Now i make this changes, dahdi was recompilled
dahdi_dynamic.c
z->chans[x]->sigcap = DAHDI_SIG_EM | DAHDI_SIG_CLEAR | DAHDI_SIG_FXSLS |
DAHDI_SIG_FXSKS | DAHDI_SIG_FXSGS
| DAHDI_SIG_FXOLS |
DAHDI_SIG_FXOKS | DAHDI_SIG_FXOGS
| DAHDI_SIG_SF |
/* DAHDI_SIG_DACS_RBS |
DAHDI_SIG_CAS;*/
/* peter enable dahdi mtp2 for
tdmoe */
DAHDI_SIG_DACS_RBS |
DAHDI_SIG_CAS | DAHDI_SIG_MTP2;
and
in system.conf i change dchan with mtp2 and everithing looks great - no
errors, no debug messages,
just circuits in idle condition.
We will see how stable will be the redfone + tdmoe + mtp2
Have a nice day everyone!
Regards,
Peter
