Webphone

[KonradSC]

Hi All,

I wanted to share my webphone that I'm working on using a modified version of ctxSip. It includes an updated version (0.15.6) of Sipjs which required me to make some adjustments to webphone/phone/scripts/SIP.js/sip.js in order to get hold and mute working correctly. I had issues with one-way audio using the older sipjs version 0.7.8.

Before you attempt to install this make sure you have webrtc working on your system!!
Use this link to test it out: https://collecttix.github.io/ctxSip/

Brief instructions...
1. Make sure you have webrtc up and working. See above.

2. Is webrtc working? Read through this thread if you are stuck. https://www.pbxforums.com/threads/tls-and-webrtc-enablement.146/

3. Download the webphone files and stick them in your /var/www/fusionpbx/apps directory
https://github.com/konradSC/Fusionpbx-Public/tree/master/Apps/webphone

2. Change owner
chown -R www-data:www-data /var/www/fusionpbx/

3. Upgrade Permissions and Menu



A few things...
1. I'm not a JS programmer, so a lot of this was hacked together. I'm open to suggestions on code changes.
2. The wss port is hard coded to 7443. You can adjust that in webphone/phone/index.php. Update the hardcoded variable or use a session variable.
3. There seems to be a two or three second delay in call setup. It could be the ICE or STUN setup. I haven't spent too much time troubleshooting it yet. Let me know if you have a fix.
4. I'm releasing this so the community can test it out. If we get a solid version of this webphone then I'll submit it to the Fusion project.

Thanks,
Konrad

Hi there!

I am trying this and getting an 'Access Denied' error when trying to hit: https://mydomain.fusionpbx.com/app/webphone/webphone.php

I have changed ownership as suggested and have verified the permissions of this folder in /var/www/fusionpbx/app/webphone:
drwxr-xr-x 4 www-data www-data 4096 Apr 22 10:36 webphone

However I'm still not having any luck. I've updated permissions and menu, logged out and back in, etc. What am I missing?

 

[Kenny Riley]

Ahh ignore this, my superadmin permissions were protected and not updating. Thank you Konrad, I'm excited to play with this!

Looks good, does this work on 4.4 or only master branch?

 

[KonradSC]

I've only tested in Master, but perhaps it might work in 4.4.

I've only tested in Master, but perhaps it might work in 4.4.

I just tested it on 4.4 and was getting the following:

Fatal error: Uncaught Error: Class 'token' not found in /var/www/fusionpbx/app/webphone/webphone.php:44 Stack trace: #0 {main} thrown in /var/www/fusionpbx/app/webphone/webphone.php on line 44

Any idea's on how to resolve that?

 

[KonradSC]

4.4 has token security. Perhaps comment out the lines in https://github.com/konradSC/Fusionpbx-Public/blob/master/Apps/webphone/webphone.php with the word "token" to make it 4.4 compatible.

<Disclaimer>Master branch (4.5) has a lot of security improvements so from my understanding that is the recommended version for now. </Disclaimer>

 

[markjcrane]

FusionPBX 4.4 is a previous release that is now insecure and unstable compared to FusionPBX 4.5.

FusionPBX 4.4 is a previous release that is now insecure and unstable compared to FusionPBX 4.5.

Is 4.5 production ready or should is it best to wait for the 4.6 release which I'm guessing isn't too far away.

 

[markjcrane]

I would say 4.5. However it depends how much risk you want to tolerate by staying on 4.4.

I noticed that this client is using INFO for DTMF. You may want to add something like this to your dialplan in order for DTMF to be processed.

    <condition field="${sip_user_agent}" expression="SIP.js">
        <action application="set" data="dtmf_type=info"/>
    </condition>

have you able to fix the #3? i am also experiencing a call delay about 3 to 5 secs.

 

[wa4zlw]

we're seeing call delays as well

 

[killua77]

I found two bugs from console using the webphone
(1) #2
(2) #3

I will post the solution once I found a fix

I'm getting this same error. File and folder permissions ok.

Group Permissions: protected -> false

Can't see it in neither permissions nor menu manager.

Hi all. Just testing this now. The webphone loads but is not able to send/receive calls. Not seeing anything in the CLI.

I have an SSL cert and TLS is enabled/working. Under SIP status wss is showing as being on the private side IP not public.

Is there a variable to ad such as ext_sip_ip to bind this to the public IP?

 

[mydigitalself]

Got it working.

Delay when dialing, but aside from that it seems pretty good.

 

[mydigitalself]

Not sure if this useful, but the delay might be on the side of freeswitch with dtls negotiation. I'm on 1.10.3 and my logs/captures reflect what was reported last November.

Freeswitch-1.10.1 calls the webrtc client will have a dtls negotiation delay · Issue #109 · signalwire/freeswitch

When the freeswitch and the webrtc client negotiate the dtls, when the client sends the client Hello, the server does not immediately send the server hello to the public network address of the clie...

@mydigitalself, Good catch. I'll look at that on my end too.
