Can't configure call transfer between SCCP controlled FXS ports. FXS ports are configured and registered with CCM.
stcapp ccm-group 1
stcapp call-control mode feature
voice service pots
voice service voip
dial-peer voice 103 pots
dial-peer voice 104 pots
During an active call I don't receive dial tone when pressing hookflash.
Do I need to configure telephony-service as well?
