[Asterisk-Users] RTP and NAT

[WPJ mail]

I understand that setting "canreinvite = yes" in sip.conf allows clients to send RTP streams directly to each other and this works only if there is no NAT involved. But if I want to use two SIP phones behind firewalls and using NAT to be able to send RTP packets to each other bypassing Asterisk, is there a way to do that?
Can this be done if I used IAX instead of SIP? What exactly does the "notransfer" option in iax.conf do?

Thanks in advance.

Mitul
