16.0.4.493 issues (voicemail, Firefox popup , Mac addresses)

[saint_]

Hi,
Since we upgraded to this version in our lab, 2 things are not working anymore:
If we go through the web interface, click the PLAY button on a voicemail, the phone rings, but:

1. No popup shows on Firefox (macOS 10.15.2) anymore to pickup the call
2. If I pickup the call manually, there is no voicemail audio at all

I also noticed that phones are showing twice (same extension, same model, sane name, same IP address, same MAC address) under "phones" in the web admin page.

Anyone else ?

perhaps give us some more lights on your install, starting from here

My apologies, you are right.

3CX 16.0.4.493 running on Debian, hosted in the cloud.
Phone is a Grandstream GXP2170 provisioned through STUN

This setup worked since release 16. We don't change anything in the lab usually to make sure the same conf is kept through upgrades. Firewall passed back in time, and again to today I just tried it. We did not made any mods on the internal (company) firewall where the phone is.

As you said you are using STUN, did you set phone SIP port, RTP range ports on 3cx side, have you done NAT rules on phone location , Have you set a static IP on your phone ?

Have you followed this 3CX Doc. , start step 5 for STUN:
https://www.3cx.com/sip-phones/grandstream-gxp21-series/
If you use 5060 on phone location, be sure no other device use 5060 on same site.

If you use more than one phone, each phone need is specific SIP port like 5062, 5064.... and specific RTP range following the first you used for the first phone.
Give static IP to each phones
Add nat rules according to SIP and RTP range for each phone

I removed this phone from the PBX.
I configured a SBC
Phone now connected through SBC
Same issue where if I hit PLAY on the web client page, I now see the popup window asking me if I want to pickup the phone, I hit pickup button, and nothing happens.
After that, the phone is just stuck. It won't ring if I call it, and it won't call if I try to dial something.

Again, this worked since release 16 came out. Did not change a thing, everything was fine until upgrade to 16.0.4.493..

when switch to SBC can you give some details on how to you did?
did you factory reset phone ?
did you change 3CX side to SBC mode for the phone.
Do you have unchecked pbx delivers audio while using SBC ?
How have you added phone to 3CX? phone seen alone in bold in cosole and then assign it to extension? other way?

 

[saint_]

• Deleted phone from 3CX Installation
• Factory reset the pho
• Installed fresh Raspberrian on RPI3+
• Installed / configured 3cxsbc from command line
• Phone showed up in PHONES , added it to its extension, without PBX Delivers audio

Typical install.

 

[AWS2P]

phone is up to date on firmware ?
Do you have other phone or other brand to test from SBC if same behavior?

Is your SBC same version ? connected green?

 

[saint_]

No other phone to test with, but for the third time, THIS USED TO WORK FINE and we did not change anything but upgrade to 3cx. It went through multiple minor software upgrade and worked fine. THIS one broke it. Yes, SBC is green with latest version running.

 

[saint_]

We removed all firewall rules internally between SBC and internet. The phone is not even ringing when it is called. Nothing to do with our network since this is within a SBC now and it handles everything. I'm bummed.

 

[AWS2P]

SBC is a windows or debian one?

 

[saint_]

Ha - Here is my fix. Delete the phones. Shutdown SBC. Reboot 3CX. Restart SBC. Activate the phones. Now it's working.. Jesus.
