Hello
I have a SIMCOM508 modem connected to minicom on ubuntu.
Iam able to make calls, add, hold, wait, swap and sms except multiparty conference call.
I have followed the steps in http://www.microchip.ua/simcom/GSM-G...0Note_V1.0.pdf
to try this
The final AT+CHLD=3 returns just an ERROR from the modem.
is there any sequence to be followed doing this?
could someone help out?
Thanks
