by Bilal Abbasi 02 Aug '16

02 Aug '16

Hi Users, I am getting some weird error on Freeswitch, that is coming on calling random extensions, I have a dialplan for 3 digit extensions , so when i can 194 it works perfect and when i call 197 it gaves me below error, Duplicate UUID! unable to create channel. What i have in my dial plan is, <action application="set" data="b-leg-uuid=${create_uuid()}"/> <action application="bridge" data="{origination_uuid=${b-leg-uuid},api_on_answer='uuid_audio ${b-leg-uuid} start write mute -4'}user/${destination_number}@ ${domain_name}"/> Can someone please guide me what i am doing wrong in this, P.S: some times calling 197 works perfect and it comes on 194 WEIRD. Regards Bilal Abbasi

play_and_get_digits questions
by Anonim Stefan 02 Aug '16

02 Aug '16

Hi, While in a group call, I'm using "play_and_get_digits" to dial out a number as shown in example [1], triggered via a DTMF key: "<control action="execute_application" digits="*1" data="execute_extension ASK_FOR_NUMBER_447279569204 XML default"/>" The issues I'm facing is that when the user forms the number, DTMF caller controls get triggered(like mute, vol up, etc..) as defined in conference.conf.xml. 1. Is there a way to not trigger those DTMF caller controls while forming the number when using play_and_get_digits? 2. Is there a way to get some details in the ASK_FOR_NUMBER_(\d+) extension, about the one that triggered the DTMF? (i.e. something like user_name or user_number) Thanks, Stefan [1] https://wiki.freeswitch.org/wiki/Conference_Add_Call_Example

save voicemail via http
by jungle Boogie 02 Aug '16

02 Aug '16

Hi All, Has anyone successfully saved voicemail off of their freeswitch install using http? I know you can mount a nfs share and save the files the share. Is that what people usually do? If not, how do folks make voicemail accessible when using a backup freeswitch server? Is something like couchDB used? Does the voicemail code support http put/post methods? Thanks! -- ------- inum: 883510009027723 sip: jungleboogie(a)sip2sip.info

How to change default text in hangup SIP messages? For example I want hangup with "503 Call limit exceeded" instead of just "503 Service unavailable" for call limit.

rtcp-mux on B-leg but there is no signaling in SDP
by Richard Chan 02 Aug '16

02 Aug '16

Hi list, FreeSWITCH 1.6.9 and the default configurations: FreeSWITHCH is using rtcp-mux on the B-leg without signalling in SDP (i.e. no rtcp-mux attribute). If I change rtcp_audio_interval_msec to passthru or say 2000 then there is explicit rtcp-mux in the INVITE SDP. The UAC I'm using, sends a few packets to RTP+1, FreeSWITCH sends RTCP with source port the same as RTP, and the UAC auto-adjusts after 10 or so packets. This UAC always includes an a=rtcp line even if the RTCP port is RTP+1. Is this a "bug"? I would expect FreeSWITCH to signal rtcp-mux on the B-leg. (On the A-leg, FreeSWITCH doesn't use rtcp-mux and includes an explicit rtcp port in SDP). -- Richard Chan

The delay is quite random between one and 4 seconds. I already played around with group_confirm_read_timeout and replaced the prompt with a shorter version because initially I thought it was always continuing to play the prompt to it's end before proceeding but that's not true. Any tips and/or is this worth filing a bug? Thx in advance Benedikt

How to detect North America RING_TONE using spandsp
by Naveen Tamanam 01 Aug '16

01 Aug '16

Hi, I'm trying to detect North America RING_TONE using spandsp Using default settings as mentioned follows <tone name="RING_TONE" description="North America ring"> <element freq1="440" freq2="480" min="1200" max="0"/> </tone> But I'm not getting consistent tone detections. Is there any thing that I need to change to have a proper tone detection. As per the tone/spectrum analysis using audacity. This tone is having two frequencies 440 and 480 a mentioned in conf, but spandsp is not detecting them. To have a proper and consistent tone detection how much duration I should use? Please refer spectrum analysis of tone representing 440Hz & 480Hz frequencies. As per the doc min and max values represents duration. How to determine these durations of any give tone? What is the meaning of having max value 0 ? -- Thanks & Regards, Naveen Tamanam
