launch an external program in dialplan
by Gilles SAUVAIRE 10 Aug '22

10 Aug '22

Hi there, I need inside a dialplan, to launch an external program, and to take the return of this program to use it in the dialplan. I think a LUA script can do it? If anyone has an example script, I'm interested. Or is another technique better? Launching an external program at each call can be very resource-intensive, maybe make a request on a specific web service port, or something else? the idea is to add the user's name in the from. (but this name changes depending on the external context, it must be calculated, I cannot make a simple database query) someone has already done it I guess I'm not the first to have this need... Thank you all... Gilles

freeswitch 180 ringing retransmission interval update
by Patrick Karton 09 Aug '22

09 Aug '22

when b leg is in ringing state freeswitch retransmits 180 on a leg every 60 seconds even if b leg does not send 180. is there a param to increase that interval ? Thanks.

problem with Grandstream FXO gateway
by Jason Holden 09 Aug '22

09 Aug '22

All, Any suggestions on the following? We have a Grandstream FXO gateway where a call is sent to and I receive a 180 rinigng followed by a 200ok message but the line plays back an audio busy message. Any ideas how to force a fail over / continueation in the dial plan in this situation?

Spurious DTMF characters when using RFC2833 with SRTP
by Andy Newlands 04 Aug '22

04 Aug '22

Hi, We have a reproducible problem where spurious DTMF characters are introduced on calls from Freeswitch to a remote (3rd party) IVR, but ONLY when using SRTP (not with RTP) When the spurious character is generated it is: 1. Only ever following a valid/legitimate character (one that was genuinely keyed) 2. Often has a very long duration (see below) 3. Appears to be a random character - often 0x00, but sometimes 0-9/A-F,#,* (and that's when we get problems with the IVR - FS automatically drops the 0x00 values). We have been able to reproduce this from mobile/cell phones and traditional land-lines. I added some code to: switch_rtp.c, in static handle_rfc2833_result_t handle_rfc2833(switch_rtp_t *rtp_session, switch_size_t bytes, int *do_cng), to try to address this. It logs an error (with the character hex value and duration) for DTMF characters with "long" durations (over 10000) and then discards them. As you can see, below, this is a fairly frequent occurrence (although most of the time, the character value is null, so FS drps it, anyway - but sometimes, "real" characters are introduced). 2022-02-28 14:00:53.743665 [NOTICE] switch_vpx.c:599 VPX encoder reset (WxH/BW) from 0x0/0 to 352x288/1024 2022-02-28 14:00:56.103665 [INFO] switch_channel.c:522 RECV DTMF 4:2400 2022-02-28 14:00:56.303664 [ERR] switch_channel.c:557 Ignored invalid DTMF on Call-ID: 3b5d08d3-d898-40b6-ae00-5886713ca6dd, DTMF: 0x0 Duration: 5063 2022-02-28 14:00:56.383661 [INFO] switch_channel.c:522 RECV DTMF 4:2400 2022-02-28 14:00:56.583665 [INFO] switch_channel.c:522 RECV DTMF 5:2400 2022-02-28 14:00:57.063662 [INFO] switch_channel.c:522 RECV DTMF 5:2400 2022-02-28 14:00:57.123670 [INFO] switch_channel.c:522 RECV DTMF 8:2720 2022-02-28 14:00:57.323673 [ERR] switch_rtp.c:686 Discarded long-duration DTMF on Call-ID: 3b5d08d3-d898-40b6-ae00-5886713ca6dd, DTMF: 0x0 Duration: 54088 2022-02-28 14:00:57.603671 [INFO] switch_channel.c:522 RECV DTMF 9:2400 2022-02-28 14:00:57.824102 [INFO] switch_channel.c:522 RECV DTMF 8:2720 2022-02-28 14:00:57.903663 [ERR] switch_rtp.c:686 Discarded long-duration DTMF on Call-ID: 3b5d08d3-d898-40b6-ae00-5886713ca6dd, DTMF: 0x0 Duration: 57002 2022-02-28 14:00:58.183668 [INFO] switch_channel.c:522 RECV DTMF 6:2400 2022-02-28 14:00:58.363666 [ERR] switch_rtp.c:686 Discarded long-duration DTMF on Call-ID: 3b5d08d3-d898-40b6-ae00-5886713ca6dd, DTMF: 0x35 Duration: 57073 2022-02-28 14:00:58.503667 [INFO] switch_channel.c:522 RECV DTMF 9:2400 2022-02-28 14:00:58.643667 [INFO] switch_channel.c:522 RECV DTMF 1:2400 2022-02-28 14:00:58.963663 [INFO] switch_channel.c:522 RECV DTMF 6:2400 2022-02-28 14:00:59.283665 [INFO] switch_channel.c:522 RECV DTMF 1:2400 The first spurious character is 0x00 (which FS will drop anyway) but this could easily be a valid character (and would escape detection because its duration is not too long - it's long but not unreasonable). So, this is an imperfect "fix" as we occasionally see a spurious character with a legitimate value and a "sensible" duration - sufficiently often for users to complain. The last [ERR] entry shows a '5' being introduced but this is dropped because the duration is "crazy" (57073) As mentioned, this does not happen with secure media disabled - only with SRTP. So, I am wondering if the code correctly processes a digit then, sometimes (somehow) incorrectly attempts to decode part of an audio packet as though it were RFC2833. Has anyone else experienced this? Does anyone know what may be causing the problem and what the fix might be. I can provide console output and tcp dumps if required, along with any other details that may help (I'm also comfortable making code changes - to for extra logging/diagnostics etc). Thank you. Kind regards, Andy

Just client (zoiper) freezes and does nothing. I suspect this might be a client issue, maybe nothing to do with freeswitch. * (the real problem I am trying to investigate) outgoing PSTN calls work fine. But incoming calls from our VOIP provider - there is a 10+ second delay on all incoming audio, and I can't see any reason for this. i.e. I mean I say something on remote end, wait 10 seconds, then it is received at local end. * Turning on echo cancellation on a Linux based host running zoiper seemed to cut out audio after about 1 second. So I disabled that option, seems to have fixed that problem. Any ideas? -- Brian May <brian(a)linuxpenguins.xyz> https://linuxpenguins.xyz/brian/
