Delay after Answer
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.

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

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

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

Automatic Gain Control
Is there any possibility of DAHDI supporting Automatic gain control on 
TDM ports?  I'm having issues at a couple of offices where calls made to 
local numbers are fine but a when a calls from or goes to a large 
percentage of long-distance or 1-800 numbers the person at the remote 
end cannot hear the person in my office.  Boosting the gains in

Sip Trunking
I have several branch offices, each with their own Asterisk server 
(version 1.4.22.1) handling their PBX functions.  All of these offices 
need to talk to each other.  In sip.conf I created a peer entry for each 
office with a username of branch-user and a friend entry for every 
branch-user with the username being just the branch, for example:
[Office2]
username=Office1-user
host=10.10.80.253

VPN
Hi list, I am trying to create a VPN between two different locations. On 
the first location we have a cisco pix 525 Natting the internal 
192.168.100.x network, while on the second location we have a Centos3 
box Natting via iptables the internal 192.168.10.x netowrk. My goal is 
to connect this 2 over the internet via IPsec. I created the IPsec

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

Betr.: VPN
IF you are not stuck to IPSec, you might want to take a look at OpenVPN (www.openvpn.org). I found OpenVPN easier to install than FreeSWAN (an IPSEC VPN) and have setup an OpenVPN solution between my German office and our mainoffice in a matter of hours.

Variable Scope Question
If I have a global variable in my dialplan and I change it, does that 
change immediately take affect for all calls that are active?
Here is my situation.  The company I work for has two office groups that 
share a building.  The two offices are separate companies but support 
one another and want to be able to transfer calls as if they were all on 
the same phone system.  Each company has 4

Hey Everyone,
 
We are in the works of planning a new * installation for our company.
We have 20 users in our main office and 5 users in a remote office a
couple of states away.  Our call volume for the main office will be
anywhere from 5-10 concurrent calls.  The remote office will have about
3 heavy users with two users making calls occasionally.
 
Right now we have an existing PBX.  We have a

VoIP QoS with PIX
Hi List
Just a little bit OT, but then again perhaps an information that could be of
great value for a lot of administrators !!
Does anyone have experience with how to setup VoIP QoS for outgoing data
through a Cisco PIX (515) ?
I believe that it should be possible to give higher priority to outgoing
VoIP packets. This is due to the problem of ADSL as the UpStream data rate
is 1/4 of the

Asterisk behind a PIX firewall?
Is there anything special that anyone here has had to do to get an Aastra
phone (on the Internet) to talk to Asterisk behind a PIX firewall?
Ports 10000-20000 UDP are open on the PIX and forwarding to the Asterisk
server.   The Asterisk server's RTP.CONF is set to use 10000-20000.    The
phone registers, and will place AND receive calls, however, no audio is
passed.   The phone is an Aastra

Calls being disconnected across VPN
Hey All,
 
Sometimes we are running into issues with calls randomly being
disconnected.  We have a couple of phones is in a remote office.  We
have a PIX-to-PIX VPN setup between the offices.  I know neither of
these devices provide QOS but we usually don't run into any problems.  I
notice this problem when we are in a conference call with one of the
employees at the remote office and a

IPtables Possibility
Hi,
I just wonder if I can replace PIX firewall with machine having IPTable as my firewall. I want to control our firewall but 
due to the lack of knowledge in configuring PIX, i want to replace it with Linux or BSD. I do not have the time now to
learn the complexity of PIX and yet I want to know what happening in my firewall and control it as much as possible. 
Do you think it is justifiable for

"ring splash"
Something new to me.  Recently installed a 1.4.30 box for a small office 
with four POTS lines in a hunt (Digium TDM410P).  Had the telco put a 
"call forward" option on the main line of the hunt.  They dial a feature 
code from their desk phones (Polycom IP450) that results in forwarding the 
main number to our VoIP service.  This is all to let them "try out" our

VPN As SIP Tunneling?
Hi All
Could a VPN be used to help with SIP Tunneling and QoS issues.
State 1:
Two IP Networks Connected via the Public Internet transmitting VoIP Traffic
Say a VoIP User and VoIP Termination Provider.
Each side can put QoS onto their part, but if QoS does NOT exist between 
them
then call quality will be bad anyhow.
State 2:
Same as above except a VPN tunnel is setup between each side.
Thus

QOS Wishes
Hello all,
It would be a great feature if QOS could be implemented in Tinc.
It's not to do any sort of comparison, but with OpenVPN, the traffic can
be shapped.
In the way that tinc works as mesh VPN, the great feature would be to
fix a shapping value on each nodes, known and respected by each others.
(like MPLS does)
As an exemple, you've got 3 nodes A,B and C, you want Tinc flows on A
