But it's possible that one of the intermediate transit providers is doing something clever. (Disabling ping, as you mention in your later email, is often a good indicator of a company with insufficient Clue.) Are you in a position to tunnel the traffic over a VPN or similarly flat and unfilterable network link? (This might be a good idea anyway.) Hello Roger, I'm not in a position to start doing that. The ping is disabled on the firewall that is also doing the NAT (not something the provider does). However the provider is blocking other things (incoming email for example, for outgoing it is something I can understand). The strange thing is it is dropping mid-call, that is the reason I don't think it is only a NAT problem. Another network we use offered us a server so we can test if it is related to the other network we use.

A good diagnostic tool to keep an eye on the broadband connections involved is smokeping http://oss.oetiker.ch/smokeping/ We find it an absolute godsend. === Hello, Ping is disabled on the location with most call problems (filtered). A few clients with dedicated audio broadband connections have the same problem compared to shared broadband connections. This makes it very difficult to find the problem. A supplier we use offered to test it with a server from them, if that solves it it was probably a network issue.

Re: [asterisk-users] A few questions regarding Asterisk 1.8.0
Good luck as with any new version there may be some bugs so if you bump up against ones report them so they can be fixed. Also don't just drop it into production with out testing it on a box for a bit. 1.8 has a lot of changes. Most appear to be for the better. The only important difference I could find while testing was that with 1.6.x you could use nat=route. This doesn't work anymore with 1.8.0 (and I didn't find it in the ChangeLog 1.8.0). Changing nat=route to nat=yes seems to work. (I mention it here so others can find it in the future).

[asterisk-users] A few questions regarding Asterisk 1.8.0
Hello, I have a few questions regarding Asterisk 1.8.0. If you can answer a question, please do so. Is Asterisk 1.8.0 stable enough for production environments? Is it possible (and if yes what is the best option) to use CDR MySQL with Asterisk 1.8.0? With 1.6.x we use the add-on package for that, however we could do something with scripts to do it (but I don't like the idea). If it is stable and there is a good option for CDR with MySQL we will start using it very soon.

Or is it better just to use a plain fax connected to an FXS and just switch with Asterisk. I specifically wanted to know if there was any experience using just the fax scanner to send faxes and receive them via asterisk and the to e-mail. My idea was to take my old fax connect it to an FXS port and send faxes with the fax machine (using the fax mainly as a scanner), but receive them through our existing FXO jack that is connected to the PSTN. the scheme would be something like: PSTN -- FXO - | |Asterisk | FAX -- FXS - I'm using Asterisk 1.4.26.2 on FreeBSD 8.0 Here we have the following setup, could you say if that is acceptable for you? Outgoing fax: Fax - Linksys pap2t (sip, no t38, for settings see http://www.provu.co.uk/pdf/sipura/ip_faxing_sipura_linksys.pdf) - asterisk - sip trunk provider (this could also be some sip - pstn solution I guess) Incoming fax: Sip trunk provider - asterisk - email For the incoming fax I use a separate context, below I've listed an example: exten = 1000,1,Answer exten = 1000,2,Set(FAXFILE=/var/spool/asterisk/fax/${CALLERID(num)}_${EPOCH}_client. tif) exten = 1000,3,Set(CLID=${CALLERID(num)}) exten = 1000,4,Set(EMAIL=email address) exten = 1000,5,Set(TRADENAME=tradename (used in the email)) exten = 1000,6,Wait(3) exten = 1000,7,ReceiveFax(${FAXFILE}) exten = 1000,8,Hangup exten = h,1,System(/usr/bin/php /etc/scripts/fax2mail.php ${FAXFILE} ${CLID} ${EMAIL} ${TRADENAME}) fax2mail.php (tiff2pdf and phpmailer are required): ?php $faxfile = $_SERVER[argv][1]; $callerid = $_SERVER[argv][2]; $email = $_SERVER[argv][3]; shell_exec(/usr/bin/tiff2pdf -o/var/spool/asterisk/fax/.$callerid..pdf .$faxfile); $bijlage = /var/spool/asterisk/fax/.$callerid..pdf; switch ( $_SERVER[argv][4] ) { case trade: $tradename = 'our trademark'; $from = 'f...@domain.tld';$fromname = $tradename.' - Fax system'; break; default: $tradename = 'our trademark'; $from = 'f...@domain.tld';$fromname = $tradename.' - Fax system'; break; } require(/etc/scripts/class.phpmailer.php); $mail = new PHPMailer(); // $mail-IsMail(); // telling the class to use Mail functie van PHP $mail-IsSMTP(); // telling the class to use SMTP $mail-Host = ; // SMTP server $mail-SMTPAuth = true; // turn on SMTP authentication $mail-Username = ; // SMTP username $mail-Password = ; // SMTP password $mail-From = $from; $mail-AddAddress($email); $mail-FromName = $fromname; $mail-AddAttachment($bijlage); $mail-Subject = Received fax from .$callerid; $mail-AddReplyTo = $email; $mail-IsHTML(false); $mail-Body = email body; $mail-Send(); //shell_exec(/bin/rm /var/spool/asterisk/fax/.$callerid..pdf .$faxfile); ? I agree that it isn't a beautiful solution, however it works. Sending a fax directly with asterisk is probably also possible (I didn't test it).

[asterisk-users] Confirm answering a call

Current situation: Incoming call - 3 SIP phones + 2 mobile phones ring - if mobile phone goes to voicemail the call is answered by that voicemail (if a phone is in use for another call the call directly goes to that voicemail) Situation I want: Incoming call - 3 SIP + 2 mobile phones ring - if the call is answered by a mobile phone the person picking up the call needs to press 1 (or another key on the phone) to answer the phone, if that key is not pressed all phones keep ringing as being it an unanswered call If it is also required to press the key on the SIP phones than that is acceptable.

I feel sure with some careful searching you can do much better for the card and the 6 phones. Coupling the two systems together will not be well received by the users. Just one opinion If you really want to move to Asterisk, then do it, but it will take more than a weekend of careful consideration and testing! We did something like that by a client not too long ago. First we did place the new phones next to the existing phones (so user could use it for outbound calls + intern calls and get familiar with it). After 2 weeks we did start the move for the incoming number and now they are using it for all calls (except the mobile phones). To explain everything to the persons that need to use it we did create a short manual and we give a few persons a special number to call if they need help. Currently we are planning to do the same thing at another client. We did decide to make options available on the asterisk server and not on the phone (as they also use PAP2T boxes at some locations and options have to work the same way everywhere).

I've used both the Grandstream 286 and the Linksys PAP2T. I have been able to get some limited faxing to work using T30 with a PAP2T. Configuration and provisioning of the Linksys is very easy through either the web GUI or XML configuration files, which can be transferred through TFTP or HTTP. I can only hope that Cisco will update the firmware of the PAP2T to support T38 one day... Related to this: what is a good ATA with a reasonable price that works correct for sending and receiving a fax? The faxes we have (on multiple locations) require a analog connection. We have sending a fax working with the PAP2T and incoming faxes are send to an email address (as a PDF).
