I've Had similar issues. I've found on some Android smartphones turning off the "noise reduction" in the dailer app settings can help. Though it's going to make their calls noisy so I don't find it to be a great solution.

You always have the weirdest issues...

That's because he only reports the issues he can't resolve.

Asterisk GUI is not there yet in usability. It functions, but the usability is just lacking yet.

I am leery of FreePBX due to the Sangoma buy out.

Elastix is only stable on an old as dirt system.

Just damnit.

Just seen a nice post on the Elastix forums. Someone went through the trouble to manually compare a 2.4 install and list the updates needed.

I think I'll be testing this out.

I saw the talk of "filesystems" as "backup." Getting to CentOS 7 would be good, although CentOS 6 would be good enough. The talk of backups makes no sense.

Was it just the nic driver or single nic shared by many vms?

Having to put in IP's doesn't allow for roaming users.

It can be done by extension, so some extensions are locked and some can roam. You can lock to IP blocks as well, so roaming just within regions.

Are you less worried about this because of the IP Tables AJ mentioned you wrote?

You should see this thing. It's extensive.

Thanks @JaredBusch I will reach out to you on Monday to discuss the details!

I read that....but i want a client. we want more we want more.

I thought I read somewhere there was a client that worked with Hylafax, but I'd rather punch a wall and break my hand than try messing with it.

baha good luck with that! yes, i have tried a couple oft these clients to no avail.

What are the pros and cons of implementing an open-source PBX as opposed to a proprietary system?
I've worked in shops that ran Cisco Unity, and after that - Shoretel. I found Shoretel to be a great deal easier to learn over the Cisco system and had a fairly easy time administering it.
How do these compare to something like Elastix or Asterisk?
3CX is also a good solution, but it is not an open source one. I personally do not prefer it, but if you have a windows license to spare for a VM, it is quite easy to setup and not nearly as expensive as other options.
I use PBX in a Flash simply because I do not need the simplified Elastix interface and I want more up to date versions. If the Elastix team put more effort into staying updated I would use it everywhere.

You hit the nail on the head about the true cost of switching the phone system though. No matter what you go to, if it is not a true upgrade,you will have to redesign all of the call handling from scratch. The thing you need to validate with you upgrade is whether or not it is a 100% no reconfig needed upgrade. If there is time not accounted for to do something like that, then you just leveled the playing field again.

This was something @FiyaFly and I worked on together, and I believe he was the one who fully resolved it by changing the baud rate settings on the physical fax machine. But I can say for a fact that this setup worked and is still working today at the site in question.

good job 🙂
