sporadic one-way audio
We have several offices running Asterisk version 1.4.20.1, and OSLEC
with Rhino R4FXO-EC and one running a Digium TDM800P card for interface
to analog lines. All offices are running Snom 300 phones. Phones all
have static addresses and are on the same physical network as the server.
The problem we are having is that every so often we get someone calling
in where we can hear their voice,

Snom 300 Echo
We're deploying an asterisk-based phone system at all of our branch
offices in an effort to eliminate long-distance costs incurred from the
constant branch to branch calls. We're using the Snom 300's at all
offices for the desk phones and X100P cards to interface to 2 analog
lines. I'm having a problem tuning all the echo out of the system. So
far two branches are using the

Delay after Answer
I am having an issue with a couple of phones where they ring, but there
is a long delay after the phone is picked up before the audio starts.
My setup:
* Server running Asterisk 13.9.1, Dahdi 2.11.1 w/ OSLEC
* Server is CentOS 7
* Quad core CPU with 16GB Ram
* 2 Snom 300 phones.
* NO NAT. Server and phone are on the same subnet with only a gigabit
switch between them.
* Digium

Audio cut-outs
I'm having an issue with some Snom 300s on a server running Asterisk
version 13.9.1, Dahdi 2.11.1 w/OSLEC and pjsip 2.5.1. There is _*NO
NAT*_ involved. Phones and server are plugged into the same network
switch, all on the same IP range. The server is running a Wildcard
AEX410 analog card with 2 FXO modules receiving incoming analog lines.
Occasionally, in the middle of a call, the

Well, I thought I had the problem solved. Ported everything over to
PJSip and build RDNS records for the phones and the server, but I am
still experiencing the problem on incoming calls.

Sporadic One Way Audio
I'm having an unusual problem at one of my branch offices. Every now
and then they will make a call and the person they call is unable to
hear them, but they are able to hear the person. The Asterisk server
has only one ethernet interface and is on the same physical network as
the 2 snom 300 phones and is connected to the PSTN lines with a Rhino
R4FXO-EC card. Usually hanging up and

Intermittent DTMF Problems
I've recently installed Asterisk-based servers at several of our branch
offices. Each server has 2 X100P cards to handle 2 incoming voice
lines. I was having a lot of trouble with Echo until I got OSLEC
running on all of the servers, but now we have a new problem. Incoming
callers are not always able to dial extensions. I would say probably
95% of the calls go through correctly, but

Dropped Calls
I've written about this issue several times, but have not yet found any
solution to it. I am using asterisk 1.4.21.2 and zaptel 1.4.12. Phones
are primarily Snom 300's but I also have a couple of headset phones
connected to Grandstream HT286 SIP adapters. I have 8 offices, each has
it's own asterisk server all running the same versions of asterisk and
Zaptel. Only difference

Phantom Rings
I'm having a major problem at one of my branch offices with "Phantom
Rings" on their asterisk-based phone system. The system was originally
built using 2 X100P cards and was recently upgraded to a Rhino R4FXO-EC
card. The upgrade severely increased the frequency of the phantom
rings. I've read everything I can find on-line about automatic testing
and noise on the line and

How to set a HA8 board + B400M in NT mode ?
Hi,
1. Is there any manual entry about modprobe's options relative to a given
Dahdi driver (wctdm24xxp, for instance) ?
2. When loading a wctdm24xxp driver, is there any parameter to pass to
modprobe to configure a span in NT/point to point mode ?
3. After running dahdi_cfg -vvvvv , I can read with dmesg :
[ 1986.289277] wctdm24xxp 0000:04:06.0: xhfc: Configuring port 0 span 1 in

More DTMF issues
Still grasping at straws trying to solve DTMF detection issues with one
of my asterisk servers. This particular server is now running Asterisk
1.4.18.1 and Zaptel 1.4.9.2 in runlevel 3 (console only) with 2 X100P
cards. I have tried adjusting channel gains, turning call progress and
relaxdtmf on and off, switching echo cancelers, just about everything
that Google turns up and I can't

QoS & VPN
I've got multiple satellite office all linked back to the main office
via VPN. Each office has their own asterisk server which registers back
to the main office's Asterisk server. Each office also has a 1Mb

Speex for their connections back to the main office. The issue I'm

Transfer/Park Question.
I've got a situation where I need to use a transfer to the parking lot
as hold, but am not going to use BLF indicators on the phone to pick up
the parked calls so I need to hear the 3-digit extension after the
transfer. I'm using Snom 300 phones and have tried setting a
