Hi, I have 2 Asterisk PBX, One of them works as faxserver and another works as Gateway to PSTN (With E1), Two server are connected with sip trunk. Could i send and recieve fax with fax server?
I think this is not good way to transfer fax via sip trunk! Is it true? what about IAX trunk? Is it not wat too?
Thanks.with regards.

For faxing PSTN (based asterisk server) is always a better choice to go with !

However SIP (the other server) also not is bad if it met following.

1. Low latency / distance from termination / PSTN server
2. Using G711 codec for trunking with PSTN server
