couldnt you set it up with the t or T options in the Dial command for calls to or from that analog station so that you could use the asterisk built in transfer command?
per features.conf

it is DTMF based so when the analog user wants to transfer and is in the middle of a call… he dials the code for blind transfer then the extension number to transfer to… no hookflash needed.

It is generally the responsibility of the ATA to convert flash (time break recall) based sequences from the analogue phone into SIP REFERs.

hi david , finally i could solve the issue ,

i just updated the firmware of my ata adapter and flash line activated .

but i found the when press flash , and dial number , i have to wait untill the destination answer the call , then i close call from my side .

any way ,

thanks david very much

regards :smiley:
