I have my IP PBX working, it works with remote extensions and everything works perfectly,

I have ports open on my router forwarding to the internal IP address of the PBX but when I check whether I can see if the ports are open from canyouseeme.org it tells me port 5060 isn't open, yet it is, is this weird or have I missed something really obvious?

It's not surprising, it depends entirely what it's doing to test for open ports.

You really need to understand the deeper aspects if TCP/IP to understand why, but in effect most scanning is TCP based since you can scan for SYN packets or responses.

SIP typically uses UDP which is a connectionless protocol.

it just seemed bizzare as none of the SIP ports actually showed open yet all the ports for the microsoft crap do, but she works a treat

I am loving my IP pbx though after a couple of little teething issues its run without fault or even a restart for 6 months,

What sort of PBX are you using? You clearly need to be aware of the massive security implications of leaving a PBX with port 5060 open to the internet. Unless you have good security in place it's not a case of if it will be compromised, but when.

Its lurking behind an cisco ASA 5505 on a private VLAN segmented off from the rest of the network,

and the wife has a newfoundland so if anyone gets in she'll set him onto them after she chews their ear off

Being behind an ASA with port 5060 open to the world isn't exactly any safer than having it's arse hanging out on the internet unprotected.
