Joining several FS servers in different regions
by Oivvio Polite 07 Mar '16

07 Mar '16

I'm working on a Saas service that will connect WebRTC (with SIP or Verto for signaling) clients to one another and to PSTN. I'm aware of other such services, but this is tailored to a specific niche. I also want WebRTC media to flow through FS, rather than P2P, so that I can record it. The primary markets are Europe and North America. To keep latency low I need to have servers on both continents. Later on I might want to add more regions. I'm not too worried about high availability or high loads. The clients can keep track of which FS is closest to them and register with that. But this still leaves me with a couple of questions. 1. Maintaining a single user database ===================================== What's the simplest way of maintaining one joint user database? (User directory in FS parlance). The first thing that comes to mind is to generate the xml dynamically from a central database, and force as `reloadxml` on all servers every time there's an update. The communication between central database and FS servers could be via RabbitMQ. mod_xml_curl could also be a part of this I guess. How does that sound? Is there an other simpler way of achiving my goal that I'm not seeing? 2. Keeping track of where a user i currently registered ======================================================= Let's say I have a client Alice who's registered with a FS server in North America and a client Bob who has registered wit a FS server in Europe. Now Alice tries to call Bob. How does the North America server know that Bob is currently registered with the Europe server and that the call should be routed through there? For this second problem I don't even have a tentative solution so I'm curious to hear any ideas. 3. SIP Trunks and geography =========================== If Alice is in North America and wants to call a PSTN endpoint in North America I should obviously be using a SIP trunk in North America, since going over the Atlantic twice will add a lot of latency. But what about when Alice want to call a PSTN endpoint in Europe? Is it better to use a SIP endpoint in Europe or in North America? Thanks in advance Oivvio

SSL certificate and webrtc
by Gregor Nanger 06 Mar '16

06 Mar '16

Hi! I bought wildcard certificate for using it with freeswitch. Now I have hard time to install it into Freeswitch and would appreciate any help. I have private key (generated at CSR request), certificate issued by authority and root certificate from authority. Now I do not know where to enter certficate. According to documentation I assume that this is correct: Cert, Key and Chain(s) are all contained in a single file in this order: -----BEGIN CERTIFICATE----- <cert> -----END CERTIFICATE----- -----BEGIN RSA PRIVATE KEY----- <key> -----END RSA PRIVATE KEY----- -----BEGIN CERTIFICATE----- <chain> -----END CERTIFICATE----- What is puzzling me is if this is correct: <cert> = root certificate from authority <key> = private key <chain> = public certificate issued by authority Would this work?

Hi, We are starting here again the debate of open cource vs. commercial software. Our current PBX holds more than 8,000 extensions. Is there an organization that uses Freeswitch having a few thousands of extensions? I need examples... Thanks! __Yehavi:

mod_local_stream strange behavior
by Igor Olhovskiy 04 Mar '16

04 Mar '16

Hello, Having a strange issue with a MoH and ringback tones defined with local_stream. Idea is I’m having 1 wav file for MoH. And when I’m playing it, it starts not from beginning, but nearly 3-7 seconds before file end and than - starts over. Can’t get why it not just playing file from start. Yes, I know there is a workaround to use file_stream, but may be there is way to make local_stream with a same behavior? System: Debian 8, VmWare ESXi, FS 1.6.6 (FusionPBX) <directory name=«Domain_name/TestingMoH/8000» path=«$${sounds_dir}/Domain_name/TestingMoH/8000»> <param name="rate" value="8000"/> <param name="shuffle" value="true"/> <param name="channels" value="1"/> <param name="interval" value="20"/> <param name="timer-name" value="soft"/> </directory> Or I’m missing some parameter? -- Best regards, Igor

XML CDR resend curl command
by John Nash 03 Mar '16

03 Mar '16

When using XML CDR to resubmit XML CDR I have a shell script which resends XML CDR from error directory again to the web server (As per doc https://freeswitch.org/confluence/display/FREESWITCH/mod_xml_cdr) In this script following curl command is doing the trick for CDR in $(find $CDRDIR -name "*.cdr.xml"); do echo "Resubmitting $(basename $CDR .cdr.xml)..." echo -n 'cdr='$(cat $CDR) | \ curl -sS -X POST -f --$AUTH_SCHEME -u $CRED -d @- $URL >/dev/null \ && echo "OK, removing CDR file" \ && rm -f $CDR done My question is how to handle the case when even this submission fails because of any reason?..I want to skip the remove file step in case again some error happens with web server, How can I do that?

Finding session variables by name pattern
by Oleg Stolyar 02 Mar '16

02 Mar '16

Hi guys, is there a way to find all the session variable with a certain name pattern *in lua*? For example I need to find all the session variables whose names start with "bla_" As an alternative is there a way to iterate over all the session variables? Then I can just do that and find the variables I need this way.

mod_sofia: Getting "sip_remove_183sdp" flag into upstream
by Sven Neuhaus 02 Mar '16

02 Mar '16

Hello, there is a patch by Artur Cichocki to add a "sip_remove_183sdp" flag that I am using. It was posted at <http://lists.freeswitch.org/pipermail/freeswitch-users/2011-June/074001.html> a while ago. I'd like to see this patch integrated into the upstream version. What's the best way to achieve this? Regards, -Sven
