Worthwhile VOiP providers

Following this thread keenly.

I would like to move away from a LTE PABX and move to a cellular solution only using existing mobile phones that works like a PABX (call routing, etc.). I saw one solution mentioned that runs on MTN, but I would like to hear feedback from anyone that has tried this or heard about it please.

We're using a hosted 3CX solution with apps on our smartphones. There are a couple of desktop phones at the office (reception etc), but for the most part we use our smartphones. We're able to transfer calls between users just like an old school pabx.

Hi Speedster.

Can you let me know who this is through please?
 
Check out mezobyte too for 3cx .they hosting ours with switch telecom VoIP trunk (for 50 users ) and it's been working a treat.

No issues except for Huawei phones with harmony OS. While those users install and register extension , it shows as unregistered so we can't call them directly. I guess 3cx just needs to come to party to fully support that OS.

3cx is amazing. Users don't need degrees in VOIP settings to use it. Install app, scan QR code and extension set up in 3 seconds

Hi

We implemented this solution (MTN carried PBX)

So basically it is a hosted PBX that runs on the MTN network. It uses 2G backbone and works as a normal cellphone. You are able to receive calls via your 08X number and via your ported landline number. You are able to dail ext 4XXX internally with minimal costs (0.1c p/min)

Let me know if you require more info

Nice. I have dropped you a note.
Do any other mobile providers do this, as I am not sure about MTN reception in my area?

I'm running 3CX on my local network on a Raspberry Pi and it works flawlessly. Tried hosted PBX's but they're rubbish for the most part. If you want something done properly do it yourself.

Using 3cx also. Been testing for a month. Hosting it on AWS Cape Town. Very good results so far.
Who are you using for your VOIP trunk?

I considered self hosting but decided to go with a hosting provider - need to focus on our core service and, for now, this would've been another time eating distraction

The biggest issue with hosting PBX's in the cloud is that all your internal calls (i.e. from one extension to the another on your local network) are go out across the internet to your cloud server and then come back, making internal calls very inefficient, network-wise. It also means if your internet connection goes down, your internal phone system goes down too. With a locally hosted PBX at least if your internet connection goes down you can still make internal calls from one extension to another. Auto-provisioning phones through a hosted PBX is also much trickier if the PBX and the SIP phones are not on the same local network segment.

We make hardly any internal calls when we're on the same premises

I have a Pi sitting at home going to waste, so please fill me in one how you did this as I might try it if it is not too complicated.

Anyone having issues on passing the 3CX firewall test for a self hosted install? Seems port 5060 is unreachable from international on ntt/DD/IS.

Is there any reason you need to have port 5060 open? If you're using a SIP trunk then there's absolutely no reason you should have any incoming ports open on your self-install instance.
