[Blink] Audio Delay

The problem comes and goes, sometimes it works for a whole day so these kind of tests aren't possible.
Telephone never has a delay - there is a problem with the new macbook air, using OSX 10.7.1, with bluetooth enabled. 
it causes some kind of invisible packet loss.
I did keep saying I thought it was OS related, but telephone for mac, never has a delay, it has clear calls with some choppiness on occasion.
I'm a business man, I don't have time to f around with this stuff I paid silly money for this Mac because I really believed Mac stuff just works out of the box.
So going for a pair of headphones and another SIP client isn't what I wanted but I need to leave the UK with a working setup in a few weeks and I'm not 18 years old and curious - i have better things to do than argue with you about whether 0.2% packet loss is acceptable or not.
GSM codec should work on a connection thats unusable for web pages, its very low bandwidth.
Anyway, I have the answer - the MAC has a problem with its wireless stuff (great, the most expensive turd I ever bought) and Blink deals with that by placing a huge delay on the calls - which other clients do not.
Anyway, this is all irrelevant because I imagined the call centre I setup in 2006 and the problem is actually my asterisk box, right?

You could have narrowed it down faster if you downloaded Blink on Windows and made a call between the two instances on Mac and Windows without any server in between using Bonjour. Then you had eliminated any intermediary and knew for sure where the delay is.

- It seems to me there is the possibility that the new Macbook Air has issues with the wireless adapter if bluetooth is enabled.
Some kind of interference
If you look back on the history of my emails you'll see I hinted at some kind of jitter or noise problem as speed tests showed good speeds but the connectivity was total shit.

Nick,

You might have overcome your immediate problem, but you've passed up a significant opportunity. It sounds like you've learned nothing from this process.

Blink works fine on the Mac. Blink is use daily by thousands of people who don't report the trouble you've experienced. Unlike most SIP clients, Blink has the Mac as a significant focus, releasing on Windows later on.

There was something wrong with your installation. Think about the whole signal chain. Where could seconds of delay occur? Where does the RTP stream get buffered? That's a huge amount of delay!

Getting something to work is nice, even useful. Knowing why it works (or doesn't) is incredibly valuable.

Hi

We already have a call centre setup since 2008 in a datacentre using an Astersik install and of course as I keep saying lots of windows clients using the box fine on very bad connections like USB sticks.

I found something called Jitsi; and with some help from somebody here called H (thank u) we've got a zero delay !

Yay!

Nick,


You need to approach your troubleshooting in a different way. You have indeed narrowed down to an issue with YOUR Blink install, but that doesn't mean it isn't a network issue or an asterisk issue that only manifests itself in the one software/equipment string. With so many using Blink without an issue, you do understand that it could be anything from other software you have running on your Mac to a setup issue either on the Blink or Asterisk side settings (extension or otherwise) for that particular device? It seems you just keep throwing out the "1500 pound paperweight" emotional comment, as if that is supposed to help narrow down an issue. 


If you are setting up a call center, I would suggest you rethink your strategy. I think you'll be far better off with a commercial solution with professional technical support rather than a piece-meal do-it-yourself (without the expertise to manage and maintain) attempt.

Do you know how frustrating this is??!

Please tell me why you think the problem is the asterisk box when i've got a PC here that makes crystal clear calls all day long using the same server and login info on the same broadband link as this Mac that has the delay.

Someone with enough technical knowledge in Asterisk located on your premisses is likely the only person who can help.

That's what you keep saying. 

That's what Apple say.


Why do the PCs work fine?


It just can't be a network issue can it? Can you tell me how it can when we've run this business 3 years with PCs which are still working fine and I can't get this s/w to work in 3 locations now - delay delay delay.


It just isn't the connection or the server, if it was the rest of my staff would have the same problems, suzanne my sales manager is happily chatting away all day long today fine. It's only me with the delay.


I can't see how you can blame anything other than the MAC and / or it's SW


I really need some proper help, if I can't get it I have to sell this and buy a Sony VAIO or something I don't want to do that, I want to keep this, but I can't work on it...


Is there anything else you can do to help? Sensible answer only please

You are blaming Apple, Blink/Telephone but based on my experience you are on the wrong track.


You need someone technical with experience in IP networks and/or Asterisk to find the cause for your problem at your location.



This mailing list will most likely not be able to help you as the problem has to do with your local network Asterisk setup rather than your computer.

Hi everyone 

I'm at a 3rd location today, central to a large town, it's one of our offices.


I have 2 people here working fine on SIP phones using Windows and Qutecom, today Im trying the macbook air / lion 10.1.7 again and the same problem, delay of about 3 seconds making the calls almost impossible


As this is the 3rd location I've tried, and telephone also doesn't work (no delay but choppy), it has to be a problem either with the soft phones or the OS. Apple are blaming the soft phones of course. 


Speedtest here shows 11meg down and 1 meg up, jitter test shows grade B line, excellent.


Here is the trace again for the last call, 3 sec delay. 


Once again my acer laptop works fine here, it's just the mac. Desperate for a fix as I travel in 4 weeks and this mac and blink will be going in the bin and i'll be writing off 1500 pounds :( don't want to do that can anyone help me?


(help me without blaming my connection, this is the 3rd location, the acer windows 7 machine works fine again here)
