Hi, I am using asterisk 1.4 version with libss7 and dadhi. I am trying to dial a extension connected in Nokia Siemens PBX from asterisk soft phone. But I get the error as below in asterisk console DAHDI/1-1 is proceeding passing it to SIP/5060-b7519f08 -- DAHDI/1-1 is making progress passing it to SIP/5060-b7519f08 -- DAHDI/1-1 is making progress passing it to SIP/5060-b7519f08 [Mar 26 17:41:26] ERROR[7175]: chan_dahdi.c:10059 dahdi_ss7_error: !! Unable to handle message of type 0x3 on CIC 1 -- Hungup 'DAHDI/1-1' == Everyone is busy/congested at this time (1:0/0/1) -- Auto fallthrough, channel 'SIP/5060-b7519f08' status is 'CHANUNAVAIL' The connectivity between the Nokia Siemens PBX to the Asterisk is a SS7 connectivity. In that SS7connectivity Inbound is working fine , the traffic from Nokia siemens to asterisk is working but the traffic from asterisk to Nokia Siemens is not working ended with the above error message. Is there any option I need to check. Or is this any oubound privileges to be enabled in the SS7 link? Please suggest me. -- Thank you with regards, Gopal, PeopleTech Systems Private Limited www.peopletech.co.in -------------- next part -------------- An HTML attachment was scrubbed...
