We have very high taxes on hardware imports in Brazil, so software is
not a problem on the equation. Cisco's routers for example are 3 times
more expensive here then in the US (even the cheap ones). If the price
of the equipment is compared to the price of the G729 license, the
latter becomes quite insignificant. And bw has poor quality and high
prices.
The same rule applies to all Latin America.
Hope I have illustrated the picture correctly.

being

had we carried on using G.729, we'd have lost about 30% of our
margin on
that route.

Hi Michael,
I'm not sure about this, when we need to use G729 on asterisk for example, we pay the digium (U$ 10/channel) licenses.
U$ 1.00 dolar = R$ 2.31 (Brazilian Real - local currency).

What relevance does that have to the current discussion?
Brazil is a country with large trade barriers, which skews the cost of
hardware from the world market considerably. It is also pretty advanced,
technically, and has a local base of electronics manufacturers. That
considerably affects the economic tradeoffs in the use computers,
telecoms, and other technology in Brazil. If something can be
manufactured (or at least pass through final assembly) in Brazil, it
will generally be much cheaper than something imported. That means some
people find the use of locally made intelligent E1 cards is cheaper than
the use of dumb cards from Digium or Sangoma.

Steve

It surprises me someone doesn't assemble Tormenta 2 cards in Brazil.
Various people have done this in China, and shipped a lot of cards. They
have to be a lot cheaper than the Khomp and Digivoice boards. The key
issue with the Tormenta 2 is the lack of on board echo cancellation.
Although OSLEC performs well, 120 channels of EC is a lot to do on the
host CPU. Still, a lot of cards ship without on board EC.

Steve

Hi João,
Please say hello to Giancarlo at Khomp for me :)
Khomp is the best example in Brazil of what good engineering and fair
commercial prices can do to a country that suffers from high import
taxes. Unfortunately some companies are still inclined to buy imported
products/brands instead of favouring local production. Apart from this
discriminatory issue, I believe that local research and production can
turn the table of trade barriers imposed to development countries.
By the way, are you aware of any companies producing SIP phones in
Brazil ?

Raul Fragoso

Hi Steve,
My point is more towards the high import taxes here. A foreign company
won't pay as much taxes to export to Brazil as brazilians would pay
import taxes for such goods.
I will give you a simple example: a Snom 320 phone would cost roughly US
$180.00 if bought in the US. Here it would cost at least double the
price, but usually more. We pay almost 100% for importing taxes + GST,
excluding the greedy profit that dealers and resellers usually apply,
but Snom (or their distributors) would pay only a small fraction of that
to export phones to Brazil. The irony is that we don't see where all
this money is spent, as the country still suffers of a huge social and
economical dissimilarity among their people.
On the other hand, our current government seems to be making some
progress to make exporting from Brazil easier, specially for small
companies (international trade is known to be very bureaucratic here).
Anyway, this is turning into a politics discussion thread and I know it
can annoy some people. Just to stay in the subject thread, I also
endorse the support for open codecs rather than paying millions for
G.729 licenses.
Regards,
Raul Fragoso

If you want Speex support you need to target the chipset manufacturers:
Here is the Texas Insturments chipset that Polycom uses in the IP650
Quote: |
CPU is TNETV1050/C55x, rev 2 running at 162MHz with memory at 125MHz.And here are the codecs that Chip supports from TI's datasheet on this chip:http://focus.ti.com/pdfs/bcg/tnetv1050_prod_bulletin.pdf
Codec Options*
G.711 Codec, G.726, G.729AB, G.723.1A, G.722 wideband codec | Speex is not listed, so Polycom can't do Speex.
I should note that even the non-HD Polycom phones have this same chip and are capable of doing G.722 some some config tweaking.
I'm willing to bet that Cisco doesn't make their own DSP chips either. Find out who makes their chips and put pressure on that chip manufacturer to develop chips with Speex support.

Are you saying that you have actually gotten the non-HD versions to do
g.722? Or are you saying that one might be able to do this? If the
former, can you share what you did?
