Has anyone once achieved thsi? We are trying to connect the CME SIP trunk ( 12.4.22T advipservices ) on a 2811 to a VX900 We can call from SIP phone registered on VX to phone registered on cisco CME but not back so it looks like a dial-peer issue though I can't think of anything . There is no dial tone on SIP phone at CME ( SPA922 )   Any suggestions?   Here is our config:   voice service voip  allow-connections sip to sip  sip   registrar server expires max 600 min 60 ! ! voice class codec 1  codec preference 1 g729br8  codec preference 2 g729r8  codec preference 3 g711alaw ! voice register global  mode cme  source-address xx.xx.xx.xx port 5060  max-dn 8  max-pool 8  authenticate register  dialplan-pattern 2 690.... extension-length 4  tftp-path flash:  create profile sync 0007272453516527 ! voice register dn  1  number 6902222  allow watch  !  voice register pool  1  id mac [mac-address of client]  type 7970  dtmf-relay sip-notify  voice-class codec 1  username xxxx password xxxxx !  dial-peer voice 1 voip  description ** SIP TRUNK **  destination-pattern 686....  voice-class codec 1  voice-class sip dtmf-relay force rtp-nte  session protocol sipv2  session target ipv4:[IP of remote VX SIP server]  dtmf-relay rtp-nte  no vad   ! telephony-service  em logout 0:0 0:0 0:0  max-ephones 10  max-dn 20  ip source-address xx.xx.xx.xx port 2000  load 7960-7940 P00308000500  dialplan-pattern 1 690.... extension-length 4  max-conferences 8 gain -6  transfer-system full-consult  create cnf-files version-stamp Jan 01 2002 00:00:00 !
