Would anyone be willing to port the Aastra XML scripts for Asterisk to FreeSWITCH? I would be willing to sponser.

B Leg on bridged call is not hanging up
by Nik Middleton 04 Dec '09

04 Dec '09

Hi Guys, This one has me stumped. I'm originating a call, playing audio, trapping on DTMF and bridging to another endpoint (read phone number) If the A leg hangs up, then the call is cleared down and all is well. However if the B Leg attempts to hang-up, the LUA script that is handling the bridge continues to play audio to the a leg, while the B leg is in limbo. It does eventually time out with no RTP. Running Sofia debug on the cli shows that I'm getting the BYE from the B Leg, but that's about as far as I can get. The hang-up hook is not being fired in the lua script. Anyone give me some pointers as to where I might start looking? regards

Re: [Freeswitch-users] Lua and database access to core_db
by Jon Bruel 04 Dec '09

04 Dec '09

I have now tested the FS with core db configured using MySql (by modifying the switch.conf.xml file). Unfortunately, it does not solve my problem because some of the core tables still remain as active SQLite tables. After restarting the FS in the new configuration (with SQLite database core deleted), the following tables are created in MySql and SQLite: MySQL: aliases, complete, nat and tasks (database starting with no tables prior to FS restart). SQLite: aliases, calls, channels, interfaces, nat and tasks. As I would like to access the channels table using Lua, the change did not fix my problem. I have positive verified that the channels table is active and populated during calls. Are there other places where I should define the usage of the MySql database?

HA questions.
by Tim Uckun 04 Dec '09

04 Dec '09

I have read some of the archived emails about HA, loadbalancing, failover etc and I am still a bit confused about how I could set up some sort of resiliency with freeswitch. My situation is much less complex than the scenarios people were talking about and I hoping the solution is similarly much less complex. I have two machines. Both will run freeswitch and also an IVR application with local databases. I will take care of the database, application and configuration synchronization between the two machines. Ideally the calls would be load balanced between the machines and if any application falls down then the calls should go to the other machine. Same if I take a machine down for whatever reason. If a machine goes down I am willing to "lose" those people who were making a call at the time. I do have a flag in the application which will stop answering the calls while processing the existing calls for a graceful shutdown and hopefully the load balancer would shuttle the calls to the other machine while this is happening. At this stage everything is done via SIP. My questions are... Do I have to have a sip proxy? If the answer is yes it seems like I have to set up two sip proxies so I don't have another single point of failure. Can I load the sip proxies on the same machine? Do I need two more machines? If I take load balancing out of the picture would it be possible to do a simple linux HA or a windows built in ip failover solution? Would a simple IP failover work over UDP or would I have to use IAX and tcp/ip ? Is it better to go the virtualization route? Sorry if these are dumb questions. I am just trying to get my head wrapped around this. I don't need five nines (although that would be awesome), I just want a reasonable degree of assurance that my app can keep taking calls in case something weird happens.

IAX? Issues connecting road warriors with SIP?
by Fred-145 04 Dec '09

04 Dec '09

Hello In a thread back in March, I read that support for IAX in FreeSwitch is a bit of kludge and since there's not much demand for it, chances are it won't improve in the foreseeable future. So I'd like some feedback from users who routinely connect to a FreeSwitch server from various venues, ie. wifi hotspots at McD, Ethernet LAN in hotels, etc. (in my case, the FreeSwitch server is located in a private network behind a NAT router with SIP/RTP ports statically mapped.) Do you sometimes/often get issues where SIP (UDP5060) or RTP (UDPwhatever) ports fail being opened dynamically to work properly, or does SIP today really work well over NAT firewalls? Thank you. -- View this message in context: http://old.nabble.com/IAX--Issues-connecting-road-warriors-with-SIP--tp2662… Sent from the Freeswitch-users mailing list archive at Nabble.com.

Re: [Freeswitch-users] Lua and database access to core_db
by Jon Bruel 04 Dec '09

Anthony, you advised me to use MySQL as the core database in order to access it from Lua. I'm testing that as a work-around. Still, I guess that your choice of SQLite as the default core database have been taken from efficiency or stability considerations. Using MySQL through an ODBC-connector does not sound as a clean solution. Have you any experience about "how bad" it is to use the ODBC MySQL combination in terms of stability, memory leaks and efficiency?

record mp3s
by Neil Patel 04 Dec '09

04 Dec '09

Hi All, This is a great list, thanks for all of the support! For my IVR app running on FS, we we accept potentially long audio recordings. Is it possible (in lua) to save recorded as mp3? Thanks, Neil

Cisco IOS gateway: command to send connected line name
by Yehavi Bourvine 04 Dec '09

04 Dec '09

Hello, We have a Cisco running IOS 12.4T used as our SIP-PRI gateway. On the PRI there is a Nortel with Q.Sig. After a lot of configuration trials I've managed to set it to send back the connected name over the SIP (i.e. when a call goes from SIP to PRI, the PRI sends back the connected name and then the Cisco adds it as a Remote-Party-ID). However, I did not save it and a power outage cleared this config. In my age I don't remember what I've done... Anyone knows the correct config? Thanks! __Yehavi:

Cannot Do this Basic thing
by Samuel Abekah-Mensah 04 Dec '09

04 Dec '09

I have copied 1001.xml in directory/default to a test user 2319.xm changing or instances of 1001 in the file to 2319. I then went into default.xml in directory folder and in one of the groups just mimicked 1001 details by changing 1001 to 2319. Connecting to FS gives Forbidden message. However 1001 connects without a problem. What have I missed ? Is there a place that just puts things in do this and that and that to create a new user ? Thanks
