Hi,
I have trouble making call waiting. When phone A is connected to phone B and phone C calls phone A. A receives the waiting call and C disconnects, A cannot hear from B anymore. But B still heard side A speak.
My log:
+XCALLSTAT: 1,0

+XCALLSTAT: 2,5

+CCWA: “0948971966”,129,1,0
Send AT command: AT+CLCC

+CLCC: 1,1,0,0,0,“0931105255”,129

+CLCC: 2,1,5,0,0,“0948971966”,129

OK

+XCALLSTAT: 1,0

+XCALLSTAT: 2,6

NO CARRIER

Hi vudinhnam,

Which firmware version are you using? If you are not in the latest firmware, please download the latest one (5.5.25.0) and retry.

Hi @vudinhnam

It is known issue. Sierra is aware of this issue. It will be resolved in a future release of the HL8548 firmware.
