Problem with Cancel
by kawarod 09 Jun '11

09 Jun '11

Hi List, I have an issue with FS connected to a SIP gateway. When I receive a call from the SIP Gateway and try to hangup the call before he call is answered, so that a Cancel is emitted by the SIP GW, I have a SIP 481 Call Transaction does not exist. I understand that FS is unable to match this Cancel with the correct Invite, so that FS can not process the Cancel. Below is the SIP trace. It seems to me that the issue is because the Invite and the Cancel (generated by the same SIP GW) have different branch in the Via field. But I have no way to update the SIP GW and I absolutely need it for connection to the core network. May you please help to check if the issue could be related to the Via branch. It seems that they should be the same based on RFC. Do you have any idea to bypass this issue (any SIP profile magic trick :p). I made a "make current" this morning to check if this could help.

Conceptual/design question - per gateway/DTMF & PSQL
by Mike Taylor 09 Jun '11

09 Jun '11

Hi, I hope that I've taught myself enough over the last few weeks that this isn't a blindingly stupid question I am providing services to multiple customers on FS 1.0.6 I have a basic setup; (which I have inherited, hence the basic questions); AS5350--------<external>----- FS-----<internal>------customer GW(s) (No Registration) (No Registration) All of the GW info is pulled from a PSWL database. Carriers, carrier_id, lcr table etc. The bit I am missing is; If all of my GW config is in the PSQL database, and that's all accessed by mod_lcr before routing the call, how do I allow for different DTMF types, codecs etc, PER CUSTOMER GW ? Am I stuck with actually defining the gateways statically under /etc/freeswitch/conf/sip_profiles/ (or I see I can doit in the dialplan, but that won't achieve what I need) I was hoping to be able to pull the DTMF (and other misc info) from the database, but the more I look into it, the less likely it is that this will work I think. (mod_lcr is already at the routing stage, can't modify DTMF at that point AFAIK) Like I said, hope the question isn't so obvious that it's crazy Regards, Mike

Setup help Conference, 3 way call, FIFO, MOH, record to Shoutcast
by Rev Michael Carbone 09 Jun '11

09 Jun '11

I have things setup and working and am using fusionpbx and am totally new to all this. I am setting things up to have an online call in talk show. What I want to be able to do is this: Have me and a guest on and the call broadcasting to a shoutcast/icecast server (which I have already) and want to be able to broadcast this as MOH, how can I also have people in a FIFO cue listening in on the show and be able to bring them in one at a time. Broken down: 2 of us on a call broadcasting to shoutcast other people call in and are put in cue with conversation as MOH bring people on air one at a time while others are still muted I'm sure this can be done, but how? Please remember I'm new to all this so instructions would be helpful. Thank you, Michael

Problem receiving calls from E1 to TE122p
by Javier Galaz Jeria 08 Jun '11

08 Jun '11

Hi, I'm using FS git, on Ubuntu 11.04, with Digium TE122p card (from now on srv1), and FS git, on Ubuntu Server 11.04 with Sangoma A101 card (from now on srv2), both currently configured by vendor's scripts. When I make a call from srv1 to srv2, everything goes well, I can hear both ways no problem, however when I try it the other way around (srv2->srv1) the softphone registered to srv2 gets "User Not Available", hardphone registered to srv1 gets INVITE and just after that CANCEL. The FS log: [1] Looking at the logs I can see that after the RINGING goes to EARLY and tries to play ringback tone, but it can't write and it can't read from channel because it's not opened. So it hangs up. [lines 520-528] I've searched the wiki, asked on IRC, but can't solve my problem, anyone who has configured TE122p could give some pointers? This are my config files: -----TE122p----- /etc/dahdi/system.conf loadzone = es defaultzone = es span=1,1,0,ccs,hdb3 bchan=1-15,17-31 dchan=16 echocanceller=mg2,1-15,17-31 /usr/local/freeswitch/conf/freetdm.conf [general] cpu_monitor => no cpu_monitoring_interval => 1000 cpu_set_alarm_threshold => 80 cpu_reset_alarm_threshold => 70 cpu_alarm_action => warn [span zt TE122p] trunk_type => E1 b-channel => 1-15 d-channel => 16 b-channel => 17-31 /usr/local/freswitch/conf/freetdm.conf.xml <configuration name="freetdm.conf" description="FreeTDM Configuration"> <settings> <param name="debug" value="0"/> <param name="sip_headers" value="true"/> </settings> <libpri_spans> <span name="TE122p"> <param name="node" value="network"/> <param name="switch" value="euroisdn"/> <param name="dialplan" value="XML"/> <param name="context" value="default"/> </span> </libpri_spans> </configuration> ------A101----- /etc/wanpipe1.conf [devices] wanpipe1 = WAN_AFT_TE1, Comment [interfaces] w1g1 = wanpipe1, , TDM_VOICE_API, Comment [wanpipe1] CARD_TYPE = AFT S514CPU = A CommPort = PRI AUTO_PCISLOT = NO PCISLOT = 4 PCIBUS = 2 FE_MEDIA = E1 FE_LCODE = HDB3 FE_FRAME = NCRC4 FE_LINE = 1 TE_CLOCK = NORMAL TE_REF_CLOCK = 0 TE_SIG_MODE = CCS TE_HIGHIMPEDANCE = NO TE_RX_SLEVEL = 430 LBO = 120OH FE_TXTRISTATE = NO MTU = 1500 UDPPORT = 9000 TTL = 255 IGNORE_FRONT_END = NO TDMV_SPAN = 1 TDMV_DCHAN = 16 TE_AIS_MAINTENANCE = NO #NO: defualt YES: Start port in AIS Blue Alarm and keep line down #wanpipemon -i w1g1 -c Ttx_ais_off to disable AIS maintenance mode #wanpipemon -i w1g1 -c Ttx_ais_on to enable AIS maintenance mode TDMV_HW_DTMF = YES # YES: receive dtmf events from hardware TDMV_HW_FAX_DETECT = NO # YES: receive fax 1100hz events from hardware HWEC_OPERATION_MODE = OCT_NORMAL # OCT_NORMAL: echo cancelation enabled with nlp (default) # OCT_SPEECH: improves software tone detection by disabling NLP (echo possible) # OCT_NO_ECHO:disables echo cancelation but allows VQE/tone functions.
