G.722 problems with IAX
Hello,
I try to move our asterisk installation (3 Asterisk servers in different
offices connected using IAX and a lot of SIP phones, as well as ISDN
connections using CAPI) to use G.722 instead of G.711.
Asterisk 1.4.25.1 is used with the G.722 patch (the fixed one, which solves
the gain problem).
So SIP-to-SIP and to ISDN there is no problem. G.722 itself works and
transconding to G.711 for

ISDN 4 BRI card for UK
Hello
I want to setup an Asterisk in several offices with 4 BRI ISDN. I am looking for recommendations on hardware. Criteria would be ease of setup, reliability and cost.
The Eicon 4 BRI cards seem fairly pricey. Shame Digium don't do a ISDN BRI card.

Testing ISDN T1/E1 Bri and Pri etc.
Hi All,
Can anyone recommend any test kit that you can hook up your Pri/Bri
cards to without having actual ISDN in your office. For example
testing an * system before it goes to a clients office.
Thanks,
Gavin.

G.722 between Eyebeam and a Polycom IP650
Hi All,
So I've been exploring the use of G.722 encoded wideband audio
recently. I have three different SIP devices that allow this: Eyebeam,
IP650 and a Siemens S865IP. The Siemens and IP650 seems to work fine
together. Calls pass between them in what the Polycom notes as "HD"
mode and the audio quality is certainly very good.
However, things are not so easy with Eyebeam and the

best ISDN BRI solution for DID
I want to test asterisk with its DID functions on a smaller scale without the expense of a PRI. I am in the US, and want the most reliable/stable, and feature rich solution that I can have.
What ISDN card would be reccommended?
My clec switch operator says he can/will send DID info to my BRI's if I wish. Can Asterisk, or one of its addons support this?

chan_capi-cm, Euro ISDN bus: 2 extensions on same BRI port not working
Hello,
I am using a system with an AVM ISDN PCI card (fcpci) and asterisk with
chan_capi-cm-0.6. The hardware is connected to a Siemens Hipath 3550 PBX. As
a BRI connection has 2 channels and allows 2 simultaneous calls,
numbers/MSNs 6391 and 6392 were for provisioned for each channel. The system
is working (partly, read on), the trick is the correct cable wiring and
setup the PBX's port

Are the Siren7 and Siren14 the G.722 HD voice codecs?
Hi Everyone,
1- Are the Siren7 and Siren14 the G.722 HD voice codecs?
2- Are these codecs only for Polycom units or are they universal across all
other SIP phones that advertise the HD voice codec like Aastra?
3- What is the main difference between the two and is it advisable to run
these over the INTERnet (not INTRAnet)?
Thanks

ISDN, BRI, PRI, voice over IP, and more...
Hi,
I am thinking of starting a project at Work to pilot to use of Astrisk
and VOIP, and would like to tie in several projects together.
Currently we are looking at purchasing an ISDN and H.323 based video
conferencing system from Polycom. It suggests the use of 3-4 BRI lines
(ie 6-8 B channels, but in the form of individual BRIs). We need ISDN

Eicon equipment, BRI Server or PRI?
Hello Everyone,
I am once again wondering about EICON. I have had no success with the
Diva Pro or Diva Pro PCI, so my question is, does anyone use an Eicon
Server BRI card on Asterisk? Or would I be better off trying to get a
split PRI?

About BRI / ISDN hardware. What to buy?
Hello everyone.
I need a BRI ISDN card that works in Romania. I already have one of the
"Cologne HFC-S" PCI cards and it doesn't work right, it's junk. I get
waaaay too much echo using it. I'm now "shopping" for a better card. Can
anyone recommend me a card that "fits" the following:

(b) Has one or (preferably) two

Where to purchase ISDN (BRI) cards in Australia (preferably)
Hello all,
I was wondering if anybody knows where one might obtain a PCI ISDN
card supporting a single BRI for use with Asterisk in Australia (and
using something like chan_capi).
Because of the Isdn4Linux DTMF issue, I don't want one of those cards.
I've already spent too much time messing about with my current card.
I'm after something like the AVM Fritz! cards. I found one place

2 x Eicon BRI ISDN devices (UK)
Hi
I have installed 2 x Eicon BRI ISDN cards into a Suse 9.2 server. We can
use all 4 lines for out going calls fine, but on incoming we can only use 2.
On calling in using the main msn, the 3rd line gives a an engaged signal.
I have unplugged 1 of the cards, and the other card takes the 2 calls. I
then swapped this around, and this also works fine. But when using both
cards, we can only use

ISDN BRI hardware
Hi,
Anybody have lots of experience with PCI ISDN cards and Asterisk? I'm
thinking of getting a BRI in my house to deliver more advanced signaling to
my PBX (yes, I'm a geek :-)) but I've never played with isdn4linux.
Is there any particular BRI card that works better with Asterisk than any
other?
Also, can the BRI interface cards participate in conference, etc., since

NEWBIE - No Audio on ISDN BRI (Teles PCI)
Hello, folks! This is my first post here.
I installed Asterisk from scratch and after reading a lot of information on
voip-info and this mailing list I was able to get started.
I can make sip-to-sip calls (just on a basic extentions structure, let's say
for beginners) but now I'm trying to make this system works with my Teles
ISDN BRI PCI card.
I can make and receive calls through X-Ten
