Hi Michael, no, I haven't even set the parameter. So it is set to default which is false I guess. In this case it wouldn't be problem to pass this packets through. In my test setup for this case, I did not send any DTMF tones.

[Config Problem] RTP Communication to callee interrupted
by Mitja 09 Jan '14

09 Jan '14

Hey all, I have problem after upgrading to fs stable 1.2.17 (also earlier stables like 1.2.14 for that matter). The configuration Ive been using for years (more or less) shows some serious issues with a newer release. To be more precise: Sporadically but in every call FreeSWITCH does not send some RTP packets to the callee. By a network trace I can see that the RTP packets from the caller are actually received by the server. I even enabled the following lines in switch_rtp.c #define DEBUG_2833 #define RTP_DEBUG_WRITE_DELTA #define DEBUG_MISSED_SEQ But still can't see any error or clue what happened to those packets. The only thing I see, is that there is a big delta between the last send RTP packets (which is true obviously): 2014-01-08 18:39:46.258984 [ERR] switch_rtp.c:4433 WRITE 172 delta 37059 Now I did not open a jira because when I tested the same setup with a close to standard config (I just changed the dialplan and directory to suit my test setup) it all worked fine. So the conclusion is obviously that I have a configuration issue. But I have no idea where to start, so I hope maybe someone can point me in a direction. Any help is appreciated. In short: FS git-1d3417a 2011-06-07 17-35-49 [I know its old] with own config -> works fine FS 1.2.17 with own config -> RTP hickups FS 1.2.17 with default config -> works fine Regards, Mitja

Set Max-Forwards for bridged calls
by Grant Bagdasarian 09 Jan '14

09 Jan '14

Hello, I have yet to investigate why the outgoing leg when bridging an incoming leg has a very low Max-Forwards value. It always starts with Max-Forwards: 7 which causes problems. I did force the value to be 70 by setting {max_forwards=70} in the bridge application, which works great, but this means I have to do this every time I do a bridge somewhere in the dialplan. Is there a way to set this value globally so each outgoing leg takes this value for its Max-Forwards header? Perhaps in the sip_profiles, var.xml, or somewhere else? Thanks, Grant

Re: [Freeswitch-users] Issues creating/modifying FreeSWITCH files after using MSI installation in Windows 8
by Jeff Leung 09 Jan '14

I'm with Mr. Lenk on this issue here. Before you go full blast blaming people here, have you searched the wiki before you posted here? Hint: You can point Freeeswitchconsole.exe to look for the config files elsewhere. Using sc.exe, you can alter the argument to have it looking to your desired location. -------- Original message -------- From: Jeff Lenk <jeff(a)jefflenk.com> Date: 01-08-2014 4:42 PM (GMT-08:00) To: FreeSWITCH Users Help <freeswitch-users(a)lists.freeswitch.org> Subject: Re: [Freeswitch-users] Issues creating/modifying FreeSWITCH files after using MSI installation in Windows 8 Your tone is kinda disrespectful here! I have provided an msi as an example of many things that FreeSWITCH can do and do so without having to build the code. It is a very simple MSI and I would like individuals perhaps like yourself to help out and contribute patches to enhance the installer. Nothing undocumented about it the permissions aren't set to allow files to be created or modified unless you are the administrator. Your point about default permissions here is fair enough and I would consider modifying that. It would have been far better suited for you to offer to patch the MSI building process to set some default permissions.

Specifically, it seems that I can't seem to create OR modify files in the FreeSWITCH directory located (by force) in Program Files. Before you ask, yes-I'm using the 64-bit MSI/version in a 64-bit OS. For instance, when I right-click in any folder in the FreeSWITCH directory tree and go down to "New", this is what I see: <http://i.imgur.com/1IJfir4.png>. When I try to edit an existing file, I'm told that it's "read only" and my changes can't be saved. How nice. Interestingly enough it seems that only sub-folders located in "Program Files" or "Program Files (x86)" exhibit this level folder/file protection, and I am a member of the local "Administrators" group. Having a bit of experience with all version of Windows post-Vista, I suspect that some craptastic (un?)documented feature of UAC is "protecting" the contents of the FreeSWITCH directory...just like it protects the rest of the contents of Program Files as well. Now to my point: as anyone who has ANY degree of experience with Windows in the last 10 years fully knows, there are virtually NO PROGRAMS in existence that store configuration data actually IN the Program Files directory, or a sub-directory therein....so why in tarnation does FreeSWITCH?!? Please fix this, or if I'm missing some really obvious solution to this problem, please-enlighten me in a response. If you're going to suggest that I simply move the folder out of the Program Files directory to somewhere else on the system that isn't "protected" by UAC, that's a GREAT idea! I think I'll do JUST THAT. But why should I have to in the first place??? For that matter, why doesn't the MSI installer give you the option of installing the program somewhere OTHER than Program Files??? Food for thought...

Handling unavailble destinations
by Grant Bagdasarian 09 Jan '14

09 Jan '14

Hello, Consider the following scenario: Carrier ------------ SBC1 ------------ PROXY1 ------------ DESTINATION1/DESTINATION2 The carrier sends an incoming call to our SBC (SBC1). The SBC bridges the incoming leg with an outgoing leg towards the Proxy (PROXY1). But it does not answer the incoming leg, it stays in an early state until the call is answered down the road. The Proxy(Kamailio) tries to contact DESTINATION1 OR DESTINATION2 by distributing the traffic round-robin style. Let's say the first destination is not available. The proxy will then try to contact Destination2 after its timeout triggers. This works fine. Our carrier has its own timeout. If we don't connect the call in time, they cancel the current request and send a new one to the fallback IP. What I want is the following: have the SBC1 tell the carrier for the incoming leg that we are trying to connect the call by perhaps sending provisional messages every X interval. And have the proxy control which destination is available. If both destinations are unavailable, the proxy should respond with a failure message which is sent back to the incoming leg by the SBC. Normally if a destination is available I use <action application="set" data="bridge_early_media=true" /> to send the provisional messages from the outgoing leg back to the incoming leg. But when the destination is not available, no responses received, the carrier cancels the call when their timeout occurs. Am I making any sense? Is it possible to accomplish this?

Multiple m-lines
by Stephen Wilde 08 Jan '14

08 Jan '14

On of my providers cannot handle INVITEs with 2 m-lines but in some cases, probably depending on what receives, my Freeswitch sends an INVITE with 2 m audio lines, one for ptime=10ms and one for ptime=20ms. Attached a screenshot. I have added the following line in dialplan: <action application="export" data="sdp_m_per_ptime=false" /> without success. Any suggestion? Stephen [image: Inline image 1]

multiple registration + number-alias
by tilt 08 Jan '14

08 Jan '14

Hello all, I am trying to utilize number-alias and ring multiple registrations to the same endpoint. So far I have the multiple endpoints ringing, but I cant find a way to incorporate the number-alias into the dialplan xml "Local_Extension" The below works for the multiple endpoint ringing per single registration/user (http://wiki.freeswitch.org/wiki/Sofia-SIP#Multiple_Registrations) <action application="bridge" data="${sofia_contact(${dialed_extension}@${domain_name})}"/> *Problem*: How can I also incorporate the number-alias feature, so that both features work? Here is the example in wiki (http://wiki.freeswitch.org/wiki/XML_User_Directory_Guide#Alphanumeric_to_nu…) <action application="bridge" data="user/${user_data(${destination_number}@${domain_name} attr id)}"/> Any help would be much appreciated. Thanks, John

Recording during a failover recovery
by Brian Fertig 08 Jan '14

08 Jan '14

Greetings, I am working on a scenario where a leg of a call is being recorded. In the event of a failover recovery the recording persists which is great. During testing I found that when the failover takes place the failover FS server overwrites the recording originally created by the original FS server. Is there a way to cause the failover server to append to the recording and not overwrite it?

Freeswitch + TLS with a commercial certificate
by Iskren Hadzhinedev 08 Jan '14

08 Jan '14

Greetings. I'm unable to setup TLS and SRTP. I have a valid certificate from GlobalSign and my setup is currently the following: My certificate and key (merged with cat keyfile certfile > agent.pem) in /opt/freeswitch/conf/ssl/agent.pem The GlobalSign root certificate is in /opt/freeswitch/conf/ssl/cafile.pem I edited vars.xml as instructed from http://wiki.freeswitch.org/wiki/SIP_TLS#Configuration I tried running with tlsv1 and sslv23 in vars.xml, verified that FS is listening on ports 5061 and 5081 with netstat -nltp | grep freeswitch Also I get TLS listeners with "sofia status" so it should be working. Connecting to ports 5061 and 5081 with openssl s_client connect freeswitch.lan:<port> is successful, but I get a 'Verify return code: 21 (unable to verify the first certificate)'. Running nginx with the agent.pem as a certificate is working without any issues. When I try to connect to Freeswitch via TLS with Bria and Linphone 3.6.1 I get errors 408 or 503 and I don't see any output into the freeswitch console where I enabled sofia siptrace globally. What is the correct way to setup Freeswitch with a commercial certificate in order to enable TLS and SRTP ? Thank you!
