If yes, please help me out. After configuring extension.conf and modem.conf I could make outward calls correctly from gnophone and kphone. Still the inward call to the configured MSN is correctly reaching Asterisk and also to the configured Context. But the issue is, it was hanging on 'Answer' application and throwing out 'Unable to Spawn Extension (vpk, s, 1) ..... ". When I debug, found that Asterisk is issuing the following AT commands while answering the call. ATA (expecting VCON ) AT+VRX+VTX (expecting CONNECT ) In the above sequence, I found that after giving ATA, without waiting for VCON it is giving the AT+VRX+VTX command and getting CONNECT successfully, but according to voice communication CONNECT without VCON would fail and hanging up the line. Though all the above things are my Points on debugging, my basic issue is to successfully ANSWER an incoming call. Please throw some lights. Regards Murali Krishnan.S <ismk@myrealbox.com>
