Hi all. I have an issue with T.38 and re-invites. Topology: provider -> A (asterisk 1.6) -> B (asterisk 1.6) -> extension -> -> (software fax, gateway whatever). When between A and B trunk is canreinvite=no everything is working smooth. When I switch canreinvite to yes, it stop working. Do you have any idea where the issue can be? Any help will be much appreciated. Marek Soha

'canreinvite' controls whether Asterisk is allowed to setup a direct media path between endpoints, or must keep the media flowing through itself. If you don't need a direct media path, don't enable 'canreinvite' (which in Asterisk 1.8 has been renamed to avoid this confusion). If you do need a direct media path, you'll have a problem, because Asterisk cannot currently setup UDPTL (T.38) direct media paths, only RTP direct media paths. -- Kevin P.

Does it matter? Phones are working correctly...I tried also portforwarding. So corrected topology: provider -> A (asterisk 1.6) -> B (asterisk 1.6) -> extension -> -> NAT/FIREWALL -> (software fax, gateway whatever). Software fax ends with DIS sent, 9600Bbps Joel, d?a 11. novembra 2010 ste nap?sali: JM> NAT? Firewall?
