Play wave to caller (clock rate?)

[tine@xxxxxx (Tine Uršič)]

Hi.

I'm having a bit of trouble with playing a wave audio file to caller 
while "on hold".

*The error returned by pjsua_conf_connect is "220161"* (Incompatible 
clock rate - PJMEDIA_ENCCLOCKRATE).
The manual states: "WAV player port supports for reading WAV file with 
uncompressed 16 bit PCM format or compressed G.711 A-law/U-law format.".
I've tried a lot of different wave formats (including 16bit 8khz 
standard) and I can't seem to find the right wave settings.
If I connect player to the local speaker it works just fine (example: 
pjsua_conf_connect(pjsua_player_get_conf_port(player_id), 0); ).

I'm using pjsip v1.6 on a symbian S60 device (VAS).

How can I find which clock rate to use?

Here's my sample code:

    pj_status_t status ;
    pjsua_call_info     CallDetails ;
    pjsua_player_id     player_id;

    if (pjsua_call_get_info(CallID, &CallDetails) == PJ_SUCCESS)
    {
        //disconnect caller
        pjsua_conf_disconnect(CallDetails.conf_slot, 0) ;
        pjsua_conf_disconnect(0, CallDetails.conf_slot) ;

        //create player
        pj_str_t awav = pj_str ("C:\\Data\\OnHold.wav");
        status = pjsua_player_create(&awav, 0, &player_id);
        if (status != PJ_SUCCESS)
        {
            status = 
pjsua_conf_connect(pjsua_player_get_conf_port(player_id), 
CallDetails.conf_slot);                
            ...
        }
   
    }
