echotraining on T1 circuits
Hello,
We just had some new T1s turned up today to replace others that our contract
has run out on and we are now getting more echo on the new T1 lines than we
had on the old ones.
The T1 type is 24-channel, D4/AMI SF Robbed-bit(the same as the T1s they
replaced)
The problem is that we are getting echo on about 10% of the calls in and out
placed on these new T1s compared to less than 1% with

X101P on a UK BT line ---- txgain issue
I am finding that I have to increase the txgain in zapata.conf to 8 when my
X101P is connected to my BT phone line, otherwise people can hardly hear me.
This then gives echo issues.
Do other people have the same problem on BT lines. I was wondering if I
should give BT a call and get them to increase the gain on the line. Strange
though as the rxgain is OK and I don't have this problem with

RxFax - Fast carrier training failed
I'm trying to send a fax to my asterisk box, however shortly after
connecting the fax machine reports a "communication error" and hangs up.
Below is the error I get from RxFax: Fast carrier training failed
Nothing is written to the file system as far as the tiff is concerned.
Any ideas on how to fix this? Thanks

Can't transfer with Zap and SPA-2000
I am having trouble getting transfers to work when a zap channel is
part of the call. I have a couple SPA-2000's and some X100P cards as my
setup. This is what I'm trying:
Dial number from phone:

Currently on call:

Echo cancellation, when software doesn't cut it. Whats next?
Over the last couple weeks I've tried everything I could get my hands on
in an attempt to get rid of my echo problems. Using a CVS checkout of
just yesterday, I've tried every echo cancellation routine in zconfig.h
(including Mark2 w/Aggressive) , as well as the echotraining=800
mentioned on this list just last week.
While some things worked better then others, I would consider none

lost packets when bridging zap and iax
We have a machine with a TE410P in it acting as a client to route calls

often the called can't hear the caller (both machines on public ip)

Weird..bridging to Zap channel FXS instead of bridging to PSTN FXO on outgoing group
Hi All,
Channels 25-28 on a customers PBX are regular Zaptel FXO cards that
are hooked into 4 incomming phone lines. They are all in a group to do
automatic rollover for outgoing calls (if channel 25 is being used,
dial on channel 26, etc.).
Sometimes when a user is dialing a number, instead of bridging to one
of the FXO cards it goes and rings to Zap/1-1.
This doesnt occur all the time but some

Sipura SPA-841 Volume Oscillation Problem
Hi all,
The problem is on the volume of the voice sent by the SPA-841. I think the
echo cancel algorithm sets a limit to the microphone when detects sounds or
noise from the earphone. This problem generates an oscillation on the voice
volume sent by the phone and even turns it off completely for very little
lapses of time making the communication very uncomfortable. I manage three
different

Echo on Zaptel FXO :(
Hi All,
I've got an MD3200 modem which is working as a Zaptel FXO interface for
Asterisk (X100P clone I believe). It seems to work, but on incoming or
outgoing calls I can hear the other party ok but when I speak, I hear
my voice echo back at me (quite quietly but it's distracting!) on
everything I say. The other party doesn't seem to hear the echo - they
just say I sound a bit quiet.

echo / delay problem
I'm having with an echo or delay
I connect to the PSTN with a x100p and then connect a std. phone
to a FXS module on a TDM10B.
The std phone is only 2-wire so I know this is not helping.
(yes I have read the 2-wire 4-wire issue)
I have tried many echocancel values. The best thing to help was
rxgain and txgain. below is my current zapata.conf file

Fun with Echo
I've spent the last week or so troubleshooting echo problems at my
Wife's business, and I've been able to clear up about 99% of the
echo, but there is still a little residual echo that I can't seem to
"tweak out". The users describe it as "buzzing or crackling", but
what it sounds like to me is a slight echo, but just of one syllable
of the word.

Weird Zaphfc - not dialling non-local numbers
Hi all,
I really hope that you guys can help, because I've been tearing my hair
out for the past 5 hours on this one.
I have a Zaphfc (BRI) card in TE mode connected to the S-Bus of a Nortel
Meridian phone system. Phone calls from the Nortel to say MSN 510 are
correctly being sent to the right SIP phone. When asterisk dials say
Zap/g2/224 (a Nortel internal extension) the call goes

Nuvox PRI - CCITT (ITU??) vs. ANSI
All,
Having problems terminating to a Nuvox PRI, the tech at Nuvox is
saying Asterisk is transmitting in CCITT (aka ITU?) when they're
expecting (and will only accept) ANSI. The question is, is there a
simple way to change this or am I stuck with rewriting code? I googled
and checked the mailing list and found nothing, I could be barking up
the wrong tree I guess. PRI is not my forte.

Problems with ZAP Channels
Hi everyone,
Sometimes i am having problems with Zap channels on asterisk 1.2
(Disc-OS 1.1), after some calls, the channel continues in use, even
after hanging the call up, then
i need to run the "soft hangup Zap/<zapchannel>" in the asterisk CLI to
release the channel. Here is my zapata.conf:

having some troubles with the card, cause it aparently is stripping
some digits from the dialed number, we tested the same server with a
tdm400 and everything worked as expected.
We?ve already added "w" before the dialed number with no results, is

US CallerID and TDM04B
Hello All,
I have new TDM04B installed and working fine with Asterisk 1.0.5 built on RedHat 9.
All is working fine except CallerID that bothers me big time.
I have several Panasonic and Sony phones and CallerID works fine with it (when I plug in the line into phone instead into Asterisk I get CallerID) but fails with Asterisk.

Help! Echo problem even at T1 PRI?
Hello,
We have an asterisk setup at our client's site using a TE205P. The line to
telco is a 23 channels T1 PRI, however the line has random echo problems
(about 5-10% of the calls)!
Can anybody tell me if echo cancellation is really needed even at a T1 PRI
to the telco? Because people keep saying when they deploy voip solution in
Hong Kong using T1 PRI, there is no need of echo cancellation.

Bad ECHO problem after upgrade to HEAD version
I installed the HEAD version of Asterisk on January 24 and ever since then I have a really bad echo problem.
I have tried to go back to the stable version, but it won't install.
Anyone else having this trouble? Suggestions?
Thanks,
