Dear All

We have sip line DiD/DoD from PSTN (Telecom Comp.) ,

Call manger V 7.1 , the PSTN using huawei with codec G7.11 Aluw

most of the range working fine , but there are some number wich is analog end point local number, when i call them after they pick up the call , the call immediately disconnects ,

In debug , Previous Disconnect Cause=0, Disconnect Cause=1
ccCallDisconnect:
   Cause Value=1, Call Entry(Disconnect Cause=1)

then

Cause Value=16, Tag=0x0, Call Entry(Previous Disconnect Cause=0, Disconnect Cause=16)

then

   Cause Value=16, Tag=0x0, Call Entry(Previous Disconnect Cause=0, Disconnect Cause=0)

then

Cause Value=41, Tag=0x0, Call Entry(Previous Disconnect Cause=0, Disconnect Cause=0)

Any one have idea can help me

Hello,

Please refer this document for disconnect cause codes & its description:

http://www.cisco.com/c/en/us/td/docs/ios/voice/monitor/configuration/guide/12_4/vt_12_4_book/vt_ccodes_debug.html#wp1007443

it would be good if you could post your gateway configuration with following debugs for a test call.

- debug ccsip message

- debug voice ccapi inout

please include calling/called party numbers
