Doubts over G729 passthru for 50ms ptimes
by Ben N 29 Nov '12

29 Nov '12

Hi All, I'm wondering if anyone out there is using G729 with 50ms ptime through Freeswitch, without proxy media? I am unable to get this to work, even in a very basic lab with just two clients and an up to date FS server on the same LAN. I can get G729 with 20ms working, but 50ms causes Freeswitch to hang the call. It might be that mod_g729 and mod_com_g729 simply don't support it, so if anyone in the know can tell me that would be great! Further info can be supplied, I believe I have tried pretty much all options.... Cheers, Ben

Sofia listens only on 127.0.0.1 after server VM reboot?
by Dmitry Sytchev 29 Nov '12

29 Nov '12

Hi All! We faced strange problem after FS migration from hardware server to Debian 6.0.6 in VMWare ESXi. After every VM reboot, FS starts normally, but doesn't receive any SIP traffic. netstat -ln shows that freeswitch listens on *:5060, but if we do 'sofia profile local restart', it says than it restarts on 127.0.0.1 If we do /etc/init.d/freeswitch restart, FS starts normally and work as expected. My only idea is that probably FS starts earlier than network interfaces become configured with IP, although there is $network in # Required-Start section of init script. Nothing changes if I set $all in #Required-Start to make FS start at the very end of boot. I tried to configure static IP in config instead of $local_ipv4, but with no luck. Probably if the problem is in unconfigured IP interface, we also need enable_nonlocal_bind proc settings to make this work, but it is a generally poor and inacceptable workaround :( Any ideas how can I trace what is the exact problem leading to such behaviour? -- Best regards, Dmitry Sytchev, IT Engineer

FreeSwitch on a VM?
by Steven Schoch 29 Nov '12

29 Nov '12

In setting up a PBX to run FreeSwitch, I have allocated a machine that is overpowered, so the best use of this resource is to put a hypervisor such as Xen on it, and make it available for other office uses. Is there any reason why running FreeSwitch on a VM is a bad idea? -- Steve

Re: [Freeswitch-users] FreeSWITCH-users Digest, Vol 77, Issue 196

with respect to running FS on a VM, one thing that has not been mentioned is the need for a real time kernel in the underlying host. This can be a big issue when running on a hosted vm in the cloud, as typically you will not have a choice of kernel, nor the ability to recompile. I have had bad experience with several hosting companies claiming to run 10msec kernels, but in reality running 25 or even 100 msec versions - lot of potential for dropped and out of order speech with the later. packetandy

About the "transfer" function
by sparklezou 29 Nov '12

29 Nov '12

Hi All, When dial an internal number "1234", it will "bridge" or "transfer" to an external number "87654321". And on the caller phone will disply "Outbound Call", also show the number "87654321". I checked the sip message, the info is got from the 180 or 183 message. Sometime, don't want to show the real external number "87654321" to the enduser. How to keep the caller phone displaying "1234". Thanks in advance! 2012-11-28 sparklezou

SIP to TDM t38 gateway
by Spencer Thomason 29 Nov '12

29 Nov '12

Hello, I'm trying to use Freeswitch as a SIP to TDM gateway. I'd like to use t38_gateway to detect fax tones and send a ReINVITE to t38. Have a very minimal config with one profile that simply relays to FreeTDM My dialplan is: <include> <context name="sip"> <extension name="dial-trunk"> <condition field="destination_number" expression="^(.*)$"> <action application="set" data="fax_enable_t38=true"/> <action application="set" data="fax_enable_t38_request=true"/> <action application="set" data="execute_on_answer=t38_gateway self"/> <action application="bridge" data="freetdm/1/a/$1"/> </condition> </extension> </context> </include> The problem is a media bug is created on the channel but almost immediately destroyed so fax tones are never detected. See: http://pastebin.freeswitch.org/20162 Thanks for any assistance, Spencer

[Confidential] - uuid_broadcast
by Nuwan Wijerathne 28 Nov '12

28 Nov '12

Hello All, I'm resending this request as I haven't had any reply for my last two emails. If anyone know any information regarding this, please let me know. . Any help would be greatly appreciated I'm trying to broadcast audio on a bridged call. My requirement is to play audio on both legs at the same time. I used uuid_broadcast in following order, uuid_broadcast uuid 'path' both Please note that I'm sending uuid_broadcast through an esl connection. So my actual request to freeswitch is as follows, eslWriteConnection.Send("bgapi uuid_broadcast uuid 'path to audio file' both"); (eslWriteConnection is an object of .Net ESLConnection) The issue I'm having is, freeswitch not playing the audio on both channels at the same time. FreeSwitch plays the audio on one leg first, then plays on the second leg (After it finished playing on first leg). I don't have this issue with FreeSwitch 1.0.6, where it plays audio on both legs at the same time. I'm having this issue with FreeSwtich 1.2.3 and later versions. Could anyone please suggest any solution. Thank you, This e-mail and any attachments are for the intended addressee(s) only and may contain confidential and/or privileged material.
