Telegram VoIP phone calls
MadelineProto provides an easy wrapper to work with phone calls.
Full webradio example
Requesting a call
<?
php
if
(
!
file_exists
(
'madeline.php'
))
{
copy
(
'https://phar.madelineproto.xyz/madeline.php'
,
'madeline.php'
);
}
include
'madeline.php'
;
$MadelineProto
=
new
\danog\MadelineProto\API
(
'session.madeline'
);
$MadelineProto
->
start
();
$call
=
$MadelineProto
->
requestCall
(
'@danogentili'
);
The
requestCall
function accepts one parameter with the ID/username/Peer/User/InputPeer of the person to call, and returns a VoIP object that can be used to play audio files, set the hold files, change the configuration and set the output file (see the
VoIP API documentation
for more info).
You can play audio files of any format as follows:
Playing audio files
You can play audio files of any format:
<?
php
if
(
!
file_exists
(
'madeline.php'
))
{
copy
(
'https://phar.madelineproto.xyz/madeline.php'
,
'madeline.php'
);
}
include
'madeline.php'
;
use
danog\MadelineProto\LocalFile
;
$MadelineProto
=
new
\danog\MadelineProto\API
(
'session.madeline'
);
$MadelineProto
->
start
();
$call
=
$MadelineProto
->
requestCall
(
'@danogentili'
);
$call
->
play
(
new
LocalFile
(
"audio.mp3"
))
->
then
(
new
LocalFile
(
"audio.flac"
))
->
then
(
new
LocalFile
(
"audio.wav"
))
->
then
(
new
LocalFile
(
"audio_with_video.mp4"
));
You can also play remote streams (or simple remote files) by URL:
<?
php
if
(
!
file_exists
(
'madeline.php'
))
{
copy
(
'https://phar.madelineproto.xyz/madeline.php'
,
'madeline.php'
);
}
include
'madeline.php'
;
use
danog\MadelineProto\RemoteUrl
;
$MadelineProto
=
new
\danog\MadelineProto\API
(
'session.madeline'
);
$MadelineProto
->
start
();
$call
=
$MadelineProto
->
requestCall
(
'@danogentili'
);
$call
->
play
(
new
RemoteUrl
(
"http://icestreaming.rai.it/1.mp3"
));
You can also play Telegram files, using AMP streams!
Webhost support
Starting from MadelineProto 8, VoIP now works on webhosts, too, thanks to a pure PHP implementation of libtgvoip and a pure PHP OGG demuxer!
The only limitation when running on webhosts is that audio files must be preconverted using by sending them to
@libtgvoip_bot
(
source code
), or by using the following script on your PC:
<?
php
if
(
!
file_exists
(
'madeline.php'
))
{
copy
(
'https://phar.madelineproto.xyz/madeline.php'
,
'madeline.php'
);
}
include
'madeline.php'
;
use
danog\MadelineProto\LocalFile
;
\danog\MadelineProto\Ogg
::
convert
(
new
LocalFile
(
"in.mp3"
),
new
LocalFile
(
"out.ogg"
));
Copy out.ogg to your webhost, and then run this script on your webhost:
<?
php
if
(
!
file_exists
(
'madeline.php'
))
{
copy
(
'https://phar.madelineproto.xyz/madeline.php'
,
'madeline.php'
);
}
include
'madeline.php'
;
use
danog\MadelineProto\LocalFile
;
$MadelineProto
=
new
\danog\MadelineProto\API
(
'session.madeline'
);
$MadelineProto
->
start
();
$call
=
$MadelineProto
->
requestCall
(
'@danogentili'
);
$call
->
play
(
new
LocalFile
(
"out.ogg"
));
Accepting calls
Accepting calls is just as easy:
<?
php
declare
(
strict_types
=
1
);
if
(
!
file_exists
(
'madeline.php'
))
{
copy
(
'https://phar.madelineproto.xyz/madeline.php'
,
'madeline.php'
);
}
include
'madeline.php'
;
use
danog\MadelineProto\EventHandler\SimpleFilter\Incoming
;
use
danog\MadelineProto\VoIP
;
use
danog\MadelineProto\RemoteUrl
;
use
danog\MadelineProto\EventHandler\Attributes\Handler
;
class
PonyHandler
extends
\danog\MadelineProto\SimpleEventHandler
{
#[Handler]
public
function
handleIncomingCall
(
VoIP
&
Incoming
$call
)
:
void
{
$call
->
accept
()
->
play
(
new
RemoteUrl
(
'http://icestreaming.rai.it/1.mp3'
));
}
}
PonyHandler
::
startAndLoop
(
'session.madeline'
);
Recording calls
To record the incoming audio stream in a call, simply use
setOutput
:
<?
php
declare
(
strict_types
=
1
);
if
(
!
file_exists
(
'madeline.php'
))
{
copy
(
'https://phar.madelineproto.xyz/madeline.php'
,
'madeline.php'
);
}
include
'madeline.php'
;
use
danog\MadelineProto\EventHandler\SimpleFilter\Incoming
;
use
danog\MadelineProto\VoIP
;
use
danog\MadelineProto\RemoteUrl
;
use
danog\MadelineProto\LocalFile
;
use
danog\MadelineProto\EventHandler\Attributes\Handler
;
use
Amp\ByteStream\WritableStream
;
class
PonyHandler
extends
\danog\MadelineProto\SimpleEventHandler
{
#[Handler]
public
function
handleIncomingCall
(
VoIP
&
Incoming
$call
)
:
void
{
$call
->
accept
();
$call
->
play
(
new
RemoteUrl
(
'http://icestreaming.rai.it/1.mp3'
));
$call
->
setOutput
(
new
LocalFile
(
'output.ogg'
));
// $stream can also be a WritableStream.
// Can be used to pipe OGG OPUS audio data to ffmpeg, asterisk via amphp/process, amphp/socket, etc...
//
//$call->setOutput($stream);
}
}

startAndLoop
(
'session.madeline'
);
