I have a scenario that asterisk-gw is a pstn gateway.
Calls are originated from another asterisk-sbc witch he behave like SBC. He collect calls from other voip providers and he is terminating them to asterisk-gw.
voipProviders --> (SIP -g729)asterisk-SBC --> (SIP - g729)asterisk-gw (E1)--> TDM network
With calls all testing is OK. When trying to send fax there is a problem. I don't really understand how Fax for Asterisk works.
I only want faxes that are coming from internet to be terminated to pstn network. I have on asterisk-gw in 1.4.24 and i have installed Fax for asterisk with g711. When a fax is arriving then i should have from asterisk-gw a REIVITE for change of codec from g729 to g711 since is passing FAX. This is not happening. My digium PRI E1 TE122 is detecting a FAx but does not know how to handle it since in my dialplan i haven't create any fax extension.
The question is this :
Can I pass FAX from internet to pstn with the new Fax for Asterisk??
I want to try asterisk 1.6 and get some license for t38 fax channels but i need to know if this scenario is possible.
Thank you in advance for any help
