Hi guys, Thanx a lot to all of you. My call is now forwarded to sip form PSTN, but again a new problem is coming. When i pick up the call from my softphone it says the can not access speaker or microphone. But i have my headphone plugged in and in working stage. on softphone: Fri 18:08:17 Warning: Failed to open sound card: Device or resource busy this message is displayed and on CLI -- SIP/2001-081fa758 is ringing -- Got SIP response 480 "User not responding" back from 172.26.48.113 -- SIP/2001-081fa758 is circuit-busy is displayed, even though i pick up, i can hear the ringing tone in the phone which called and not able to talk . What may be the problem. -- Nikhil Kumar summer intern:simmortel voice technologies rit2007033 b.tech IT 6th sem IIIT Allahabad contact at 9793905858 email: rit2007033 at iiita.ac.in niksinghania at gmail.com http://profile.iiita.ac.in/RIT2007033/ -------------- next part -------------- An HTML attachment was scrubbed...
