I have a need to connect to an asterisk box running iax -- what happened
to mod_iax I can't find it anywhere?

Thanks.

A tear in time and space has caused the flux capacitor to not function properly so we had to retire the module since the lib didn't work right anymore.

If you do really want to use IAX, there is a solution: Use Asterisk as
an IAX protocol translator and have it to forward all the calls via
SIP to Freeswitch.

Hi,
There is another solution.

As discussed at Cluecon.
There is most of the iax code available in the opal/ptlib libraries.

Sure - opal&ptlib don't build in freeswitch - some issue about this was
mentioned at cluecon this year. However, the build script in freeswitch
(from when I last looked) uses a branch version of ptlib and trunk version
of opal.. Not a good mix. Better to use the trunk revision of ptlib&opal
-- where ptlib&opal come from the same SVN revision number.

Ok - there needs to be an iax registrar put into the opal code - bounties
anyone? and you never know - it would be quite doable..

The voip protocol side of iax is useful - and great for people to use when
connecting from an unknown position to some server on the public internet.
Sufficiently useful to make it worth using.

Who is game to work with me in getting the answer?

Derek.

While IAX is good for penetrating NAT issues. There is no good solution to
load balance IAX registration or calls. So if you want to build something
scalable, it is better to use SIP.

Hi,
Surely not.

While IAX is good for penetrating NAT issues. There is no good solution to load balance IAX registration or calls. So if you want to build something
scalable, it is better to use SIP.

The iax server issues a call transfer command, to transfer the incoming
call to a different server.

you do have to write the logic to decide when/where to transfer the calls.

IAX is also great for saving bandwidth by using the "trunk" mode.

Brian,
is that a protocol - or implementation issue?
My understanding is that the protocol is going to save you bytes on the
network...

However, sip&h323 also have trunking type systems, which will also save
you bytes on the network..

Derek.
Further - when the packet loss starts to happen, you have other issues..

Derek.

From an unknown position on the internet STUN usually works just fine.
The * people loving saying STUN is all very bad, but a recent exchange
on their mailing list seems to indicate none of them understand it. :-)

If you like this media through the signalling server scheme, I have a

forecourt of the dealer who supplied it. :-)

our current position on iax is as follows;

mod_iax is in the unsupported repo and already is probably not
compiling due to recent changes to the core.
The protocol exposed backwards incompatibilities that led to crashes
so we no longer trust it in our codebase.

We feel that in order to support IAX we either need to go with derek
and opal or build a completely standalone robust IAX stack which is a
much more complicated, expensive and almost academic of a solution at
this juncture.

yeah - we could invent snap - shit not another protocol
with a TCP port for signalling. Media is in rtp packets for ease of
interchange with h.323 and sip..
42424 would be the port I would use - for tcp and udp.

31415 would also do, I suppose..

But that is hard to get enough people to use it, to get the number of
users to make it worthwhile.

Another scenario is, in countries where regular SIP / H323 is blocked, IAX
is mostly not so, and therefore helps.

I personally prefer to work with H323 / SIP. But, ground realities are a
bit different at times.

We are using iax trunk feature to save bandwidth, it makes lot of sense when
your branches/offices are connected through a dedicated radio/fiber, we end
up saving millions per year using IAX,

@Brian, for me it always worked like a charm, never faced quality/packet
loss issues with ~20 concurrent calls over iax trunk in business hours.

I hope someone will take this challenge someday and rewrite more robust iax
stack for FreeSWITCH :)

Thanks and best regards,

Perhaps that would be something you could spend some of the millions
per year you are saving to finance.
It could benefit any project that wants to support IAX if it were
properly licensed to BSDish.

Hi,
Most of it is there in mod opal.

Just need someone to put up a bounty, and people like me can finish the
opal code.

The same idiot that put the IP in the UDP header?

But what idiot had the ip address in the data -- bad idea or so it seems
to me.

Why is everyone dead set on using IAX? you know SIP works fine and can traverse NAT if you know how to set it up properly.

Hi,
the voip protocols (sip & h323) had their genisys two decades ago - long
before there were agreed on "best practices".

putting the ip address in the packets made things like transfer easier to
do, or directing the media to a different box.

Derek.

If you do really want to use IAX, there is a solution: Use Asterisk as
an IAX protocol translator and have it to forward all the calls via
SIP to Freeswitch.

In reality, it is not easy! ICE, TURN, STUN, UPnP. wth so many RFCs.
that is why Skype is more popular even it is not open standard.

Hi,
cause most sip phones I have tried suck.

Typically, the UI is broken, and hard to follow.

When a user gets an iax phone, all they have to do is set the locn of the
remote server, and "it just works".

Remember, your average user does not know what a file is, or how to use
one.

"if you know how to set it up properly".
ok - this statement means that SIP is good for 0.1% of the population..

Derek.

This thread seems to go into a discussion on pro and cons of IAX in
particular cases...

As anything, IAX can have users that find it useful.

Problem is, the "open" (as in BSD compatible license) implementation
of the IAX stack is broken, and to write a new stack is a *really* big
work, that takes time from professional programmers and testers.

So, at end, problem is: the peoples/companies that would like to use
IAX with FreeSWITCH (or other software not GPLed) are willing/able to
raise enough money to fund the development of a working and reliable
IAX stack?

Maybe the people/companies interested can start a fund raising via
web, launching a sort of consortium for that...

Hi,
the opal library contains an IAX implementation that did voice calls
to digium.
At one stage, it did call transfer.

along came the iax management, who added this call token thing to the iax
protocol. The opal code contains call token handling.

Remaining?
to write an iax registrar, and find a way to ensure that all this can
talk with freeswitch.

license?
the opal implementation of iax and h323 and sip is all MPL.

connectivity with freeswitch?
There is code in freeswitch to talk to opal to do h323 calls.
Since opal uses a normalised approach to voip protocols and consequently
all protocols look the same to the management software, there is little to
do to get connectivity with freeswitch.

code quality?
the opal code for iax is heavily documented, is readable and nice.
it is heavily multi-threaded, so will cope with huge call volumes.

So what is remaining?

web, launching a sort of consortium for that...

Exactly - but there is only one way to go that has a chance of working,
which is to use the opal code.

Derek.

Has anyone figured out how much money we're talking about?

Hi,

SIP phones have been made easy for their target market to use, and end
users are not their target market. Service providers are the target
market, and SIP phones are mostly made easy for those people to
provision and control in volume. Unless a strong end user market for SIP
phones develops, this won't change.

Most IAX phones sit outside this, as they are mostly made by people who
simply can't get into the high volume service provider business, where
they want to be. Usually they are second division phones, as well as
second division suppliers. The good hardware runs SIP.
