[chan-capi-users] Sending Service Feature Fax/Speech to remote faxmachines

[Guido Hecken]

Hi list,
 
first at all thanks to the developers of chan_capi for their great channel
driver, making
Asterisk speak ISDN.
 
We are using chan_capi with bri cards from Gerdes (aka Primux ISDN).
Our involved Asterisk versions differ from 1.2 to 1.4 and baisc features
work as expected.
Chan_capi is used in Versions 1.0 and above.
 
Since we needed to integrate some analog faxmachines, we configured some 
Grandstream HT386/HT286 with the Fax Passthrough Option in the GS
Configuration interface.
While there is no problem in recieving facsimiles, sending them is only
working with remote faxmachines 
having "Faxempfang auch bei Dienstmerkmal Sprache" (something like service
feature speech ?) activated.
 
Is there any option, we can use in the available capicommands to send this
required service feature to the remote
faxmachine, or is it Grandstream's job to do so?
 
BTW we also tried Patton/Inalp's M-ATAs since we had good experiences with
their ISDN-Gateways.
But after hours of trial and error, a lack of fundet documentation and not
at least a not 
responding tech-support, we gave up.
The Grandstreams seemed to be better than their reputation and worked "out
of the box".
 

Kind regards,

Guido
