Multiparty ("3-way") Call Problem


#1

Fastrack Supreme
R74a00gg.FSU005 2106632 102809 12:57
No Open-AT application (although the same problem occurs when trying to do this programmatically in an Open-AT application)
Vodafone UK network

1. Accept an incoming call

2. Put that call on hold

3. Dial an outgoing call

4. The call fails - the called number is busy

5. The Fastrack still knows that the other call is on hold, and the held caller is still hearing the holding tone

6. How do I reconnect to the held call :question:

“add a held call to the conversation” doesn’t work

“release all active calls (if any exist) and accept the other (held or waiting) call” doesn’t work

“place all active calls (if any exist) on hold and accept the other (held or waiting) call” doesn’t work

“place all active calls on hold except call X with which communication is supported” doesn’t work

The call is still there:

:confused:

I’ve just tried this with the same SIM in a SIMCOM SIM300 module, and the held call can be reconnected with any of:
AT+CHLD=1
AT+CHLD=2
AT+CHLD=21
AT+CHLD=3


#3

and an old Siemens TC35i will reconnected the held call with either AT+CHLD=1 or AT+CHLD=2


#4

An old Fastrack M1306B will reconnected the held call with either AT+CHLD=1 or AT+CHLD=2

So this appears to be a recent SiWi bug.

Have you tried the more recent versions of firmware?? R7.45.1 was recently released.
