Hello, I have been fiddling around with voice calls on my WP8548. Unfortunately, I got only as far as unlocking my (non-M2M) SIM and registering to the network: (See SIM / Network info below) At the callback: LE\_CELLNET\_REG\_HOME, (in response of [color=#008000]le\_cellnet\_Request()[/color]) I tried setting up a voice call via the [le\_mcc\_interface.h](http://legato.io/legato-docs/latest/le __mcc__ interface_8h.html) as in the [sample](http://legato.io/legato-docs/latest/c_mcc_test.html) which [color=#FF0000]failed[/color], as well as via the [le\_voicecall\_interface.h](http://legato.io/legato-docs/latest/le __voicecall__ interface_8h.html) Both returned similar results: [quote]Jan 6 06:49:05 | INFO | antennatestprogram[1068]/AntennaTestProgramComponent T=main | AntennaTestProgram.c \_AntennaTestProgramComponent\_COMPONENT\_INIT() 417 | done.

Update: I tried downgrading to release [color=#000040]SWI9X15Y 7.0 Release 7[/color], in which the old audio code still works. SUCCESS! 😃 ```auto > ATS0=1 //set automatic answering after 1 'RING' /*Called the SIM phone number...*/ > RING //incoming call /*Automatic pick up of phone call!!*/ ``` Note: I could only downgrade a module with PRI Part Number: 9904889 But I need to test voice call on a module with PRI Part Number: 9905383 =\> possible solution: try downgrading to [color=#000040]SWI9X15Y 7.0 Release 8[/color]. =\> Unfortunately, these download links are down: [ol] [li]Carrier Configurations: [url][http://downloads.sierrawireless.com/legato/1510/wp85/9999999\_9904559\_SWI9X15Y\_07.05.01.00\_00\_GENERIC\_001.013\_000-field.exe[/url][/li]](http://downloads.sierrawireless.com/legato/1510/wp85/9999999_9904559_SWI9X15Y_07.05.01.00_00_GENERIC_001.013_000-field.exe%5B/url%5D%5B/li%5D) [li] Legato: [url][http://downloads.sierrawireless.com/legato/1510/wp85/legato-15.10.1.exe[/url][/li][/ol]](http://downloads.sierrawireless.com/legato/1510/wp85/legato-15.10.1.exe%5B/url%5D%5B/li%5D%5B/ol%5D) Any alternative download links for these? ---
