(this is a repost, not sure where the original post went)

Hi all

I've been playing around with VoIP and Asterisk (using FreePBX).

I have a Xnet VFX line as the 'control' separate from any of this (except they all go over the same DSL connection), it goes from line 1 on my PAP2T to my cordless phone. No problems there at all; it hasn't missed a beat.

The * box has been set up to work with two IP phones, one SIP, one IAX, as well as line 2 on my PAP2T, and a softphone on my laptop. No problems there either.

I've set up two trunk lines - one to iTalk and one to Sipserve - here is where interesting things happen.

I've worked through a few issues with Hamish from Sipserve and by and large it's working okay in both directions.

iTalk isn't so good - if I call from my VFX line to my * iTalk number, sometimes it works, sometimes it doesn't. Sometimes my extensions ring for a couple of seconds, then stop, then start again (this happens occasionally but not as much on the Sipserve trunk too). The calling party doesn't hear any ringing tone until the second time (the ring is supplied by iTalk, mine still uses US ones and the calling party hears a NZ one). Sometimes the call simply fails to go through.

If I dial out from * via iTalk, the called party picks up, sometimes all is ok but sometimes but the call won't actually connect for up to seven seconds. (Once it does, latency is about 0.5sec so there definitely isn't some seven second holdup somewhere).

edit: Sometimes also a call coming in through iTalk will die after about five seconds. During those five seconds audio does go two-way so the data is getting through.

These problems are all intermittent.

It's running over a Xnet FS/FS ADSL connection which is about 5Mbps down and 600kbps up. The ADSL router is a Dynalink RRTA1335 which is set up with QoS.

I've heard stuff about problems with iTalk but was wondering what other users' recent experiences with Asterisk and iTalk are?
Because I'm relatively new at VoIP and Asterisk, I'm not quite ready to blame the provider until I better understand what's going on.

Thanks,

Andrew

I've used iTalk as my only phone line since 04 numbers become available around a year ago. I have absolutely no problems at all with the service either incoming or outgoing. I'm currently using the latest TrixBox install (haven't played with TrixBox for quite a while) and running SPA921's, my Nokia E65 and a PAP2 for DECT cordless. Audio quality is rock solid and I've never had any issues with one way audio or calls being dropped.

What voice codec are you using? If you're using G729 remember that Asterisk needs a G729 codec to transcode. If one isn't present it will just dump the call.

Around 6 months ago I moved to VFX for pretty much exactly the reasons you describe.  It sounds like nothing has changed then...

Added to that, the iTalk Forums have been hijacked by a dedicated bunch of forum spammers and very little is done to police them (unlike here).

Finally, the Technical Support from CallPlus (who operate iTalk) is pretty much non-existent...

The above list constitutes plenty of reasons not to bother with iTalk in my view.

It's a real pity because CallPlus were the first local player in this market, establishing free local calling, 5c/minute national calling and more.  Since about a year ago, it seems that CallPlus have stopped any further development work on iTalk and just left it to wither on the vine, not doing anything to fix the problems that many users seem to be experiencing Frown

Wow - two very polarised opinions!

The impression I'm getting here is that iTalk is good so long as you are in Wellington? (I'm not)

edit: No G729 issues. When a call is dropped usually there is a few seconds of working two-way audio beforehand. Anyway I prefer (and have the bandwidth for) u-law/a-law.

That may well be the case.  I'm not in Wellington either and I was trying to use iTalk over wireless, if that's of any relevance to your situation.

All I can say is that VFX works brilliantly and is so reliable, I snipped my landline over a year ago.

iTalk on the other hand...  My wife was ready to throw the phone at the wall on several occasions Embarassed  I rest my case...

I'm keeping my VFX line separate from my Asterisk box for now while I work out what my options are.

I'm looking to eventually have separate incoming home and work numbers, have them both go through Asterisk (and have it treat them differently), but all the options available seem either unreliable or expensive!
I'm not wanting to run any additional boxes here and my home server only has one free PCI slot left so more than one X100P isn't an option (required atm for VFX to Asterisk), hence me looking at SIP trunks for one of my lines.

I'm shopping around for an X100P now, know any good sources? (or alternatives?)

aw: I'm shopping around for an X100P now, know any good sources?

Tony Hughes found one on TradeMe a while back.  Apparently, one of the traders there can order them in at a short leadtime.

Have a look through the Expired Listings and if there aren't any currently listed, go to one of the trader's other auctions and ask them to order an X100P for you.

I'm doing the same as you with separate Home and Work numbers both coming through VFX.  I just have 2 phones on my desk, and have a long range cordless which I can plug in to either one if I'm out somewhere around our farm.

Not very High Tech I know, but it works, and with Caller ID on both phones, I can easily return someone's call if I miss it.  Failing that, both phones also have Answering Machines (one built in, the other provided by VFX).  It works well for me...

I have to agree with you on all of the above.. iTalk don't really deserve any customers and I'd hate to be in a situation where I did require assistance. It isn't really a good look for the CallPlus/Slingshot empire.

I requested a number port 14 business days ago now (From Woosh to iTalk). They said it would take 10-15 days. Tomorrow is day 15 and I have heard nothing from Slingshot or Woosh and my Woosh line is still fully active.

Be interesting to see if this will happen within the given timeframe, or maybe they forgot to do it all togeather

I ported from iTalk to VFX; was booked in a couple of days in advance and then at the agreed date and time it took all of upto 30 mins for the changeover.

Are these numbers you're porting DDI's or real numbers?

I didn't know you could port a single number out of a block?

Any number must be ported by Carriers that are part of LNP , All carriers new and existing must comply to this, Existing Carriers had to comply by 1st April new carriers must comply on acceptance before turning up Local POI's and Local service

Great news! Thanks for that. We've been having problems porting parts of blocks away from an NZ Telco.

Porting is actually working very well , should take about 3 days from Request date, your Carrier should be able to see the status of the port at every point as well.

Cool.

We've applied to become a member of TCF, TUANZ and signup to NADS, thanks for the pointers.

Could you reply to my post regarding people selling New Zealand DDI numbers off E1's to companies outside of New Zealand?

I know of one company that has thousands of them, and another in New Zealand from whom we purchase Wellington numbers (obviously we are based in Dunedin).
