Does any one know if there any plans for an advanced VFX/DFX Service with the ability to transfer calls between vfx/dfx lines? effectively removing the need for a pabx. I'm looking for something as an alternative to telecom's centrix service

I don't believe they plan on offering an IP Centrex solution any time soon.

There are providers out there offering hosted PBX / IP Centrex solutions.

Call transfer is a standard VFX feature already. How many DDI's are you talking about?

Chorus has spent $1.4 billion on making their xDSL broadband network faster and even more now as they are upgrading their rural Conklins. If your still stuck on ADSL or VDSL, why not spend $195 on a master filter install to make sure you are getting the most out of your connection?

How do you transfer a call you are currently on?

We would be talking about 4-8 extnsions/ddi's

Couple of ways - assuming VFX with ATA connected to analogue phone:
1. flashhook, then *44, followed by number to transfer to, then hangup
or 2. flashhook, dial number to transfer to, flashhook, hangup

Or if you have IP phone such as SPA942, then there are soft buttons to help.

More than 3-4 lines though, and you are really better with a software PBX such as asterisk, or a VoIP appliance etc. These will all handle call transfer between extensions.

So is it possible to get asterisk to do hook flash on a VFX line? So that you're not using up and incoming/outgoing channel?

(Flash() seems to only be for Zaptel devices?)

Seriously get a VoIP PBX installed, put your client on DVX - even with them running Centrix they will be spending some serious $$ per line. You will save yourself a lot of hassle and grief doing it properly rather than trying to patch something together with string and duct tape.

Cost savings alone should be a big positive, plus a lot more features.

I have to ask the question - what possible use would this be? If you have multiple trunks running off an Asterisk box you don't need to transfer to another trunk, just another extension.

And no, you can't hookflash a SIP trunk only a Zaptel/DAHDI channel.

sbiddle: I have to ask the question - what possible use would this be? If you have multiple trunks running off an Asterisk box you don't need to transfer to another trunk, just another extension.

So I was thinking of something like this: An incoming line would be "transfered" to a mobile phone if the user selected an option. Ideally this wouldn't need to pass through the pabx (asterisk) once transfered. It then means that the line would be available for more calls, and there would be no bandwidth/channel usage on asterisk. The call would then be straight from source to mobile. (With the call charge to us...)

The line is still tied up no matter how you do things.

SIP Reinvite is the form you want to use is very complex and not supported by most VoIP providers and PBX software or hardware.

With the DVX and VFX platforms you have multiple trunks when using Asterisk so it is very much a moot issue.

When I was looking into if that was possible on asterisk the answer came back that no it wasn't, and that there was no way to do a transfer on a sip trunk, like every single ata and softphone ever made is able to do.

I was wanting to use it to only send people to my mobile if they presented caller ID and then chose it in a menu - doing it on an outgoing trunk is crap quality with lag gallore to a mobile and means that its chewing thru my bandwidth.

I am asking because of 2 situations - in one case there is 6 users spread between 2 sites connected by a private high speed data connection. so in that case a voip pabx is a good/viable option

In the other case there would be 6-10 locations requireing 6-12 lines so a voip pabx is not an option

So you mean completely separate locations with each own DSL, and only 1-2 line per location? Or is it 6-12 lines per location (so 50-100+ lines / extn)?
If it is all separate locations with only 1-3 lines at each location, the call transfer over VFX lines (i.e. ATA or IP phones - not soft PBX), will work well. Set them up with speed dials too.

If it's many lines (or extensions) per location, then you are looking at interconnecting Asterisk box, VPN's or a hosted PBX, etc.

Yes completely seperate locations with seperate internet connections and no other connectivity between them

hookflash *44 seems to work ok but it seems to only allow an unmannaged transfer there you cant hold on and talk to the person you are transfering to before putting the call through

Providing they are all good internet connections you could simply run them as remote extensions off the main PBX. Makes life to much easier.
