installation
npm install sip-mrcp
Usage
const sip_mrcp = require('sip-mrcp')
const mrcp = require('mrcp')
const server = new sip_mrcp.SipMrcpStack({
sip_options: { // see available options at https://github.com/kirm/sip.js/blob/master/doc/api.markdown
address: '127.0.0.1',
port: 8092,
publicAddress: '127.0.0.1',
},
rtp_options: {
local_ip: '127.0.0.1',
local_ports: [10002],
},
mrcp_options: {
local_port: '9002',
},
new_session_callback: new_session => {
// accept or refuse the session
const answer_payload = {
id: 0,
codec_name: 'PCMU',
clock_rate: 8000,
}
new_session.accept(answer_payload)
// or
// new_session.refuse(404, 'Not Found')
// on a session you can wait for mrcp_msg and rtp_data:
new_session.on('mrcp_msg', msg => { // do something }
new_session.on('rtp_data', msg => { // do something }
},
})
const client = new sip_mrcp.SipMrcpStack({
sip_options: { // see available options at https://github.com/kirm/sip.js/blob/master/doc/api.markdown
address: '127.0.0.1',
port: 8091,
publicAddress: '127.0.0.1',
},
rtp_options: {
local_ip: '127.0.0.1',
local_ports: [10000], // list of RTP ports to be used by the stack
},
mrcp_options:{
local_port: '9001',
}
})
const sip_uri = "sip:[email protected]:8092"
const resource_type = "speechsynth"
const pcmu = 0
const offer_payloads = [
{
id: 0,
codec_name: 'PCMU',
clock_rate: 8000,
},
{
id: 8,
codec_name: 'PCMA',
clock_rate: 8000,
}
]
client.create_session(sip_uri, resource_type, offer_payloads, (error, new_session) => {
if(error) {
console.error(error)
process.exit(1)
}
console.info("new_session created")
// once you have a session, you can send MRCP requests
new_session.send_mrcp_msg(SOME_MRCP_MESSAGE)
// and handle MRCP msgs and RTP data
new_session.on('mrcp_msg', msg => { // do something }
new_session.on('rtp_data', msg => { // do something }
})
See samples/server.js and samples/client.js.
They were written to interact with each other.
You can test by cloning the repo and doing:
npm install
Then start them on separate shells:
node samples/server.js
node samples/client.js
