Hi everyone, I am trying to send SMS via python script but not working, I followed the script in confluence from ESL import * con = ESLconnection("127.0.0.1", "8021", "ClueCon") if con.connected(): event = ESLevent("CUSTOM", "SMS::SEND_MESSAGE") event.addHeader("to", "1000(a)192.168.1.6") event.addHeader("from", "5000(a)192.168.1.6") event.addHeader("dest_proto", "sip") print(event.serialize("plain")) event.addBody("message contents") con.sendEvent(event) as result of print command I get : Event-Name: CUSTOM Event-Subclass: SMS%3A%3ASEND_MESSAGE to: 1000%40192.168.1.6 from: 5000%40192.168.1.6 dest_proto: sip but no message received in 1000 extension.

bridge two outbound calls but got different sdp
by Leo Wolf 25 Apr '20

25 Apr '20

Hi, I usr freeswitch to call out A & B, and want to bridge calls after A & B responded. After bridging the two call, I found out that the sdp codec negotiated from A and from B are different, e.g., 102 and 111. This will cause A & B codec not sync problem. Is there any way to force clients using specific codec in freeswitch? I have found out some code in switch_core_media.c: /* it could be 98 but chrome reserves 98 and 99 for some internal stuff even though they should not. Everyone expects dtmf to be at 101 and Its not worth the trouble so we'll start at 102 */ smh->payload_space = 102; Seems the codec send to clients always begin from 102? Many Thanks, Leo

ADD 2 ICE CANDIDATES mod_verto
by Jazmin Marina Florez Marino 24 Apr '20

24 Apr '20

Hello all, I am working with mod_verto in a scenario where I need to send public and private IP addresses as ICE candidates. When I modify the ext-rtp-ip parameter, it only sends one option as typ host ice candidate. However, for my implementation I need to send both. What I need is the combination of those ice candidates, something like this: a=candidate:8228103366 1 udp 659136 190.84.118.88 31028 typ host generation 0 a=candidate:3496438569 1 udp 659136 192.168.1.170 24210 typ host generation 0 Is it possible to add both ice candidates in the same SDP from configuration files?

Wrong number of tries with originate_retries?
by René Weiss 24 Apr '20

24 Apr '20

Hi, The documentation for originate_retries says "Number of retries before giving up on originating a call (default is 0)." Because of this I would expect that: - originate_retries=0 = 1 call - originate_retries=1 = 2 calls (1 try and 1 retry) - originate_retries=2 = 3 calls (1 try and 2 retries) -originate_retries=3 = 4 calls (1 try and 3 retries) But in my testing I get: - originate_retries=0 = 1 call - originate_retries=1 = 1 call - originate_retries=2 = 2 calls - originate_retries=3 = 3 calls My originate command is: originate{originate_timeout=5,originate_retries=<X>,originate_retry_sleep_ms=5000}user/662 &park() And my FreeSWITCH version is: FreeSWITCH Version 1.10.2-release-14-f7bdd3845a~64bit (-release-14-f7bdd3845a 64bit) Am I doing something wrong here, do I understand the documentation wrong, or is the problem in freeswitch / the freeswitch documentation? Thanks.

Auth rejected after upgrade to 1.10
by David P 23 Apr '20

23 Apr '20

A few questions I've asked before... 1) We're evaluating an upgrade to 1.10 from 1.8, and we found that verto can wss login but calls trigger "code": -32000 authentication required. What can we do to fix this? 2) We sometimes get MEDIA_TIMEOUT from our automated peer in a 1-on-1 conference. Can we use execute_on_media_timeout to attempt a new conference with the peer? 3) Can FS be made to provide TCP ice candidates in its answer sdp? (That is, does it support ICE TCP?) For users behind firewalls that block many UDP ports, this would allow avoiding added cost of TURN TCP. Cheers, David

Device / extension state (status) functionality at Freeswitch or get User (Peer) / Gateway (Trunk) state
by CpServiceSPb . 22 Apr '20

22 Apr '20

There is Freeswitch 1.8.5 built from sources worked on x64 Linux. I need to check / get internal users / trunck gateways state BEFORE using it to perform different actions in response of got conditions: 1. the called number is not exists in the directory at all; 2. the called number exist in the directory, but not registered at the time, for example don' t launch softphone; 3. the called number is inuse; 4. the called number is busy; 5. the called number is not answered due timeout 6. the called number is answered. Is there functionality looks like device and / or extension (user) state at Freeswitch as for example <dialstatus> or <channelstarus> ? How is the best way to get these different states for internal users, for each one and /or for trunk gateways, per each also ?

Join us for SIP Chronicles Live #1, featuring Giovanni Maruzzelli
by Maxim Sobolev 21 Apr '20

21 Apr '20

Dear Real-Time Friends and Colleagues! As many of you we have been totally devastated that we will have no chance to see you in the next few months to come. :-/ Some people in the community believe it might be years. I don’t necessarily agree with that opinion myself. Over the course of the last few years our team had a great time extending live coverage for some of those events that have been affected, got some experience and equipment. Instead of just waiting for the virus to clear, we decided to organize a series of bi-weekly live casts with some of the speakers that we have hoped to see at those events presenting their latest developments live and then answering questions from the audience. So without further ado, let me introduce our first guest Giovanni Maruzzelli, who is going to introduce his newest project SaraPhone ( https://github.com/gmaruzz/saraphone) Join us this Saturday, April 25th 4:30pm UTC and get a chance to ask Giovanni a question about his project live: https://youtu.be/mF9elIcVGE8 Or if you miss that opportunity, you can always watch the recording later on Sippy Labs channel on YouTube and email Giovanni your question at < gmaruzz(a)gmail.com>. SaraPhone is a bare bone SIP WebRTC phone, complete with most features real companies want to use in real world: HotDesking, Redial, BLFs, MWI, DND, PhoneBook, Hold, Transfer, Mute, Attended Transfer, Notifications, running on all Browsers both on Desktop and SmartPhone. SaraPhone is fully integrated with FusionPBX, the full-featured domain based multi-tenant PBX and voice switch for FreeSwitch. Based on SIP.js, SaraPhone works with all WebRTC compliant SIP proxies, gateways, and servers (Asterisk, OpenSIPS, Kamailio, Janus, etc). Initial author is Giovanni Maruzzelli, and SaraPhone gets its name from Giovanni's wife, Sara Hosseini. In addition to providing all of the usual DeskPhone functionality, SaraPhone got: - Desktop Notification for Incoming Calls - Live MWI update - Real Time BLFs status update - BLF click to call - Caller Name and Number Display - Call Error Cause Display - AutoAnswer - Network Disconnect Reload - Show and Set Caller-ID (incoming-outbound) Stay healthy, optimistic and productive! Also share, like and subscribe. See you soon!!! Regards, Max

Hello All Hope you are well and safe. I am being playing around mod_avmd. I am originating calls by originate command both are External calls on DID's through gateway. Is it possible to detect the avmd on both the legs A and B using that above module. Currently only one leg A is being detected. Thank You Vishal P.
