dtls-srtp problem with firefox 84.0.2
by Stefan 22 Jan '21

22 Jan '21

Hi, I have a problem getting verto-communicator and/or mod_verto running with firefox. It works with chromium-based browsers without problems, but it looks to me (that means: I don't know exactly, but I suspect) as if the ciphersute to get the key for srtp is not perfect-forward-secure. Maybe that's the reason for firefox to fail, but I couldn't find any documented way to change the ciphersuite, neither in mod_verto, nor in mod_rtc (perhaps I oversee something). What I attach here are two logs. The first is the successful call to a conference witch edge (chromium based), the second is the try to do the same with firefox. Both logs begin at the same point, where verto does the state change CS_ROUTING -> CS_EXECUTE, the whole logs only differ after this point. Can anyone help me? In case it matters: the certs are from letsencrypt. __ s.

Limiting Calls Per Second
by Alexander Perkins 21 Jan '21

21 Jan '21

Hi All. I have a client that needs a second Freeswitch server and I need to figure out how to handle her 'calls per second' limit. Currently, although not perfect, it is not a big deal - I simply decrement or increment a column in a database. However, I am concerned that with a second server, I may run into collisions, etc. What is the best practice to have two servers accurately measure calls per second? Is there a module I can use or something without re-inventing the wheel? Thanks! Alex

Hi, Does Freeswitch still have verto javascript libraries? I looked in github for /js/verto/jquery.FSRTC.js and did not find it.

[FreeSWITCH sched_hangup does not execute 'execute_extension']
by Bilal Abbasi 20 Jan '21

20 Jan '21

Hi Users, I want to build a scenario in which if the B-Party hangup the call, A-Party can still be able to process through the dialplan. This works fine if B-Party hangup the call, but if the B-Party is hanup forcefully via sched_hangup (timeout), call gets terminated i-e A-Party is not able to reach 'execute_extension' application. Here is my dialplan snippet https://justpaste.it/2ppra I have attached as an image as well. Regards Bilal Abbasi

register with FQDN or IP
by Joli Martinez 19 Jan '21

19 Jan '21

Hello, I am running a small freeswitch system with several phones, users register with the IP of the freeswitch box. Since they are now working from home more, they need to be able to connect remotely. I have built a kamailio proxy and exposed it. I created an FQDN sip.mydomain.com and pointed it to the kamailio box. The registration comes in and kamailio sends it to freeswitch. On the freeswitch box my internal sip profile looks like this. I have also reloaded it. <domain name="all" alias="false" parse="false"/> <domain name="sip.mydomain.com" alias="true" parse="true"/> Registrations from the public internet still fail, but users registering with the IP work. What am I missing? 2021-01-19 12:19:37.480591 [WARNING] sofia_reg.c:1794 SIP auth challenge (REGISTER) on sofia profile 'internal' for [222(a)Sip.mydomain.com] from ip 1.1.1.1 2021-01-19 12:19:37.540512 [WARNING] sofia_reg.c:2930 Can't find user [ 222(a)Sip.mydomain.com] from 1.1.1.1 You must define a domain called 'Sip.mydomain.com' in your directory and add a user with the id="222" attribute and you must configure your device to use the proper domain in its authentication credentials. 2021-01-19 12:19:37.540512 [WARNING] sofia_reg.c:1739 SIP auth failure (REGISTER) on sofia profile 'internal' for [222(a)Sip.mydomain.com] from ip 1.1.1.1 Thanks

AWS - Audio Delay - rtp timer
by Jacob Greene 19 Jan '21

19 Jan '21

Hello everyone, Recently, I am running into an issue with some severe audio delay with some freeswitch boxes running on AWS. It gets to the point where audio is delayed up to 10 seconds in both directions. The calls start off fine and slowly get worse. The only way I've been able to fix this is by disabling the rtp timer on the sofia profile(rtp-timer-name=none). Making this change immediately fixes the issue. No obvious system bottlenecks, 1/5/15 min load averages all less 1 on dual core CPUs, tons of free memory, no I/O issues on the nic, etc. I suspect this might have something to do with some weird CPU sharing AWS is doing on their hypervisor, but I'm not sure. I can't find a ton of info on exactly what the rtp timer does, other than disabling it "disables asynchronous rtp" and "makes freeswitch handle media the same way as asterisks". I'm not really sure what this means. I've read it's less effecient and come across a couple very old post on the mailing list of Anthony steering people away from disabling the rtp-timer. Has anyone had a similar problem? Or does anyone have some more information/resources regarding exactly what the function of the rtp timer is? I'm trying to get in front of this. What are the drawbacks of not using an rtp timer? Thanks for reading!

Using last_bridge_hangup_cause
by olle＠zaark.com 18 Jan '21

18 Jan '21

Hi, I have a need of using last_bridge_hangup cause in a condition statement to activate a second call leg but I can't get it to work. The log line prints the correct values of last_bridge_hangup_cause, "NO_ANSWER" , but when I use it in the condition it's not working and the same if I try to assign it to another variable. Here is a code snippet I use in the dialplan: <action application="set" data="hangup_after_bridge=false"/> <action application="bridge" data="sofia/gateway/mygateway_1/1234567"/> <action application="log" data="INFO Last bridge hangup ${last_bridge_hangup_cause}"/> .. Do some stuff ... <condition field="${last_bridge_hangup_cause}" expression="NO_ANSWER"> <action application="bridge" data="sofia/gateway/ mygateway_2/1234567"/> </condition> I would prefer using the dialplan without implementing this in lua if possible. Any help appreciated /Olle

external ip and Nat
by Kakiman Expert 15 Jan '21

15 Jan '21

Hello I am working on freeSWITCH 1.10.2 with webRTC. I have a private address on my server, that is translated on a static public IP in order to reach webRTC/FS through Internet. In the vars.xml, i have then indicated this public IP as *external_sip_ip* and *external_rtp_ip *and everything is working. Now, I also want to be able to reach webRTC with its private IP, so what is the value to configure in vars.xml external_sip and external_rtp ? I can not put both public and private IP. thanks for your helpful answers Joe
