How to achieve MRCP server load balancing from FreeSwitch??
by Jignesh Vasoya 18 May '18

18 May '18

Hi, I was exploring an option to use mod-distributor for using a simple round robin load balancing between different MRCP speech servers. I have tried to fill in "default asr profile" using mod-distributor placeholders(variables). But it is not working?? Is there any way to achieve simple load balancing between different Speech Servers in FreeSwitch? -- *Thanks,* *Jignesh*

[VAD events][conference call]
by Bilal Abbasi 18 May '18

18 May '18

Hi Users, I want to get the VAD events on a conference call, i want to join a conference call silently and just wanted to get vad events. What i did is to land the conference call in a context and run echo application.(as vad events appears on b leg) But that caused noise in conference, so i droped the rtp packets using iptables rules. Problem: Everything works great, but now i want to traverse in conference(like pin etc) and i send dtmf 2833 which also get droped by iptables. Question: is there a way i can get vad events and be as a silent listener of conference as well. P.S: previously i used originate conference and landed on park(), but that do not generate vad events. So i switched to echo() Regards Abbasi

xml_curl for directory with verto

Ok I am now seeing post requests (small steps!), but cannot get an authentication success. Maybe something I’m misunderstanding (most likely!).

External authentication
by Rick Jarvis 16 May '18

16 May '18

Now, I’m sure I’ve read about this somewhere, and now I need to do it, I can’t find it of course! Basically need to hand the user authentication off to another server, via https. Got this kind of thing working nicely in the dialplan using httapi, but can’t figure out how to do it for user registration? Needs to be real time, so exporting directory XML *to* FS isn’t going to do it. Any ideas?

caching dialplan in xml_curl
by Akshaya j 16 May '18

16 May '18

Hi All, I just need to cache the dialplan response in xml_curl module. The wiki has an example of caching the directory response setting "cacheable=true" in user-id tag which perfectly works. I'm just curious to know is there a similar way to cache the dialplan as in setting same tag in <condition> tag? I worked around placing cacheable in <section>,<context>,<extension> <condition> nothing seems recognising it. I feel having the cacheable in <condition> tag is meaningful but even tat doesn't work. How do u people make this caching work in dialplans? Any thoughts on this would be helpful.! Regards, Akshaya J
