[asterisk-bugs] [JIRA] (ASTERISK-22842) V29 is incompatible with minrate setting 2400

Paolo Compagnini commented on ASTERISK-22842:
---------------------------------------------

I am not 100% sure but it seems that it doens't makes sense to check the minrate at that point/state at least.

I agree that minrate=2400 cannot be used because none of the selected modems support that rate. But res_fax should select/use the next possible higher rate when communicating to the remote fax machine. 

I didn't check how res_fax selects the rate in a fax call, but this could simplify the code and help the users.
If you take a lot how a normal user will lokk at this... since 2400  < 9600 why should't it work.

>          Components: Resources/res_fax
>    Affects Versions: 1.8.14.0

> Get the following error:
> ERROR[8432]: res_fax.c:2086 sendfax_exec: 'modems' setting 'V29' is incompatible with 'minrate' setting 2400
> I am using default options in res_fax.conf:
> minrate = 2400
> modems = V17,V27,V29
> When i put in dialplan FAXOPT(modem)=V29 to force using V29 (because V17 is not able to send with 9600baud), then i get the error above. Does this mean if the default order is V17,V27,V29 then V29 can never be used because the min bitrate is always to low?
> And why is V29 then not using bounds of maxrate?
