Hello, We have a quadBRI in NT mode with bri_cpe_ptmp signalling and when connect a ISDN telephone to this nothings happen. What can I do? My config files are this: Zaptel.conf: loadzone=es defaultzone=es # qozap span definitions # most of the values should be bogus because we are not really zaptel span=1,1,3,ccs,ami span=2,1,3,ccs,ami span=3,1,3,ccs,ami span=4,1,3,ccs,ami bchan=1,2 dchan=3

Hi All, I want to configure fax with Asterisk and I found that we can do this reliably using G711 codec only. Currently my provider is supporting G729 and G711. During the call initiation the call starts with G729 (1'st priority) and somehow if the receiver is unable to receive call then we are providing the Caller to send a fax, but at that point they are using G729 codec. At this point how

Hello everybody, Just was wondering if somebody can help for G711 fax passthrough w/ asterisk. The issue I have is regarding codec upspeed when the call is already connected using G729 for example. The setup is fax---ATA---asterisk---Cisco---fax When codec upspeed should happen, ATA or Cisco will send a G711 reINVITE causing the codec to be switched over, but asterisk does NOT

If this has been covered before - I appologize. We use some Sipura SPA-2000's with the g711 codec and all seems fine (except for the occasional failure to register errors in my asterisk logs - but I will save that for another post). g711 call quality is on par with our Cisco 7960's. However, when using the g729 codec, the call quality on the Sipura device goes downhill on the PSTN side

Does anybody has got the some problem? The grandstream ATA 486 schould support almost all codecs, but it doesn't work. I get the following message when I force the use of different codec WARNING[9529]: chan_sip.c:2765 process_sdp: No compatible codecs! Feb 3 11:17:15 NOTICE[9529]: chan_sip.c:7395 handle_request: Unable to create/find channel What could I do to see some more detailed

Hello, I am a newer on asterisk. when I tried to send fax, I can not get success. After doing a lot of reseach, I decide to ask my question at here. Instead of using old fax machine, I want my system can send fax via t.38. Could anyone give me some idea to correct my configuration? Thanks a lot! Here is the detail: my system: *ubuntu 14.04 + asterisk 11.7* I use apt-get to install the ubuntu

Hi All, Can someone explain to me the difference between g711's ulaw and alaw codecs? Is it just different header info or is the actual payload in each encoded differently? I have thus far noe been able to find any difinative information onthe matter. All I've managed to find out that they are "similar", they sound the same and that it doesn't matter which you use. Could

Anyone have a customer sending/receiving multi-page faxes over Verizon Business SIP trunk/g711 ? Verizon Business indicates they don't support it, and I have 2 recent customers that it doesn't work for, and 1 current large customer telling me he's going to make it work <grin>. The issues is the latency/jitter on fax/g711 over Verizon Business seems to spit out only 11

I have a site where Users can become Friends with other Users. I used to do this with a habtm, but of course I want to stay up-to-date and convert this to a has_many :trough. Unfortunately I can''t get it to work.. the documentation on this feature is a bit sparse at the moment. This is my old habtm: has_and_belongs_to_many :friends, :join_table => ''user_friends'',

A few things you might try: 1. Verify ssh is listening: netstat -antp | grep :22 | grep -i listen 2. Verify you can ssh locally: ssh localhost 3. Try to telnet to ssh port: telnet <ipaddr> 22 4. run nmap against the ipaddress to verify port 22 is seen. Hope this helps.

Hi, I get error when my DID hit to asterisk box which I am using for FAX to Email Service. Sometimes Fax goes through but mostly I get communication error on Fax Machine and on Asterisk I get Comfort noise support incomplete in Asterisk (RFC 3389) error. I am using SIP with G711. My Did provider cannot turn off VAD and Echo from his side, so is there any option or setting I can do at my side to

hello everyone, i have question about fax detection on dahdi channels. does dahdi channels detect fax and pass it? if yes, does it detects both types of fax (g711 pass through and T.38)? finally, how can i enable it on dahdi_channels? i set faxdetect=both in chan_dahdi.conf but dahdi can not pass fax(i just wanna pass fax not send or receive it). any comments or hints are really appreciated.

Hi Robert, I have almost no experience with CentOS 7(still using CentOS 6). However, I recommed the following checks: 1. Check that PostgreSQL is listening on 0.0.0.0 (all ip addresses) and not 127.0.0.1. To check, you can use the command: netstat -tuplan If PostgreSQL is listening only on 127.0.0.1, you'll never be able to connect to it from the network. You'll have to change the

Hi All, This is our 2nd E1 client that we try to use crc4 either with the e100p or with the e405p without luck. After some trials, we ask the telco to switch off crc4 on their side and everything works flawlessly. Is there anything in the crc4 calculation that may be broken? We took a look at wct1xxx.c and wct4xx.c but there doesn't seem to be much there to be fixed (apparently the crc4

Customer has a Verizon Business SIP trunk, I'm still used to PRI T1 myself for local service. The fax machines are having some issues (I can use analog phone to call out fine) and I'm checking on modem passthrough with Verizon, but wonder if any else is using Verizon Business for SIP trunk and what your faxing milage was? Did they support G711 and modem-passthough, etc? Also checking
