     49=== GSM Call Interruption Problem === #gsm 
     50 
     51If a VoIP call is in progress when an incoming GSM call arrives, and if the user accepts the GSM call, the audio routing of the phone is flawed producing the following result: The VoIP call goes to speaker and the GSM call does not “grab” the audio channels so you get a “null” GSM call and the VoIP call carries on with speaker. 
     52 
     53To prevent this from happening, application must implement GSM call detection using BB10 native API, and when it detects a GSM call, it should close PJSIP sound device by using either {{{pjsua_set_null_snd_dev()}}} or {{{pjsua_set_no_snd_dev()}}} and put the VoIP call on hold before accepting the GSM call.
