Cisco CUBE SIP Trunk

Cisco CUBE configuration requires a knowledge of setting up dial-peers that is outside the scope of this KB, but here is a sample template and documentation on how to make things mostly work. Note that anything with a preceeding dollar sign ($) indicates a variable that is specific to your environment and situation.

 

!! Standard voip setup
!!!! outbound proxy line is MANDATORY to ensure packets get to the right host 
!!!! since the registrar is yourdomain name and not a valid FQDN
!!!! also sets up t38, modem-passthrough, P-Asserted-Identity

voice service voip
  fax protocol t38 ls-redundancy 5 hs-redundancy 2 fallback pass-through g711ulaw
  h323
    call service stop
  modem passthrough nse codec g711ulaw redundancy
  sip
    rel1xx disable
    min-se  86400
     outbound-proxy dns:nms1-cos.option9.net
    no call service stop
    asserted-id pai



!!! Optional for FXS - register individual dial-peers; 
! dial-peer voice XXXXXX pots
!    port X/Y
!     authentication username $EXTENSION  password  $PASSWORD
!
!!! Optional - If using static-IP based SIP trunk, do not register dialpeers:
!! dial-peer voice XXXXXX pots
!    port X/Y
!     no sip-register



!!! Mandatory for VoIP dialpeers -- set the DTMF relay type
dial-peer voice XXXXX voip
    dtmf-relay rtp-nte



!!! SIP Trunk settings - Static
!!! Sets the appropriate domain names on the trunk for outbound dial
!!! also sets it to re-use port 5060 for connections for clean SIP Ladders
sip-ua
  registrar dns:$YOURDOMAIN expires 90
  sip-server dns:$YOURDOMAIN
  connection-reuse
  


!!! SIP Trunk Settings - Registration based
