[asterisk-users] sip:EXTEN;phone-context in asterisk dial plan

[ast guy]

Hi,

 Can any one please guide how do I handle the SIP phone-context URI
parameter. I got following traces..

  9.191690  IP_A -> IP_B  SIP/SDP Request: INVITE
sip:12599;phone-context=private at IP_B:5060;user=phone, with session
description
  9.191942  IP_B -> IP_A  SIP Status: 404 Not Found
  9.195656  IP_A -> IP_B  SIP Request: ACK
sip:12599;phone-context=private at IP_B:5060;user=phone


I have 12599 defined extension under [default] context. but still
getting 404 not found...
What changes I require in sip.conf or extension.conf files. Even I
defined the extension in [private] context but still it was not
working.
