[Vtigercrm-developers] Asterisk Good News

[vtiger at camden.net]

self hosted opensips would be our preference and here is why
  
 currently we have 2 internet connections to deal with, our connection to 
the ILECS that we pay top dollar for the QoS and SLA on SIP/PSTN traffic, 
then the internet connection to our EU, that EU connection is 99% of our 
support issues, though we have ways of dealing with that to some extent in 
EU;s QoS with use of ingress and egress QoS capable routers
  
 a cloud based sip proxy would add a 3rd connection that we have no SLA and 
no real way of controlling QoS, no matter what it would add latency and 
jitter 
  
 so for us its pretty important to keep our switches, PBXs and any proxy's 
all in the same network we control, this is a quality issue more than a 
privacy issue, though privacy is a legitimate concern

  very interesting using a SIP proxy ;-), would love to check it out when 
you get it finished
  
 how will it handle inbound notification? a in browser pop like vtiger does 
now? 
 yeah, but probably based on web sockets rather than polling, if I can do 
that cleanly in a module without ridiculous dependencies.    
 when you say marketplace I assume extension store? 
 yup, it would be an open source solution, but packed up in the extension 
store for easy installation, possibly with a price tag on it a bit like the 
geotools module.   will this support complete 3rd party apps like the sip 
proxy server your building, from everything I read it seemed more geared to 
modules that install directly into vtiger
 well, yeah, that is an interesting question, and one reason why I parked 
the project for a bit. It might be that I run an opensips server as a 
service in the cloud for users of the module, and give instructions on how 
to run your own opensips proxy for people who don't want to have their 
telephone metadata going outside the organisation (other than to the NSA of 
course). One of the things I would have to figure out for a cloud based sip 
proxy is getting it to work and be maintainable, but store no logs, I don't 
want that data!
    
 if its going to support 3rd party applications we are working on a windows 
system trey call pop for vtiger so your browser can be minimized and you 
are still altered to the call with links to relevant records,  in alpha 
testing now but we would be interested in this extension store

   I did write most of a SIP module, I am planning to finish it off and 
perhaps put it in the marketplace once that is all up and running, it 
certainly doesn't require multiple extensions to do click to call and 
inbound, it uses a SIP proxy, basically a benevolent man in the middle 
attack on the sip signalling :) this proxy can see the calls in both 
directions being set up, the handsets think that the proxy is the PBX, the 
PBX thinks the proxy is the handsets. The proxy could be running on the 
same machine as the PBX, or the same machine as vtiger, or somewhere else 
altogether.

    SIP would not be the best idea, yes its even easier to deal with than 
AMI but asterisk can only handle 1 sip registration per extension so this 
will lead to the need to have 2 extensions, one for your phone and one for 
vtiger you would then need to daisy chain them in follow me
  
 same reason SIPTapi from IPcom never took off, yes you can get the free 
version and click to call outbound works with only one extension but if you 
want inbound you have to pay and will find out after you need 2 extensions
