Max. Number of 8 span PRI cards
by Ashish gautam 23 May '13

23 May '13

Hi, I want to ask that is it possible to use 3 eight span PRI cards on a single FS server? I mean is there any limit up to which the system performs optimally on this? Please throw some light on this. Thanks -- Ashish Gautam IVR Developer Nucleus Microsystems (Pvt.) Ltd. +91 8802865008

inband DTMF bleeding through
by Matt Broad 23 May '13

23 May '13

Hi, I have the following dialplan in my public folder (the dest_number below is just an example): <include> <extension name="dialExt1002"> <condition field="destination_number" expression="^(1234)$"> <action application="set" data="drop_dtmf=true"/> <action application="export" data="drop_dtmf=true"/>  <action application="bind_meta_app" data="4 b s execute_extension::att_xfer XML features"/> <action application="set" data="ignore_early_media=true" /> <action application="set" data="ringback=${uk-ring}"/> <action application="set" data="call_timeout=30"/> <action application="bridge" data="user/1002"/> </condition> </extension> </include> I am trying to prevent the DTMF tones from being heard by the b-leg (in this case user/1002). This works fine if the extension is called by a registered softphone (the user_context is set to public). The digits are pressed and no beeps or tones are heard by the other side. If this extension is dialed by a landline/mobile number, when a digit is pressed there is a slight "bleeding" of the DTMF. Enough to distinguish between different digits, though probably not enough to determin the digit pressed. I have tried several things such as stop_dtmf in the dialplan, setting the dtmf-duration to 0 (not quite sure what this param does but tried it anyway :) ) in the sip profile but nothing seems to prevent it. Could it be our provider? They have confirmed that they use out-of -band rfc2883. But without the drop_dtmf being set in the dialplan the full tone is heard. Could they be sending inband and out-of-band? Could anyone suggest any tests I could run or any log files I could look at please? Many Thanks Matt

SDP manipulation and sofia_glue.c (developer help)
by Daniel Ivanov 23 May '13

23 May '13

I am having difficulties forcefully stripping the a:crypto lines from the remote sdp string. At first i was doing <action application="set"><![CDATA[switch_r_sdp=$sdp]]> </action> from the diaplan, but this breaks the proxy media easily, because it doesn't patch the SDP later for glueing. I commented the following lines where the patcher is checking if the sdp string has been set before : void sofia_glue_tech_patch_sdp(private_object_t *tech_pvt) { switch_size_t len; char *p, *q, *pe, *qe; int has_video = 0, has_audio = 0, has_ip = 0; char port_buf[25] = ""; char vport_buf[25] = ""; char *new_sdp; int bad = 0; */** * if (zstr(tech_pvt->local_sdp_str)) {* * return;* * }* **/* And now i got the correct sdp sent to the b-leg(patched for proxy media and nat), but no audio is going either way. Would there be a more clever way to "rip" some lines from the SDP and not break the NAT/Proxy media processing afterwards? Help is much appreciated.

The number of registered phones
by andpe 23 May '13

23 May '13

Hi What is the possible number of registered phones to FreeSWITCH? I know it may depend on many factors. Where can I find this information? Is 2000 or 3000 users a lot or not? I'm not asking about the performance of connections here. Regards Andy

I am a newbie to FS and I want learn it. So I setup a Centos 5.2 (fresh install) and followed the instruction on the wiki installed the new Freeswitch v1.0.3. After the installation I can start FS by issus command "/usr/local/freeswitch/bin/freeswitch". After that I copied freeswitch.init.centos5 to /etc/init.d/freeswitch and chmod it to 755. Reboot the server and FS is not running. If I try the start up script: [root@localhost build]# /etc/init.d/freeswitch start Starting freeswitch: [ OK ] [root@localhost build]# /etc/init.d/freeswitch status freeswitch dead but subsys locked Did I miss somthing here?

Mod_db deleting data from database
by info＠shishir.com.np 22 May '13

22 May '13

HI I am setting up the intercept feature, and I went through the wiki on how to accomplish it. The only question I have is once I inserted data on the db with <action application="db" data="insert/realm/key/value"/> how could I delete this data out of the db ? I see the <action application="db" data="delete/realm/key"/> will delete the record, is this the only options that I have to delete the record from the db ? If yes then how could I use it to delete the record when the call gets hangup? Do I have to have this action on every calls that get hangup? Thanks in advance.

Using FreeSWITCH as a proxy
by Oleg Stolyar 22 May '13

22 May '13

Hi, I am trying to use FreeSWITCH as a SIP proxy. I have the dialplan below which simply sets bypass_media to true and then bridges to another FreeSWITCH server. However, when during the call I shut down the proxy FS, the call is immediately dropped. Why is that? Is there a way to keep it going? I understand that in this case I won't be able to properly send the BYE signal when one of the parties hangs up and that's OK. I tried using redirect and deflect instead of the bridge but those don't seem to work at all - probably because my UAs don't know how to handle redirects. <extension name="proxy_test"> <condition field="destination_number" expression="^(p\w+)$"> <action application="set" data="bypass_media=true"/> <action application="bridge" data="sofia/external/1000(a)10.2.182.243 "/> </condition> </extension>

Node.JS ESL libraries
by Alex Lake 22 May '13

22 May '13

Just beginning to get a bit more advanced with our use of Freeswitch, and we'd like to start integrating it's internal data and status with the outside world a bit more. The idea was to listen in on the event socket and use that information to update an external data model. Looking at the wiki(http://wiki.freeswitch.org/wiki/Event_Socket#Javascript_.2F_Node.js_li…, there seem to be 3 or 4 examples of how this is done, but I wondered if there's stuff that's not there or if one of these methods is proving more popular than the others. Any advice on where we should look first would be appreciated, cheers!
