    Check out the following link and see what you think:

    I truly missed your input
    So far as I can tell, incoming voice call notification can be acheived by:

    1. Setting AT+CRC=1 so that the phone will report an incoming voice call.
    2. Allow Phone Control to listen for +CRING:VOICE.
    This is what PhoCo uses (if the phone supports it)
    And answering the call is just as easy:

    1. The user presses an "Answer" button in Phone Control. (?)
    2. Phone Control could then trigger the command at$qccav.
    This can be achived by setting that string into the config: <Accept>$qccav</Accept>
    In testing, these commands ARE supported by my LG VX-4500. I would guess that this would also work for most other phones using Qualcomm chipsets. I'm almost certain that most (if not all) phones that are Brew compatible are based on a Qualcomm chipset.

    I also tried many of the other commands, such as the SMS messaging and CLIP commands, and those did NOT work on the LG.

    On a different note, it's also occurred to me why some people may have been having problems before. I had to force my phone's baud rate down to 38K to work with Phone Control, because I don't think Phone Control was able to recognize the faster baud rates. Most CDMA phones are set (by default) to 230K. It would be really nice however to be able to have supported baud rates that can go that high through Phone Control.
    This is not a limitation of PhoCo but of the BT-Stack (or COM connection) you use. Sometimes (e.g. on older phones) you can't use speeds beyond 19.200 Baud.
    People should also verify that their data settings are set correctly on the phone itself. I'm not certain, but some phones might require that you manually turn the data port on.

    As always Zorro, you are awesome and appreciated. I'll try to continue to get any additional information I can and help out with the CDMA side of things.

    Thanks,
    Bryan Pape
    Yeah, go for it
    I'm gratefull for your help, especially if it allows us to gain more CDMA phones

    Oops....

    Hi Zorro,

    It looks like I might have jumped the gun just a bit. The VX-4500 reports an OK status following AT+CRC=1, but does not (so far as I can tell) report incoming voice calls. I've been looking for another associated parameter that might be affecting this, but can't find one. As a result, there may be no notification. Others might want to try on their CDMA phones to see if they get different results.

    On the up side however, the answer string does definately work. As a result, I'd like to know if there's a way to activate the call button to issue AT$QCCAV during those times when it's not set to dial out (which only seems to occur when the dial pad is active AND has numbers entered).

    If Zorro can add this functionality, most CDMA phones should be able to:

    1. Dial out.
    2. Answer incoming phone calls. (Perhaps MediaPlayer volume can be muted during a manual answer (instead of ring), and unmuted during hangup).
    3. Import their phonebooks into Phone Control. (I first transferred my phonebook into Verizon's Mobile Office utility. From there exported the file, and then easily imported into Phone Control using PBConvert. BitPim is another alternative.)

    You likely won't be able to:

    1. Transfer SMS messages.
    2. Transfer the phonebook directly into phonecontrol.

    I would also encourage those using Nokia CDMA phones to try all features, because it appears as though they might include the full GSM command set.

    In further testing, I was also able to get PhoneControl to communicate at 115200 bps, which is the maximum speed that the USB->Serial adaptor can be configured for. It should be noted that the phone defaults to 230400 bps.

    Thanks again for everything Zorro,
    Bryan

    PS - Perhaps anyone who has a PBConvert template that works for a particular phone/software configuration should send it to Zorro (if he wouldn't mind ) so it can be available to others.

    I'm afraid, I don't understand what you mean. Is the AT$QCCAV doing more then dialing? Can it be put under <AdditionalInit>?

    Yes, sure... no problem with that.

    Sorry - I was a little vague. AT$QCCAV is the command to answer an incoming voice call. There needs to be a button to send the command manually to answer incoming calls since Phone Control won't be receiving notification from the phone.

    Thanks,
    Bryan

    i have an n400 and tried it with phone control. the only thing i was able to do was dial out. it did not recognize incoming calls nor could i answer the phone from within phone control when i was receiving a call. seems like there is hope from reading what bryan and zorro are posting.

    Ok But what's the point of answering it if its not gonna be speakerphone anyways? I can just pick up the phone manually, which I would have to do anyways

    Hope in that those with Qualcomm chipsets can also (with Zorro's help) answer calls through Phone Control as well, due to a newly discovered AT command.

    To make this work however, there needs to be a way to have Phone Control send the command, since there's no notification from the phone.

    Yes, but what purpose will this have? Will I be able to use the speakers as a speakerphone and a mic and the mic?

    I don't see why not. There's a headset jack on the side of the phone, which should allow you to get access to both (with a little help from Radio Shack of course).
