rxgain / txgain for iaxmodem or hylafax
In trying to get the asterisk and faxing working
I had to resolve to using iaxmodem and hylafax.
I have incoming working, but outgoing the other fax rings
but it would appear from web searches that the fax signals
are too low to be "heard"
I can read about rxgain and txgain for zapata.
my fax setup goes direct from aterisk <-SIP-> SIP Provider <- Fax Machine ->

Problem with Action:Originate with ASterisk Manager
Hi Asterisk-users,
I am working with Aterisk Manager API's.
I can login successfuly with the following.
char buff[256];
strcpy(buff, "Action: Login\r\nUsername: admin\r\nSecret: unix\r\n\r\n");
send(msock, buff, 255);
Now I want to try Action: Originate, therefore I tried the following

How to configure Asterisk as a VoIP(SIP) to PSTN Gateway?
Hello,
I'm very new with * and I would really appreciate some help to implement
a SIP to PSTN Gateway.
My current scenario includes an * box with a TE405P board. I have a
1.5Mb connection to the outside world (using a router with firewall
capabilities) and channel banks that allow me to connect the T1s coming
out of the TE405 board to PSTN network (carrier).

UK VoIP-PSTN gateway recommendations
I'm looking for recommendations for UK-based VoIP-PSTN gateways.
They should ideally offer:
- IAX connection
- Multiple simultaneous calls on a single account
- Lower call rates than BT Business
- Auto-top up or invoicing in arrears
I can find several that offer one of these facilities, but none that offer
all.
Thanks!

SPA-3000 VOIP-PSTN gateway - long delay between answering and ringing
Greetings,
We are currently testing a Sipura SPA-3000 as a gateway from our
Asterisk system to a PSTN line for 911 access. We have a number of
locations and want to place an SPA-3000 in each, connected to a PSTN
line that will provide the correct ANI/ALI information to 911 for each
location.
It all works great, except for a reasonably significant (4 seconds)
delay between when the SPA-3000

voicemail email problem
Hi,
I just setup two voicemail boxes - but after they record the wav
file, they don't seem to email it even though i have the correct format
in my voicemail.conf file. Aterisk doesn't give me any feedback
besides the recording of the voip file... and then stays there.
Secondly, I can't get the Playback() function to work.
Thanks,

Refreshing DNS lookups
Hi there
The "dnsmgr" in Aterisk 1.4.0 seems not to work. I enabled "DNS lookups" in dnsmgr.conf but after reloading the conf files * never refreshes DNS lookups. Any ideas how to debug this issue?
Thanks in advance

High availability Asterisk
Hi folks,
I'm experimenting with Heartbeat and whilst I have it running in an
active/standby configuration I cannot get Asterisk to perform properly.
I'm able to start the asterisk software (I imported the aterisk start
file from /etc/init.d into /etc/ha.d/resource.d) with the heartbeat
software but heartbeat continues to start more Asterisk instances.
Any ideas?

Selecting outgoing trunk based on extension number
Hi all,
I have situation in that we are renting out a room in our office building to
another company, including the provision of phone lines via our Aterisk box.
To keep billing simple, we would like them to be billed separately for all
their calls. We think we can achieve this by them leasing their own outbound
IAX trunk (which our providers have said is no problem) and having all their

New to asterisk? RUN... don't walk.
As a newcomer to Asterisk, you will not be welcomed
with open arms. First, you will find almost no
documentation on it's features. Second, if you try to
ask questions, you will be flamed and pointed to
worthless how-tos and 'the wiki'. These worthless
documents can only be useful for explaining how things
work to those already in-the-know. Lastly, Asterisk

TDM Cards or PSTN>VOIP Gateways?
OK, I think I may have found the problem for myself at least. Actually,
a friend of mine suggested it. Apparently, Asterisk is a little too
fast for the card.
Placing a "w" in front of the number to insert a pause looks like it did
the trick!
Dial(ZAP/1/w5555555)
Looks like it gives the card a chance to come online?
So, at least in this case, it was not that Asterisk was keeping

PSTN to VoIP FXO gateways?
Sure would like to hear experiences using various FXO to VoIP gateways
with *. It seems that any thread that has anything to do with
problematic FXO interfaces goes on forever with speculation about
everything under the sun. Unless there is someone out there with the
engineering experience to build a better one it is a waste of time, let
Digium deal with it. If the TDM400P can ever be made 99.99%

IP-PSTN / PSTN-IP Gateway Service Providers
We manage our own VOIP solution using Asterisk.
Has anyone had success with an IP-PSTN provider? I'm looking for someone to terminate SIP calls to the PSTN in the Seattle, Washington area. (vice-versa as well if possible)
Yes, I could do it myself via asterisk and digium cards but I would like to consider other options.
Any opinions?
Thanks,

Asterisk 'losing' upstream provider registration state during small network outages.
Now that I have most everything actually working I've noticed that about
every 3-4 days on average..... and at worse... Once a day my asterisk box
seems to lose it's registered state with our sip provider and no longer will
take any incoming calls.
The caller simply hears a fast busy (reorder)
If I do a reload at the command prompt all is well for another few
days.....
