How to answer incoming call? telephone.answer not working

I'm using 1.4.1 final on an E50.

I'd like to use telephone.incoming_call() and telephone.answer() to answer an incoming call. The documentation says:

[quote]
incoming call()
Wait for incoming call, returns immediately. If a call arrives, answer can be called to answer the call. Without the invocation of function incoming call, the function answer has no effect.

answer()
Answers an incoming call - see also incoming call.
[/quote]

My app looks like this
[code]
import appuifw
import e32
import telephone

STATES = {telephone.EStatusUnknown: "unknown",
telephone.EStatusIdle: "idle",
telephone.EStatusDialling: "dialing",
telephone.EStatusRinging: "ringing",
telephone.EStatusAnswering: "answering",
telephone.EStatusConnecting: "connecting",
telephone.EStatusConnected: "connected",
telephone.EStatusReconnectPending: "reconnect pending",
telephone.EStatusDisconnecting: "disconnecting",
telephone.EStatusHold: "hold",
telephone.EStatusTransferring: "transferring",
telephone.EStatusTransferAlerting: "transfer alerting"};

def handleCall((callState, number)):
print "callState = "+STATES[callState]

if callState == telephone.EStatusRinging:
if number == "":
print "incoming call"
else:
print "call from "+number
telephone.answer()
elif callState == telephone.EStatusAnswering:
print "hanging up"
telephone.hang_up()
elif callState == telephone.EStatusDisconnecting:
print "hung up"

def quit():
app_lock.signal()

appuifw.app.exit_key_handler = quit

app_lock=e32.Ao_lock()

old_title = appuifw.app.title
appuifw.app.title = u"Incoming"

telephone.incoming_call()
telephone.call_state(handleCall)

print "waiting for a call"

app_lock.wait()
appuifw.app.title = old_title
[/code]

When a call comes in I see this in the console:

[quote]
waiting for a call
callState = ringing
incoming call
[/quote]
[i](caller hangs up after 3 rings - the app did not answer the call)[/i]
[quote]
callState = disconnecting
hung up
callState = idle
[/quote]

The call to telephone.answer() seems to have no effect. I have also tried calling it in other spots: before and after the call to telephone.call_state() and in the ringing case in handleCall. Has anyone else gotten telephone.answer() (or incoming_call()) to work?

Thanks.

Hi - no idea if this still requires an answer :-)
but I just added some sleeps around the answer and it seems to work fine - maybe was trying to answer too quick ?

[code]
else: print "call from "+number
e32.ao_sleep(1)
telephone.answer()
e32.ao_sleep(10)
[/code]

Thanks to you both for your replies. The calls to e32.ao_sleep(1) fixed the problem - thanks, ceejay.

The new problem is that after my program answers the incoming call, it hangs: no keys have any effect. I have to remove the battery to exit the program (and all programs :-)).

There shouldn't be a need to add any sleeps to call answering, you might want to send a bug report on this to SourceForge (if there is a need for the sleeps, this should be at least documented to the API - thanks to ceejay for finding this out).

The latter problem is worth while checking also, please include firmware information should you file a bug report on this. Unfortunately that is most probably something that we can't fix - rather the fix needs to be in firmware.

Thanks in advance.

The calls to e32.ao_sleep(1) fixed the problem - thanks,

But the as soon as the Python code answer the incoming call.
The script quite.

Is there a way for the Python script to stay at background?

Hi

I'm using the original code in this thread plus the sugested e32.ao_sleep() calls but as soon as a call is received the phone reboots.


I'm using Nokia 6120classic 3rd edition, FP1


Since the original thread is very old, I'm suspecting some incompatibility.


Any ideas, anyone?

Hi carlosl,
although this thread is very old but the script given here is perfectly working. I had tried it on n95. Even telephone.Answer is working fine without any issue.
