Hi,

i have bad results with efax->t38modem->chan_ooh323->res_fax->chan_sip
(t38 disabled, alaw codec). Sending side is efax, receiving side is sip
remote side. 
When receiving side answers i see next messages:

[May  9 15:17:50] VERBOSE[4157] chan_ooh323.c: +++++ ooh323_queryoption 10
on channel OOH323/telecore-2

[May  9 15:17:50] VERBOSE[4157] chan_ooh323.c: ----- ooh323_queryoption 10
on channel OOH323/telecore-2

Then there is a lot of queryoption messages:


[May  9 15:17:52] VERBOSE[4157] chan_ooh323.c: +++++ ooh323_queryoption 10
on channel OOH323/telecore-2
[May  9 15:17:52] VERBOSE[4157] chan_ooh323.c: ----- ooh323_queryoption 10
on channel OOH323/telecore-2
[May  9 15:17:52] VERBOSE[4157] chan_ooh323.c: +++++ ooh323_queryoption 10
on channel OOH323/telecore-2
[May  9 15:17:52] VERBOSE[4157] chan_ooh323.c: ----- ooh323_queryoption 10
on channel OOH323/telecore-2

so it's like to infinite loop.
10 is AST_OPTION_T38_STATE and ooh323_queryiotion return 4,
T38_STATE_NEGOTIATED


When asnwering side hang up see messages:
