Can I get the headers of received CANCEL? about drachtio-srf HOT 17 CLOSED

It looks like this is where the CANCEL event is emitted:

from drachtio-srf.

@JSimoni42 ,

Thank you for your answer.
But I already tried to do that,

req.on('cancel', async (cancelReq) => {
...
});

But I think cancelReq.headers is not define.
Actually, I double checked that cancelReq is undefined in that case.
Is it a req object from CANCEL?

from drachtio-srf.

@xquanluu can you comment? I think we just dealt with this requirement recently

from drachtio-srf.

Take a look at this example:

expectCancel(uri) {
    this.srf.invite((req, res) => {
      req.on('cancel', (cancelReq) => {
        const headers = cancelReq.headers;
        console.log(headers);
      })
      this.srf.createB2BUA(req, res, uri)
        .then(({uas, uac}) => {
          throw new Error('unexpected dialog success - expected CANCEL from uac');
        })
        .catch((err) => {
          debug(`expectCancel: expected a final 487, got ${err}`);
          if (err.status === 487) return;
          throw err;
        });
    });
  }

Output:

{
via: 'SIP/2.0/UDP 172.29.0.2:5060;branch=z9hG4bK-1-1-0;rport=5060',
from: 'sipp sip:[email protected]:5060;tag=1SIPpTag001',

'call-id': '[email protected]',
cseq: '1 CANCEL',
reason: 'SIP;cause=200;text="Call completed elsewhere"',

@xquanluu

Can you give me version information about supporting cancelReq?

from drachtio-srf.

Can you use drachtio-srf: 4.5.28
drachtio-server: latest

from drachtio-srf.

@xquanluu

I use 4.4.18. After updating to 4.5.28, I will let you know the results.

from drachtio-srf.

@xquanluu

Can I get you tag information of the latest drachtio?
Is it same with 0.8.22?

from drachtio-srf.

Yes it's correct.

from drachtio-srf.

@xquanluu
But it looks different.
0.8.22 does not give me cancel object but latest give me.
I updated drachtio-srf to 4.5.26.
Any advice?

from drachtio-srf.

Can you tell me how you build and deployed drachtio? via docker?

from drachtio-srf.

@xquanluu
Yes. I installed Drachtio SIP Server via Docker. The image is from Docker hub.
Drachtio

I had some tests to compare 0.8.22 and latest and then I noticed that the only the latest one worked properly.
cancelReq is undefined with 0.8.22 and Drachtio SRF 4.5.26 was used for both cases.

from drachtio-srf.

hmm. Strange but yes please use latest tag.,

0.8.2 was released 2 months ago, from that time up to now there is no official release yet.

from drachtio-srf.

@xquanluu

I'm sorry to make you confused. Now 0.8.22 works properly.
Close this issue! Thank you for your support!
