DAHDI - ISDN PRI - Sangoma

Hi

I actually have an asterisk box, with Sangoma A108 card, connected to a french E1 line. Everything’s okay for basic calls, DTMF…

I want to be able to send the ISDN commands for call parking, threeway etc to my provider.

I don’t want asterisk to do it (it’s working very well by the way), I want to use my provider’s services !

If possible i want to trigger it from SIP.

So my wuestion are :
Is there some asteirsk dialplan command that can help me trigerring those ISDN commands (like capicommmand for chan-capi) ?
Is there a mapping between some SIP info message and ISDN commands (like for the flash) ?

Best regards,

hi:
I do not think it can be done.
