls would be only asymmetrically horrible. /rg On Feb 1, 2005, at 5:04 PM, Gene Willingham wrote: Unfortunately no matter how much Qos tagging you do it will not help the inbound side of your call. Qos is a two way street. Everyone in the path has to support it. If even one router in the path does not support it you can get very poor results. Wouldn't it be funny if Voicepulse was not doing Qos tagging with QOs on their routers? The drops in the incoming calls could be they are not prioritizing voice traffic. The outbound leg is fine because you are. Also, as mentioned before, the quality issues I am experiencing only occur on some DIDs. Specifically 703 numbers are the worst. Last week during the 4 hour outage, 703 (reston Virginia) numbers would not work but 240 (Bethesda Md, across the river) did. Go figure. Try www.txlink.net. They may have a DID in your area. They have a fairly large calling area. They have a different pricing model then Voicepulse, but that may work in your favor.
