1. IAX2 uses a single UDP port 4569, and thus works well in NAT environments. IAX2 uses ONLY one udp port for both control and data traffic. As outlined in point 4 of the IAX versus SIP topic with IAX you will always have audio if the control connection can be established.
2. IAX2 supports PKI-style authentication and trunking.
3. The Asterisk IAX2 driver has a jitter buffer. (The SIP driver doesn't in 1.2.x, but one has been added in 1.4.x. The IAX2 jitterbuffer is more mature however.)

Jitterbuffer
One of the major advantages of IAX2 over SIP is the IAX2 jitterbuffer (in Asterisk 1.2.x and higher). This tends to improve the audio quality noticeably over non-ideal links like ADSL. To enable it, add:

jitterbuffer=yes

što se tiče router-a to bi trebalo biti to, sada ide podešenje iax2 trunk-a, a to je već rađeno na #14346

podesio sam

• fbze iax.conf
• fbde iax.conf

prema uputama kako sam to testirao, međutim na obje strane dobijam:

kada faruk mene zove

a inače sam nešto skontao.. uopšte ne treba ona linija register => ....@asterisk..... itd... u iax.conf

što se tiče greške, ti pokušavaš da dial kontekst demo, a u fbze postoji kontekst fbze koliko znam - znači ne valja ti dial plan

by the way, u fbde bi trebao podesiti, analogno podešenjima u fbze kontekst fbde, tako da postavke budu transparentne

e nakon podešenja #15294 firewall-a sada je ok

izvršio sam izmjene u fbde da je glavni context fbde

ništa rekao sam im sutra između sebe da se prozivaju da vidimo ko će se čuti a ko neće i slično

nije mi jasno dokle si ovdje stigao.

da li si podesio zvanje fbde via fbze vanjskih linija i obrnuto

koliko mi je poznato register .. iax kanala je za to neophodan

ovo je stanje na fbde trenutno

http://www.voip-info.org/wiki/view/Asterisk+bandwidth+iax2

Past threads on the asterisk-dev and asterisk-users lists have indicated that the optimal way to save bandwidth on multiple calls to the same destination is to use IAX2 (Inter-Asterisk eXchange version 2) in "trunk" mode, which eliminates IP overhead to a large degree.

This trunking eliminates the IP overhead found in individual VoIP IP streams by pipelining RTP data from multiple calls into single (larger) packets, thus removing the redundancy of IP overhead for each RTP stream and more closely allowing bandwidth scaling as a function of codec usage instead of a function of (codec usage + IP overhead.)

Of course, this mode can only be used if all the calls are between two specific Asterisk servers, but this is frequently the case with toll-avoidance situations or between two branch offices where there is an Asterisk server at each location.

http://astrecipes.net/index.php?n=204

We imagine that we have two Asterisk boxen, called foo and bar. foo is at 192.168.1.2 while bar is at 192.168.2.3. Le's start with foo; here is its iax.conf file:

[general]
bindport = 4569           ; Port to bind to (IAX is 4569)
bindaddr = 0.0.0.0    ; Address to bind to (all addresses on machine)
disallow=all
allow=ulaw
allow=alaw
allow=gsm
mailboxdetail=yes

[bar]
type=friend
username=foo
secret=password123      <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
auth=plaintext
host=192.168.2.3
context=fromiax
peercontext=fromiax
qualify=yes
trunk=yes               <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

This configuration means that on foo we can do Dial(iax2/bar/23) and this will call extension 23 at context from iax on bar.

podesio na fbze password, i takođe da se fbde athentificira sa tim password-om

s tim što je ovaj gore log praktično neiskoristiv - osječen je veliki dio teksta

što se tiče "NO AUTHORITY FOUND" to je mislim najobičnija poruka kada jedan server ne može uspostaviti konekciju sa drugim: slično kao na "ping - no reply"

dobro i to je loghično .....

od osvježenja ništa izgleda

izgleda da u tu svrhu koristi opcija register => u iax.conf-u ona svakih nekoliko ponovo registruje server

jeste jer kada sam stavio na fbde strani ovo

adresa njemačke se saša nije promijenila

naime fbde ima fiksnu adresu i pozivi fbze -> fbde bi trebali uvijek bez problema raditi

čitam knjigu asterisk the future of telephony i tu imaju detalji i spajanju dva asteriska via iax-a

tu sam našao autokill=yes komandu koja bi trebala uraditi ovu refresh stvar

(10:49:45) hernad: pa je li sada radi ?
(10:49:48) vsasa: sad je nakon restarta routera zadnji put odmah proradilo
(10:49:49) vsasa: da 
(10:49:52) hernad: bez tvoje interencije
(10:49:56) vsasa: dada
(10:50:08) vsasa: samo što imam ove nebuloze oko ip adresa - kako ih on prikazuje
(10:50:21) vsasa: stavio sam to na ticket
(10:50:24) vsasa: ali fakat veza radi
(10:50:25) vsasa: odmah
(10:51:09) hernad: ne ne radi sa strane fbde
(10:51:16) hernad: pročitaj ticket
(10:51:29) hernad: fbde => fbze je sporna

sada ću ja uzeti da napravim podešenja po knjizi

da, ali upravo se desilo maloprije da nakon restarta ja njih nisam mogao dobiti fbze->fbde i gore već stoji šta je izbacio na komentaru 52 i 53

drugi put:

nakon register linije i restarta routera veza je odmah ok.

i usput, register sam dodao samo na stranu njemačke, jer njemačka nezna našu ip adresu, a mi njemačku znamo.

znam da je fbde statička a fbze dinamička adresa !!! toliko sam valjda upoznat za ovo vrijeme

ja ti saša objašnjavam zašto veza prema njemačkoj radi, zato naglašavam da je statička adresa

fbze mi ovo kaže

podesiću da je fbde dynamic

nakon toga na fbde dobijam registraciju:
m1*CLI> iax2 show registry

isto tako i na fbze dobijam registraciju

znači imamo u ovom trenutku sve peers kažu da je OK, svi registry - registrovani.

idemo restartovati router fbze

izvršio reboot router-a

još info-a oko register komande

The register command¶

When the ip of the peer is unknown, a user has no way to place a call (e.g. when an office/user calls a teleworker/peer at home, where the teleworker has only a dynamic ip or is behind NAT.) To compensate for this, the teleworker/peer actively registers with the office/user by providing its identity and ip location.

On the peer, in the [general] section of iax.conf, add a registration entry:

 register => user:password@hostname.domain.ext

The continually updates the user so it will always know how to reach the peer even if the peer's ip changes.

The "register" statement only works if you want to hook up a server with a dynamic IP to a server with a static (public) IP, i.e. on the user you must add "host=dynamic" in the iax.conf for that peer.

If both servers are at known, static IPs then there is no need for a register statement as you'd use host=hostname on both ends.

dakle, to je to što nam treba

moguća rješenja problema dinamičke adrese¶

1) openvpn konekciju uspostaviti fbze => fbde, pa će fbde uvijek vidjeti lokalnu adresu 192.168.66.1 bez obzira na refresh internet ip-a

2) vidjeti da se nađe parametar koji će ovaj reload uraditi bez ručne interfencije

3) napraviti rješenje koje bu pokrenulo iax2 reload kada fbde detektuje da je došlo do promjene fbze ip-a

(11:28:54) hernad: de ti sada provjeri rad
(11:30:05) hernad: je li sve bitne stvari funkcionišu a problem dinamičkih adresa ćemo kasnije rješavati

mislim da sam našao gdje se štima:

/etc/asterisk/dnsmgr.conf

in the dnsmgr.conf file you need this.

[general]
enable=yes
refreshinterval=300

[general]

enable=yes              ; enable creation of managed DNS lookups
                        ;   default is 'no'
refreshinterval=90      ; refresh managed DNS lookups every <n> seconds
                        ;   default is 300 (5 minutes)

uradio na cli "reload" - sada vidimo da je polje dnsmgr-a "Y" u registry-ju

m1*CLI> iax2 show registry
