We would like to get a few SIP trunks for our PIAF box and have looked at sip.us. Our main concern though is that on your firewall you have to leave RTP ports open to the internet at large.
At least that is what they are saying on their website.
I can lock down UDP-5060 and allow traffic only from sip.us domain name, so that is good.
With RTP I can't do that they say, cause they release the media on all calls to the closest carrier media gateway.
Now what are the implications of that in terms of security.
Potential DoS attacks?
More?
Thanks.
