Hi,

Just wondering if WXC VFX supports the G.726 (32k) codec?

Cheers

No sorry not at this stage, possibly at a latter date but there is really the requirement for it as the G729 and G711 cover most apps

Hi,

The reason I asked is because most hardware phones support G.726, which means asterisk doesn’t have to trasncode if you want to use G.726 on your sip trunk. It also fits nicely in-between G.711 and G.729 in terms of bandwidth and call quality.

All this is elementary anyway as your sales team wont provision more than 1 VFX Asterisk line on DSL anyway. (Though 2talk looks quite promising).

2 Lines actually on Asterisk as this fits the residential rules

CRKD: And for business VFX users?

It all depends what you are trying to do.

You can have 2 VFX accounts configured per address and there is nothing to stop you running multiple VFX trunks over the same internet connection. More than this and you'll have to pay business rates which is logical considering most households don't need more than 2 phone numbers!

An Asterisk account also allows up to 2 incoming and 2 outgoing calls per VFX connection vs a single call that a regular VFX account gives you.

The problem is their whole attitude of "we don’t like DSL".

They won’t provision more than 2 VFX lines (or DVX) over DSL; they will only provision it over say Araneo Wireless, UNS, Vector Fibre etc.

By the time you combine the extortionate access costs of one of the above, it puts the pricing up to a level where you ask yourself why I am bothering with VoIP? It’s just as cheap to use ISDN / PSTN!

It's not that we don't like DSL we don't think think that it is a business grade service, we find everyone will like the price point of DSL but Residential customers will be a little bit more forgiving than a business, they are happy to take the price breaks but when the DSL goes down then they will very quick to want it fixed then and then, and as we know DSL is not a business grade product.

With the current state of ADSL in New Zealand this is probably a very wise protection mechanism to stop their product's reputation being harmed by people who have no real idea about VoIP and think they can run a call center over a $49 per month internet connection!

People just seem to associate VoIP with being a way to save money with their calls which isn't the best approach to take. Switching to VoIP is also about offering features that simply can't be delivered over regular PSTN connections.

We had a customer this week that has a mixture of ISDN and WxC VoIP, Adding DDI's to their ISDN circut dropped it. Telecom have told us that the ISDN trunk number is not a valid NZ number, so their ISDN has been down for a week and Telecom don't know how to fix it.

Not to mention that Telecom applied a Onehunga Number to Papatoetoe Exchange when the client is in East Tamaki.

Thanks God for VoIP as the customer hasn't even noticed except that they can't make as many concurrent calls.

Hmmmm

DSL contracts tend to be "best efforts" and are not intended to provide guarantees for mission criticial services like VoIP.

WxC tend to go for the "offer what we know we can provide reliably end to end" approach, where as 2talk and various others go for the "we'll offer everything our gear supports, but good-luck-have-fun if you rely on something that we dont guarantee in the contract" approach.

Its just a matter of what kind of downtime you are prepared to accept and what kind of quality you are after. If you get a bunch of lines from 2talk and then your DSL line goes down for a week then you will get no sympathy. Get an enterprise grade connection through Areano, Vector, FX, Citylink et al and they will be quicksmart in getting you back up and running in the unlikely event of a failure. Their networks are intended to be highly reliable and charge you more in return for a guarantee over the uptime and service level.

If you really need a number of lines then you are probably best to go for a mixed approach with ISDN and VoIP lines over DSL just as cisconz pointed out. Therefore you can access all the smart features available through VoIP as well as having the peice of mind of an alternative line for redunancy.
