Use Cases > API calls, GPIO and Audio

SIP

http://192.168.1.99:8586/api/call

Where IP - address of the RPI

POST or GET method

If POST then in format JSON, if GET then parameters separated by &

There are 4 type of actions: call, answer, hangup, media

call:

{'account':1,'action':'call','to':'123456','speaker':'on','mic':'off'}

?account=1&action=call&to=123456&speaker=on&mic=off

account - id of the account from who to make a call

to - number where to call

speaker and mic - ON or OFF- to mute or un-mute during the call

answer:

{'account':1,'action':'answer'}

?account=1&action=answer

to answer the call on particular account

hangup:

{'account':1,'action':'hangup'

?account=1&action=hangup

to kill the call

media:

{'account':1,'action':'media','speaker':'on','mic':'off'}

?account=1&action=media&speaker=on&mic=off

way to control Microphone and speaker on specific account

during the active call

GPIO

http://192.168.1.99:8585/api/remote

Where IP - RPI address

POST or GET request

If POST then JSON format, if GET then parameters separated by &

Control Inputs / Outputs

{'auth':'12345abdcd','cmd':'onoff','gpio':'P1Pin7','duration':1000}

?auth=12345abcd&cmd=on&gpio=P1Pin7

where auth - authentification string under field 'EMS'

gpio - this is ID of the required GPIOor of the MCP

duration - in milliseconds

If gpio is set as an Output:

cmd=on -turn On output (LED On)

cmd=off - turn Off output (LED Off)

cmd=onoff - turn On, wait duration x milliseconds and turn Off

If gpio configured as an Input:

cmd=on -emulare a unui signal aplicat gpio (pressed and Hold)

cmd=off - emulare a disparitiei unui signal pe gpio (Released)

cmd=onoff - emulare unui impuls pe gpio (Pressed and Released)

cu impuls lung = duration in milliseconds

parametrul duration e necesar numai chind avem cmd=onoff

Exemplu:

http://172.16.16.205:8585/api/remote?auth=12345abdcd&cmd=onoff&gpio=P1Pin40&duration=5000

Audio will play on any trigger if seleced.
