it's a media bug. it just hides in the background like fax_detect and if it hears a fax tone it turns into gateway mode. from there it can re-invite OR wait for re-invite, if no negotiation is made it will pass the audio fax across anyway. passthrough is turned on with a variable, if set everything goes on as normal (no need for proxy mode) it will pass the t38 invite both ways and if it realizes there is a t38 negotiation it will pass it. for regular termination it's just automatic, either send or wait for re-invite based on config It probably does everything and anything you want better than you think, just try it.....

You could use FreeSWITCH in proxy media or bypass media without any specific T38 support right now...

Is T38 forced on if you do this, or does it just enable the feature if it sees it in a reinvite? We have a bunch of fax lines w/ SPA2102 and then we use Cisco routers as PRI-SIP gateways. Some of the people use the lines for phone too, so I need it to support T38 and regular g711 calls. Right now we just point the SPAs direct to the Cisco gateway and it works fine, but we lose all accounting capability, voicemail, etc that we want/need.
