Does anyone know if 2talk allow incoming SIP URI calls to their platform?

And if so, what is the URI format. I tried <number>@2talk.co.nz but that didn't seem to work.

Can't your PBX take an incoming SIP call?

Not running one. My IP phone at home registers direct to 2talk.

What about port forwarding SIP to your phone and running your own domain then?

Well I already run the domain, but not sure that the phone (Siemens Gigaset) would receive an inbound URI call?

SIP URI calling is a massive security risk these days. Everybody out there with a SIP device that has 5060 port forwarded will realise this when there phone keeps ringing randomly in the middle of the night..

Only allowing SIP access from your SIP proxy. Cisco/Linksys devices have an option called "restrict source IP", but this apparently doesn't work with 2talk.

Assume you can whitelist IPs in Asterisk? Maybe time to put that Raspberry Pi to good use

Just out of curiosity... Why would that happen?





Sometimes what you don't get is a blessing in disguise!

Because there are bots out there continually trying brute force SIP attacks. Unless you're fully aware of the implications and have adequate security policies in place you should never expose any SIP devices directly to the internet.

The other issue with not using something such as Restrict Source IP is that these bots will use your traffic allowance. I had some dealings with an iTalk customer a few months ago who had used several GB over the course of a week, all of which was a bot running a 24/7 attack against their Linksys VoIP router.

Hi, 

This is probably best suited in the VoIP section, 2Talk are a completely seperate company from Slingshot. 

Cheers,
