SIP flow visualization is not working when changing web application port to some other port

[ishvaram]

I've encountered with strange issue when I changed with the new port for the web application its everything else is working. But not sip flow visualization when I click it. its keep on loading and visualization is not coming for selected Call-ID

I've checked this with both Chrome and Mozilla to double-check its not an browser issue

below is the error that I see in the console.

main.1adcddffcc54c3672a03.js:75516 ERROR TypeError: Cannot read property 'protocol_id' of null

Using Homer 7.7 golang app.

sorry, can you please be more concrete ? What did you change ? Where and why ?

[ishvaram]

@adubovikov I've changed the http_settings

  "http_settings": {
    "help": "Settings for the HOMER Webapp Server",
    "host": "0.0.0.0",
    "port" : 80,
    "root" : "/usr/local/homer/dist",
    "gzip" : true,
    "debug" : false
  },

the default port is 8080, I want to run the application on port 80. So changed it.

with the port being 8080 all the functionalities are working, but if I change the port to 80 or some other port then SIP flow visualization alone not working

[adubovikov]

please check if your API has been sent to the correct port. In the browser -> F12 -> network tab

[ishvaram]

@adubovikov Yes, it is going to the correct port. This is what I've verified at the first place

[ishvaram]

@adubovikov Also i wanted to know is there a way where i can show only one transaction for a given call-ID. currently we're showing all the INVITE,100, 180, 183, ACK , BYE events as rows in the widget for a given call-ID. Instead of that can we show only transaction one per call-ID

[lmangani]

Hi Kovalan,

Transaction tracking feature is currently only available in HEPIC (hepic.tel). Lets keep this issue relevant to the report to avoid confusion.

[ishvaram]

@lmangani Ok I understand and inline that we should keep this in separate. But I didn't get why this needs to be raised hepic. What exactly you mean by Transaction tracking feature? What i need is just one row per call ID instead of showing all events in Homer UI.

@adubovikov Do you have any suggestions?

[adubovikov]

if it goes to correct port, check if you have received any data in this API call. Some examples will be not bad. Also, please provide the topology, because we have tested homer-app on port 80 and we don't have any issues so far

[ishvaram]

@adubovikov I just re-build homer-app again and now its working fine.

One last question: is it possible to show one record per call instead of showing all the rows in homer-app?

[adubovikov]

@ishvaram as @lmangani wrote already, if you don't have own CDR and want to generate them base on your SIP messages, this feature is availble in HEPIC platform (hepic.tel)

and we glad that you solved your issue. Don't forget to star our project:

https://github.com/sipcapture/homer/stargazers

[ishvaram]

@adubovikov my question is slightly different, I don't want to generate a CDR from this sip trace. I just need a different visualization

Currently, for one call I've traces like below showing all the transactions in the UI for one call.

But instead, I need only one trace per call to be shown on the dashboard of homer. like below

[adubovikov]

@ishvaram this is CDR/TDR view - Call Detail Record ;-) you can isolate your trace filtering by method INVITE

[ishvaram]

@adubovikov is possible to apply the filter by default when i open the widget, instead we manually applying filter?

[adubovikov]

@ishvaram you can implement it using your local storage. The project is open for contribution :-)

[ishvaram]

@adubovikov Can you give some more insights. Ready to take this up and contribute :)

[adubovikov]

you have to read/write the settings from/to your local storage. You can check how it has been implemented in the proto search widget.
