It's mapped to blind transfer in features.conf -- If you want to use the

blind transfer feature, which I find easier than my phones' transfer 
features, remap it to ## in features.conf.  That way if you hit # it 
dtmfs through to the target IVR, but you can hit ## real quick to get 
the transfer function.

Or maybe I could refer you to the notes in the wiki: ;)
http://www.voip-info.org/wiki-Asterisk+config+features.conf

Using the blindxfer in [featuremap] section you can redefine the 
transfer key. For example, if the blindxfer is set to "##", transfer 
only happens when you press the "#" key twice very quickly. This solves 
a problem using Asterisk phones to call IVR systems such as those used 
by banks and credit card companies - "Enter you account number followed 
by the # key".

check irq supply on the * server -- When you run zttest do you maintain 
over 98%?  or like Steve suggested, the network may have congestion or 
other errors ethereal may help you figure out.

I had a polycom 500 that was doing this to my user, 301s and 501s 
wouldn't do it.  Not sure if that was network issues or something with 
the polycom itself.

Hi,

I'm having problems with the rxFax app.  One of the messages that appear
in
my console is:
Executing Set("SIP/something",
"FAXFILE=/var/spool/asterisk-fax/1137692307.5.tif") in new stack
    -- Executing RxFAX("SIP/something",
"/var/spool/asterisk-fax/1137692307.5.tif") in new stack
Jan 19 12:38:30 NOTICE[12008]: channel.c:1906 ast_read: Dropping
incompatible voice frame on SIP/something of format slin since our
native
format has changed to ulaw

"Dropping incompatible voice frame on SIP/something of format slin since
our
native format has changed to ulaw"

This seemed particularly important, but I can't really say why....Could
this
be why my faxes are often interrupting during transmission and giving me
errors on my PSTN fax machine that is used for sending the fax?

Mike

Hello,

some problems with transfer and zap...

one hfc-card in NT mode and one fritz isdn-card in server.
there is one gigaset SX353 isdn phone on the hfc-card.
anybody calls from external via capi and the call is bridged
to the zap-device. if you want to transfer the call via R-button on
the isdn-phone the caller get the music-on-hold. you get a dialtone
and dial - if the called person gets on phone - i will hang up the
phone. but the call did'nt transfer - the moh to the first caller
will not stop. how can i transfer the call?

i want to transfer back the origin call to the asterisk-server in an
extension for faxtransfer, so if anyone call and a faxtone is there i
want transfer it back, so that asterisk answer the call.

any ideas?

sorry for my bad english ;-)

Marcel Pennewiss

Hey Steve and everyone,

I looked at the configuration, and unless I am missing something I don't

think they are configured

# ztcfg  -vv
Zaptel Configuration
======================
Channel map:
0 channels configured.

In the zapata.conf file,  it is the sample version, but I didn't notice 
anything  in there that related to what you said. Or is it in a 
different file or location?

I am in the office now so I am able to provide some more information 
about the issue that I am having.
Here is the kernel if this helps Fedora core 4 -- 2.6.11-1.1369_FC4smp

I know that ztdummy is at least loaded now. Also as stated before there 
is nothing plugged into the T1 card. So I wasn't sure if that was 
causing a problem or not which is why I enabled ztdummy but it was not 
the first time I e-mailed you.

# lsmod | grep ztdummy
ztdummy                 7748  0
zaptel                192516  6 ztdummy,wct4xxp

If I look at the connections from tcpdump, I see my phone call coming 
in, but no traffic is being sent back to the phone. With an Echo() test,

I see the traffic going back and forth, but when I call into a menu, 
then there is nothing.

Thanks,
Kevin

I ran a sip debug as well but I felt it was better at the end of the 
e-mail:

Just look through the devices settings for suppress silence or transmit
silence and don't supress or prevent transmission... this is a common
problem inX-Lite

I should be able do so this weekend. That's the plan, anyway :-)

I'll post the Mantis bug# when I've submitted it.

I designed a virtualized san and have been running it in production for 
the last two years...  Speaking from experience... stay away from EMC!  
We have several storage systems in production.. from multiple vendors...

and I've had nothing but problems with the CX line of emc systems.  
Performance problems... hardware/crashing problems..  (they run embedded

xp you know) and dead fibre port problems.  If I didn't have two of 
everything.. mirroring across cabinets with IpStor we would have had 
serious problems.

Just my two cents on the issue of 'EMC-caliber' storage...

Anybody knows if it's possible to disable zap echo cancellor from 
dialplan only for certain outbound calls ??

I share the same phone lines for voice calls and faxes. Iaxmodem works 
fine for me only turning off  the echo cancellor, but I need it for 
voice calls.
Any ideas ?
