Opus changes?
by Peter Villeneuve 24 Jun '14

24 Jun '14

I just realised that after updating to latest master, I can no longer negotiate Opus with CSipSimple. Before this latest update, it worked fine. I believe this maybe related to adding stereo but not sure. [DEBUG] switch_core_media.c:3469 Audio Codec Compare [opus:111:48000:20:0:2]/[opus:116:48000:20:0:1] [DEBUG] switch_core_media.c:3504 Audio Codec Compare [opus:116:48000:20:0:1] is saved as a near-match I have set "global_codec_prefs=OPUS,G722,iLBC,SILK,PCMU,PCMA,GSM" What do I have to change to have Opus available again? Thanks

ZRTP negotiation taking almost 10 seconds every time
by Peter Villeneuve 24 Jun '14

24 Jun '14

Hi, I've been trying to debug why ZRTP negotiation with FS as endpoint takes almost 10 seconds every single time. I remember in the past ZRTP negotiation used to take 2 to 3 seconds at most. I'm calling MoH extension from CSipSimple with ZRTP enabled to test it out and indeed it always takes 9 seconds to negotiate the ZRTP exchange. And even after it does it successfully and enteres secured state, I still see a lot of errors related to failed decryption. I have posted the FS and CSipSimple logs on pastebin. FS log here http://pastebin.com/WNGcpTqB and CSipSimple log here http://pastebin.com/DfW5gqSW These are the relevant excerpts from FS which may help to shed light as to what's going on. You can see that the zrtp hellos from FS apparently never reach the CSipSimple client: *2014-06-10 16:17:55.949864 [DEBUG] switch_rtp.c:1352 [ zrtp engine]: WARNING! HELLO Max retransmissions count reached (20 retries). ID=9* But then you see a five second interval of nothing until CSipSimple's ZRTP hello reaches FS and the negotiation starts: *2014-06-10 16:17:55.949864 [DEBUG] switch_rtp.c:1352 [ zrtp]: Stream ID=9 CLEAR switching <START> ---> <NOZRTP>.* *2014-06-10 16:18:00.789889 [DEBUG] switch_rtp.c:1352 [ zrtp utils]: Received <Hello > packet with ssrc=0 seq=1/1 size=168. Stream9:CLEAR:NOZRTP.* Once that's successfull indeed ZRTP appears to work properly, although I still see a lot of errors like this: 2*014-06-10 16:18:01.509898 [DEBUG] switch_rtp.c:1352 [zrtp protoco]: ERROR! Decrypt failed. ID=9:DH s=SRTP authentication failure (RTP size=51 ssrc=690666908 seq=20192/20192 pt=111)* *2014-06-10 16:18:01.509898 [DEBUG] switch_rtp.c:1352 [ zrtp engine]: Add 140 bytes of entropy to the RNG pool.* Now I guess this could be due to dropped packets, but I'm curious if others have seen the same thing in their setups. Also, I see this message in the FS logs. On the CS logs everything seems to be fine. Why does FS think that CS needs new un-enrolment? I presume that nedpint is actually a typo for endpoint, but this just made me more confused. *2014-06-10 16:18:01.769867 [DEBUG] switch_rtp.c:1352 [zrtp protoco]: INFO! The user requires new un-enrolment - the nedpint may clear the cache or perform other action. ID=9* *c60c4480-f0ba-11e3-aa6e-ddba267b1226 2014-06-10 16:18:01.769867 [DEBUG] switch_rtp.c:1323 User unenrolled!* *2014-06-10 16:18:01.769867 [DEBUG] switch_rtp.c:1352 [ zrtp cache]: cache_put() zid1=346638366666393864366363, zis2=3888449c219de624b44b3ece MiTM=NO* *2014-06-10 16:18:01.769867 [DEBUG] switch_rtp.c:1352 [ zrtp cache]: cache_put() Just update existing value.* Any ideas as to what's happening? Thanks

mod_verto INCOMPATIBLE_DESTINATION
by Ciprian Dosoftei 24 Jun '14

24 Jun '14

Hello, I am trialling the new mod_verto endpoint and so far it's been fantastic, definitely a great addition! I am trying to figure out what I am doing wrong in terms of codec settingss as I can only get it working with opus, PCMU will simply throw INCOMPATIBLE_DESTINATION if the channel is answered. On the very same system I don't have any issues getting PCMU over webRTC by using sofia's own WSS binding. Below are my codec string settings for verto (dropping opus will result in failure): <param name="outbound-codec-string" value="opus,PCMU,PCMA"/> <param name="inbound-codec-string" value="opus,PCMU,PCMA"/> Thank you! -- Best Regards, Ciprian Dosoftei The information transmitted is intended only for the addressee and may contain privileged and/or confidential material.

I'm trying to get the latest master version of Freeswitch running on Centos 6.5 (FS 1.4 works fine).

Hi, Is there is a way to call an external API (HTTPS/GET), to validate a phone number from the dialplan? <extension> <condition https://domain/api?par1=value, $ret-val> ?? <action application="bridge" .....> </condition> </<extension> I'm looking at mod_curl but not sure if I can use it in dialplan and/or how to retrieve the response. Any idea?

Different behavior of FS under gdb
by mayamatakeshi 24 Jun '14

24 Jun '14

I am testing latest commit b21f34bffc with CentOS 6.5. FS gets stuck at this point during startup: # ./freeswitch -nonat 2014-06-23 17:16:34.231865 [INFO] switch_event.c:670 Activate Eventing Engine. 2014-06-23 17:16:34.232154 [WARNING] switch_event.c:652 Create additional event dispatch thread 0 So I tried to run it under gdb, but when i do 'r -nonat' in the gdb cli, FS doesn't get stuck and starts properly (i get the FS CLI and I am able to execute commands in it). Any idea why would this be?

Can't output SUBSCRIBE/NOTIFY events
by Nandy Dagondon 23 Jun '14

23 Jun '14

Hello, I can't output the ff events from fs_cli: SUBSCRIBE, NOTIFY with these example commands: /event plain all /filter event-name notify Even without the /filter command, there's no output even though the messages were captured in pcap file. Where have I gone wrong? They're included in the Event List wiki. /Nandy
