Looking For PRI Card With Automatic Fail Over

Report
Question

Hi all,

Strange request, I have a customer where we are putting an Asterisk PBX in front of a legacy (non-VoIP) PBX. One of the requirements it that the Asterisk PBX have 2 PRI ports (on towards the legacy PBX and one towards the carrier) with the ability to go to pass through should the Asterisk PBX (software or hardware level) fail.

I did not see this feature in the Digium, Sangoma, Allo, or OpenVox cards.

Does anyone know of a card that will do this? I know that Digium has an external box (the r850) that does something similar for 2 PBXs…

Modifying CDR Values From A Hangup Extension In Asterisk 13

Report
Question

Hi,

I'm trying to migrate from Asterisk 1.8 to Asterisk 13 and can't figure this one out. I'm pretty sure the question has been already asked, but I failed to find a solution.

Can you modify CDR values in an h-extension?

My cdr.conf contains: [general] enable=yes unanswered=yes endbeforehexten=yes initiatedseconds=no batch=no

The diaplan contains a simple "h" extension exten => h,1,NoOp(${CDR(userfield)}) exten => h,n,Set(CDR(userfield)=changed) exten => h,n,NoOp(${CDR(userfield)})

In the same context I execute: exten => 10,1,Set(CDR(userfield)=empty) exten => 10,n,Dial(SIP/10)

The "h" extension outputs two lines with userfield set to "empty". I would expect the second one to be "changed". It seems that I can read the CDR…

SIP Phones Over VPN Drop Audio One-Way

Report
Question

Hello,

I am running Asterisk 11 on CentOS 6.x using the DAHDI module with 8x PSTN analog phone lines for outside connectivity. Internally, I am using several models of Yealink SIP phones (e.g SIP-T32G) on a dedicated VoIP network, 192.168.0.0/24. I have a few of these Yealink SIP phones configured with an OpenVPN certificate so that users working remotely can directly access the phone system (VPN subnet is 192.168.1.0/24). Note that this is not a NAT; VPN clients are able to directly address the Asterisk server and other SIP phones. Last week the phones connecting over the VPN started dropping audio…

Call Center

Report
Question

Has anyone used Asterisk for a Call Center operation? What I mean is: given a list of phone numbers, can Asterisk dial each number, play a message and accept some DTMF? I ask because I am an employee of a non-profit company based in San Diego, CA. I already evaluated Voicent and Voxeo. The former has expensive licensing terms and the latter is not best suited for a call center. I would appreciate your kind comments.

Insecure Meaning.

Report
Question

Hi all,

When configuring an extension on Asterisk we use the Syntax "Insecure=very " or "Insecure=port" etc. I did some research on Internet and I found that this is used to authenticate the peers, based on their IP/port. But I couldn't understand what's the difference between them.

The following page gives a simple explanation :

http://www.voip-info.org/wiki/view/Asterisk+sip+insecure

insecure=port ; Allow matching of peer by IP address without matching port number insecure = no; Normal IP-based peers matching and authentication of incoming INVITE. insecure=very ; To allow registered hosts to call without re-authenticating insecure=port,invite ; (both).

Can someone provide more details about this, or any…

CEL Eventtime Incorrect, But CDR Times Are Correct - 1.8.11.0

Report
Question

Hi list

I have a huge problem with a 1.8.11.0 Asterisk instance not logging CEL events with the correct eventtimes.

I'm logging via ODBC to MariaDB 15.1 Distrib 10.0.20-MariaDB

I'm logging into a MyISAM table.

If I start the Asterisk instance, logged times are correct, but the longer the box runs the more the eventtime in the CEL rows created by Asterisk via ODBC drift backwards.

E. g. the clock on the server says 08:15 for example (I enter the date "command" in the terminal) and if I run a query and check the most recent CELs immediately and about ten minutes after startup, they…
