<br class="">
So Telstra mobile services increasingly seem to revert to using<br class="">
Wifi calling even in the presence of decent signal strength.<br class="">
<br class="">
If I were a CDN wanting to connect to Telstra IP,<br class="">
they'd charge me for injecting traffic into their network or for transit,<br class="">
and yet Telstra is injecting traffic into our our network to carry <br class="">
some of their cell traffic, without payment or agreement.<br class="">
<br class="">
Now you might say, sure, but we're doing that for our customers not <br class="">
for Telstra. But Telstra themselves will charge CDNs for delivering <br class="">
content<br class="">
to Telstra's customers, something Telstra's end customers are presumably<br class="">
already paying for. So yeah, we know in this industry what is good for the<br class="">
goose is not always good for the gander.<br class="">
<br class="">
Another point, Telstra, who are our sworn competitors, are using our <br class="">
network for Wifi calling to supplement their mobile network. Presumably<br class="">
this use of their competitor's networks reduces their capital investment<br class="">
requirement and supports their revenue stream by raising the<br class="">
quality of their coverage. Hence Telstra's use of their competitor's networks<br class="">
enhances their ability to dominate the industry, again without<br class="">
any kind of settlement to their competitor ISPs.<br class="">
<br class="">
Thoughts?<br class="">
<br class="">
Also, anyone have any thoughts about what ACL one might put in place<br class="">
to block wifi calling if one was of a mind to?<br class="">
