Re: [Server-devel] [XSCE] Proposal | SIP VoIP server on XSCE

For what it's worth, I also got asterisk and freepbx to work (atleast on
centos). It is definitely has more features than kamailio.. and allows for
stuff like voicemail, which can be especially useful in environments with
flakey connectivity. :-)

It might take a bit of time to package as I will be travelling soon, but it
is promising that it is working. :)

If SIP is using a server signaling messages always pass through the 
server
but audio messages (RTP flow) can travel end to end without passing 
through
the server. In IAX, signaling and data must pass always through IAX 
server.
This increases the bandwidth need by the IAX servers when there are 
many

simultaneous calls.


This is a big drawback of IAX it seems, especially in a mesh setup, 
where in
many cases, the available bandwidth between clients may be higher via 
direct
node routes compared with the bandwidth via the server route. It seems 
SIP

will utilize the network more efficiently in a mesh topology.

Yesterday we were testing this on the server, and two nodes with three
client. The data was being sent directly client -- node -- node -- 
client,

and virtually no bandwidth was being used on the server. :)


Not always the case. One of my students worked on her thesis where she
set up a bunch of XO-1 laptops over a 802.11s (draft) mesh and tested
simultaneous calls to look for saturation, etc.

It might be worth talking to the Village Telco folks and see if you can
do something that'll work with their solution.  See:
https://villagetelco.org/mesh-potato/

They're using Asterisk on their devices.

Re: [Server-devel] [XSCE] Proposal | SIP VoIP server on XSCE

[Samuel Greenfeld]

The downside to SIP is that if you leave a SIP server open on the Internet
which allows calls without authenticated registration (even by accident)
you will find dozens of systems trying to proxy long-distance &
international telephone calls through it.  If they can get through,
thousands of dollars of those calls may be billed to you.

SIP also has some firewall issues, although those can be mitigated with
proxies, a STUN server, and the proper configuration.

IAX2 historically has been meant to be an "Inter-Asterisk" server trunking
protocol, not something for individual clients.

Re: [Server-devel] [XSCE] Proposal | SIP VoIP server on XSCE

[Anish Mangal]

This looks interesting, but I would prefer to stick with SIP

Reason:
1. It is extremely scalable from running on tiny openWRT routers to big
servers
2. It is supported by a large number of free/open clients on ALL platforms.
There is also a webRTC socket for it.

The only current drawback of Kamailio right now, is there dont seem to be
ootb rpms available for arm. If there is a SIP server out there with ARM
packages, would love to test it, or otherwise - compile kamailio for ARM

Will look into IAX2. Is it supported by apps on different clients? For SIP,
there are usually many client options available on various platforms.

What server/service are you using? Look at IAX2 as well. Usually IAX2 does
better on networks because unlike SIP, session initiation and voice call
happen on the same port.

I think it's a good idea. Are you thinking Asterix? Does it change networking 
or just sit on top?

Subject: [XSCE] Proposal | SIP VoIP server on XSCE

Hi,

A SIP server on the XSCE will allow for VOIP services (audio, video, text). 
There are numerous SIP clients on various platforms so it seems a good protocol 
and standard to build upon.

I have already included a SIP server in the upcoming deployment of XSCE and 
mesh in Spiti, north India.

Thoughts?

Best,
Anish
