Hi, I try to find some information about CAS E1 signalling and how it's handled by Asterisk. My customer wants to connect to a BT ITS Netrix by CAS E1 E&M. The system is intended to take the channels and mix them (meetme / confbridge) and send the audio back mixed to each. The layout: BT ITS Netrix: CAS E1 E&M <-> MUX - WAN - MUX <-> Digium TE220, Asterisk I've

Hello, i'm using a TE410P on some E1/PRI with EuroISDN and experiencing a few audio quality problems with current CVS (both zaptel and asterisk) and the following network ISDN public SIP/zaptel network ---- pri --- ASTERISK GW --- iax --- ASTERISK PBX --- PHONES w/ any codec the rx (public network to local

Hello everyone. I am looking for a E1 PRI card which supports network side signaling not CPE. The main idea is to connect an plain old E1 compliant PBX which doesn't have an VoIP module to the newly created VoIP infrastructure. Could we use a Digium TE122P or something other to resolve this situation? Thanks in advance. Dimitar -------------- next part -------------- An HTML attachment was

Hi, I spent the past week experimenting with webrtc + asterisk 11.9.0-rc1 + opus/vb8 codec patch. This is interesting technology and I try to find out how to connect all the moving parts. Firefox: Neither sipml5 or jssip works with calls to asterisk, audio/video doesn't matter. WARNING[977][C-00000005] chan_sip.c: Rejecting secure audio stream without encryption details: audio 35684

Hi, I'm trying to connect a PC with a TE410P to an E1/IP equipment. Unfortunately I keep getting a yellow alarm from zaptel (in zttool) and a Loss of Framing alarm on the remote equipment. The E1/IP is connected on the other side to a PRI interface on a GSM MSC. I have configured the span as: span=1,1,0,ccs,hdb3 (also tried span=1,0,0,ccs,hdb3) and the channels as: bchan=1-15,17-31

Hi, I am about to purchase an Eurotech PRI E1 GSM & CDMA Gateway to operate with my Asterisk's TE412P interface. Anyone here has any experience of having this combination? Any success or failure stories would be greatly appreciated. Thanks in advance. Ash

hi, i have the problem that i'm not able to set and receive the Service Indication (SIN) from our E1-PRI and from our ericsson BP250. The problem is, that the Bearer Capability (BC) together with the High Level Compatibility (HLC) and Low Level Compatibility (LLC) forms the Service Indicator (SIN). The SIN is used to determine if the call is voice, fax or data. It's essential to set

Hi everyone, I'd like to try to use * & ASTCC to create a pre-paid public call card solution. In testing is looks good. I've been talking with Telecom suppliers about supplying me with E1 Primary ISDN lines (probably 4 to start with) and I'd purchase digium TE405Ps to connect everything up. What I'm uncertain about is how to handle CPC with asterisk. I know that 2mbit E1

Hi All, Can anyone recommend any test kit that you can hook up your Pri/Bri cards to without having actual ISDN in your office. For example testing an * system before it goes to a clients office. Thanks, Gavin.

Hi, I had previously posted about connecting an AS5300 to * via SIP/H323. I got it to work via SIP, but only 1 call at a time would work, and if a user from the * side hung up, the cisco would'nt catch the hangup. I an now trying to hook up to the cisco via E1, with a Sangoma A101 card in my * box. I would like it such that I call from * via E1/PRI to the cisco, and call out via R2 to

At the same site, DTMF recognition is functioning badly, sometimes duplicating digits and sometimes totally missing others. We have checked already /proc/interrups, there is no interrupt being shared. Our zaptel has .. span=1,1,0,ccs,hdb3 On zapata we have ... switchtype=euroisdn signalling=pri_cpe relaxdtmf=no (yes doesn't seem to help) -----Original Message----- From:

Hi i want change my asterisk server. Actually, Asterisk work's on a IBM Server with a internal digium E1 card. For High availability, i don't want now use "internal E1" card. In my new asterisk systems, i have two server and two E1 not in the same site. I am search a hardware gateway, if possible in 1U Rack with 2/4 or 8 E1 capacity with echo cancellation. I want that this

Hi All, I know this is not specifically Asterisk related but I don't knew where else to ask for help. Does anyone know how to or if it is even possible to allocate 512kbit/s to an ISDN device from a 30B+D ISDN line. The building the office is in has a E1 30 channel service (30B+D) but we can not get any 2B+D ISDN services. I have a HDX Polycom video conferencing system that requires a

I have been asked by a potential customer whether we can connect an Asterisk box to an Ericsson MD110 that has an E1 port with ISDN-USR. They are unable or unwilling to upgrade their E1 port to QSIG. Has anyone here had experience of successfully making such a connection? I have found a couple of hits on Google that suggest it "should" work, but I'm after something a little more

Hi All, I am installing a Zaptel Quad E1 card with ISDN PRI in Brazil and I?m with this problem: Asterisk CLI : Mar 27 01:49:57 WARNING[2612]: chan_zap.c:7143 zt_pri_error: PRI: !!

Hi, I'm doing an evaluation of Confbridge (migrating from Meetme). Looking at: https://wiki.asterisk.org/wiki/display/AST/ConfBridge+10 Under the heading "User Profile Configuration Options" the option announce_only_user is present. The sample config looks like this: -- ;announce_only_user=yes ;Sets if the only user announcement should be played when a channel enters a empty

After sometime I got my E1 PRI configured correctly in /etc/zaptel.conf and I now don't see any alarms on the E1, but I can't still dialout correctly, I enable every debug that I could though of and this is what I see: At the end the D-channel is down and I cannot even try to connect another call because it tell me that the zap channel is unavailable ,the other this that I notice is that I

Hi, I'm looking for a mean to send digital data over an E1 line, just like isdn4linux or Capi via AVM's FritzCard is able to do it with BRI lines (e.g. for PPP or ISDN raw connections). I'm not looking for modulated audio data representing digital data, like fax or the analogue modems of former times. I want an interface to the ISDN raw data, with an outgoing call marked as

Hi. I'm looking at ordering a 30-channel ISDN connection from telia (a swedish operator) and then using a Wildcard TE110P card with that and asterisk to do IVR. Can I be certain that the TE110P card will work with that ISDN connection? A 30 channel ISDN certainly sounds like an E1 connection, but I couldn't get any clear answers from the operator if it is. Has anyone used the TE110P
