Codec renegotiation
by Gregor Nanger 11 Jan '18

11 Jan '18

Hi Guys! Have one question. I want to bridge call to gateway and if I get 503, bridge to another gateway. This works as expected and have no problem. But have question if I can renogotiate codecs from a leg to b when send call to another provider? Is this just matter of absolute_codec_string variable in bridge for b leg? Best regards, Gregor

Audio distorted when Negotiation of codecs on Re-Invite (G711->G722)
by José Lopes 11 Jan '18

11 Jan '18

Hello, I have an issue with audio distorted during a call when there is a reinvite that change the audio codec from G711 to G722. The issue seems to be caused by G722 which have a diferent sample rate (16000Hz) than G711 (8000Hz). I have already reported this issue at https://freeswitch.org/jira/browse/FS-10779 . I notice that this is a complex situation, so I want to ask if there is any workarround to this situation? I need to use G722 because I need to have HD voice calls. Thanks in advance for the attention. Best regards, Jose Lopes

Wrong jitter in the RECV_RTCP_MESSAGE event
by Alexander Haugg 11 Jan '18

11 Jan '18

Hi, Codec = PCMU Wireshark RTP analyse: Jitter in the Wireshark max=2,9 ms; mean=0,57 But the last RECV_RTCP_MESSAGE event show this: ========================================== SSRC: 0eb0e841 NTP-Most-Significant-Word: 3724642770 NTP-Least-Significant-Word: 4165677056 RTP-Timestamp: 14487886 Sender-Packet-Count: 1409 Octect-Packet-Count: 225440 Last-RTP-Timestamp: 14487924 RTP-Rate: 8000 Capture-Time: 1515653966925374 Source0-SSRC: 7c1b0ae5 Source0-Fraction: 0 Source0-Lost: 0 Source0-Loss-Avg: 0 Source0-Highest-Sequence-Number-Received: 32561 Source0-Jitter: 159 Source0-LSR: 2311973851 Source0-DLSR: 63014 And the last RTCP event from the Wireshark show this: ============================================= Real-time Transport Control Protocol (Sender Report) 10.. .... = Version: RFC 1889 Version (2) ..0. .... = Padding: False ...0 0001 = Reception report count: 1 Packet type: Sender Report (200) Length: 12 (52 bytes) Sender SSRC: 0x0eb0e841 (246474817) Timestamp, MSW: 3511979744 (0xd1548ee0) Timestamp, LSW: 2709503779 (0xa17fbf23) [MSW and LSW as NTP timestamp: Apr 16, 2011 21:55:44.630855000 UTC] RTP timestamp: 3435008682 Sender's packet count: 3257276450 Sender's octet count: 4258211364 Source 1 Identifier: 0x463e7aa2 (1178499746) SSRC contents Fraction lost: 248 / 256 Cumulative number of packets lost: 1105247 Extended highest sequence number received: 1972857173 Interarrival jitter: 1013423106 Last SR timestamp: 1007735790 (0x3c10d3ee) Delay since last SR timestamp: 108449976 (1654815 milliseconds) [RTCP frame length check: OK - 52 bytes] 1. What is the formula to get the jitter in ms from the rtcp? I can’t find anything in the web, or I can’t recognise the answer. 2. What is wrong, the RECV_RTCP_MESSAGE event or the RTCP from the receiver? If I have the answer to the first question, i can answer the second question by my self ;-) Thanks a lot!!! By the way, it is the newest FreeSwitch from yesterday.

record_session recordings out of sync
by Mircea BH 11 Jan '18

11 Jan '18

Hello everyone, Happy new year. I have a new freeswitch production version 1.6 installed on Debian 8, 64bits. I have just two sip phones registered and one gateway (Alcatel oxo). All are on the same switch, in different vlans. I use record_session to record calls automatically. The recordings are fine for calls between the two sip phones, but the ones between sip phone and Alcatel gateway are all out of sync. I is the same regardless of settings (stereo, mono, jitterbuffer activated). Did someone had this issue and found a solution? Thank you. Best regards, Mircea.

Odd situation bridge
by Raimundo Pérez Nieves 10 Jan '18

10 Jan '18

Hi, I have this situation: 1) Leg A calls Leg B 2) Leg B answers 3) Start exchange media but here is the problem: a) Leg B starts with silence and after that starts ringtone (but understand you are inside a bridge) The question: How can I bridge A with B only when I receive from Leg B the inside ringtone (when it answered). Consider in this situation -When Leg B answers it produces silence and after that ringtone and after that the person from the other side- . Thanks a lot

Iam not able to solve the issue with bridge_pre_execute_bleg_app. The problem I am having is that the call is answered, is in 200 OK, and is exchanging media, but there is silence before ringtone starts.

Problem with bridge_pre_execute_bleg_app
by Raimundo Pérez Nieves 09 Jan '18

09 Jan '18

Hi, The reason I am trying to use bridge_pre_execute_bleg_app is when I call from Leg A to Leg B, Leg B answers but there is a silence before ringtone. I tried ignore early media, everything, but nothing works. What I need to do is to bridge the call only when Leg B starts ringtone, I have to ignore the silence when Leg B already answer, It is a channel with many problems, that is why we want that Leg A doesn’t hear the silence. Thanks

You can define the codecs for each individual user. You can edit /usr/local/freeswitch/conf/directory/default/*.xml and define different codecs for each one user. -giovanni -- Sincerely, Giovanni Maruzzelli OpenTelecom.IT cell: +39 347 266 56 18
