Summary:                    [patch] DAHDI bridge can't fax pass through
Description: 
iam realy suprised, why fax can't pass through inside DAHDI bridge
looking through chan_dahdi.c code
inside function dahdi_bridge
have a code
                f = ast_read(who);
                if (!f || (f->frametype == AST_FRAME_CONTROL)) {
                        *fo = f;
                        *rc = who;
                        res = AST_BRIDGE_COMPLETE;
                        goto return_from_bridge;
                }
                if (f->frametype == AST_FRAME_DTMF) {
                        if ((who == c0) && p0->pulsedial) {
                                ast_write(c1, f);
                        } else if ((who == c1) && p1->pulsedial) {
                                ast_write(c0, f);
                        } else {
                                *fo = f;
                                *rc = who;
                                res = AST_BRIDGE_COMPLETE;
                                goto return_from_bridge;
                        }
                }
                ast_frfree(f);

                /* Swap who gets priority */
                priority = !priority;

i see that only the SIGNAL FRAMES can pass
