PSTN Incoming call on real line disrupts VoIPcall over DSL circuit - EXPLAINED
DSL works by using the frequencies above 4k that were unused in POTS loops of yesterday. Load Coils, Bridge Taps, and DC taps are all devices added to lines to increase their reach and stability, unfortunately, they are DEADLY for DSL. Other problems can effect DSL service, and cause it to be 'flaky'.

PSTN Incoming call on real line disrupts VoIP call over DSL circuit
I haven't seen anything this strange, and it's 100% reproducible. I'm
hoping that there are some clever ideas out there for what to look for,
since I can test to my heart's desire on this one...
My Dad lives in Florida, and has a Bellsouth DSL line. Of course, he has
a regular POTS line connected on the same line. He has the appropriate
filters on every jack that has a phone

[Asterisk-Dev] Severe ISDN signal distortion in CVS-HEAD with octoBRI
BUG/SYMPTOMS:
1.Under certain circumstances, octoBRI (and most likely quadBRI) ISDN
cards (Junghanns/CologneChip) severely distort certain ISDN payload.
2.Although these claims relate to the bristuff patch, the problem might
not be limited to bristuff and in fact be rather asterisk/zaptel/libpri
related.
3.Signal distortion is limited to the use of the CVS version of the

G729 question
I am thinking about using the G729 codecs on my endpoint devices and
purchasing some G729 licenses for Asterisk but I have several questions:
1. Which G729 codec is sold by Digium for Asterisk, G729, G729A, B...I?
2. If I have G729A on one end and G729B on the other, are they compatible?
I have looked all over the place for question 2, but without buying the

Audio distorted local side only
I'm not sure where to check next, so I'm reaching out to those that
know this stuff better than I.
I've got Asterisk up and running, but I've still got an occasional
audio issue. Once in a while (maybe 1 out of every 20-30 calls), the
audio becomes heavily distorted, but only on the local side. The party
on the other end says the audio is fine. We can hear them, although

local echo using SPA-3000 as FXO port
Hi All,
Last week I started hearing a huge amount of local end echo on
incomming calls. I am using a Sipura SPA-3000 as my FXO connected to an
SBC POTS line. Echo cancellation is enabled in the SPA firmware.
As a test I switched to a Digium X100 card the still lives in my server
but the echo was about the same. I have both Polycom IP600 and SNOM 200
phone, which both hear the echo.

Re: Echo and other reasons to migrate to BRI
Brent-
There is no good way to say what changing the hardware and PSTN hookup will
probably do for the echo problems. I'm not sure if you mentioned (lost in
the past history of your post now) what sort of hardware you're using for
PSTN connection now- TDMs, X100s, ATA's, etc- but that could also be a
potential cause. I've heard tell of aftermarket X100s and certain ATA's

Homework help: Is this how CIs of normal distributions are computed?
I'm looking for a function in R similar to t.test() which was generously
pointed out to me yesterday, but which can be used for normally
distributed data.

IXJ card doesn't want to dial out (see previous thread, asterisk won't answer pstn ring)
Hi all,
Currently trying to get asterisk to dial out with an Internet Line Jack card,
however, it does not use the pots line, only on the line it dials out of. This
is similar to the previous thread/posting "Asterisk won't answer pstn ring",
but I didn't find any follow up to get it working.
My asterisk setup is like this:

[RTP] PSTN -> Gateway -> Phone
Hello
I'm using a Linksys 3102 as VoIP gateway to connect a POTS line to a PBX. I
also have an IP phone in a remote network across the Net. The PBX +
gateway, and the phone are both behind a NAT router.
I was wondering:
1. When a customer calls us through the POTS line and I pick up the call
with the remote IP phone, do RTP packets go directly from the VoIP gateway
to the IP phone, or

How to use Sipura SPA3k POTS line to dial Asterisk SIP phones?
My SIP phones can dial out through Sipura SPA3k to POTS for local and
911 calls _but_ incoming POTS calls are being swallowup somehow.
Am I on the right track with the code snippit below?

In sip.conf the following code is _supposed_ to ring the SIP phones when

shading (fill) the area between two lines

I am trying to shade the area between the two lines; *line 1* and *line 2*.
You can use this code as an example.

X100P "rings" randomly when "phone" line makes call
Not sure if anyone experienced the same - or if anyone ever connected a POTS
phone to the "Phone" jack on an X100P card.
The POTS phone rings normally when the FXO receives a call. The POTS phone
can also make outgoing calls when FXO is not holding the line. This is
desired. But if a call connected to the POTS phone lasts longer than a
couple of minutes, Asterisk would receive

PSTN to VoIP
I'm about to purchase an adaptor for a POTS data modem and was looking at
the Sipura line of adaptors (SPA-1000, SPA-1001, SPA-2000, SPA-3000). Do
these work well? Anyone have a suggestion on which model of the Sipura I
should get? Does one work better with * than the others? Are there other
adaptors that work better that I should get?
Thanks,

Distorted Audio for incoming DTMF
Does anyone have any idea what would cause distorted audio but ONLY for
DTMF tones coming in over our analog lines. (The analog interfaces are
X100P's). I have carefully adjusted the gains in the zapata.conf using
a local test line after trying various settings with no gain or just
random gain settings. RelaxDTMF has no effect. I set up a monitor

one-line fix reduces distortion
Ok maybe it's just my imagination, but it looks like the one-line "duh"
fix I committed from Andrej Vakrcka <ander@cauldron.sk> this week
DRAMATICALLY reduces distortion in encoded files.

Asterisk to make multiple extensions simultaneous calls on a single telephone line
Hi Lists,
I have one box with two FXO and two FXS ports, it is running asterisk
inside. I have one sinle POTS line connected to the one FXO and two
phone sets connected to the FXS port.
Extension 6003 is asigned to one fxs and 6004 is asigned to another
fxs, the two extensions can call each other, they can both
make/receive PSTN call, but they can't make PSTN call simultaneously.
Is it
