Request your expertise on configuring SIP SRST urgently.
This is what I configured yet.
voice service voip
allow-connections h323 to h323
allow-connections sip to sip
fax protocol pass-through g711ulaw
modem passthrough nse codec g711ulaw maximum-sessions 2
sip
registrar server expires max 1200 min 60
!
voice class codec 1
codec preference 2 g711ulaw
codec preference 3 g729r8
!
voice class h323 1
h225 timeout tcp establish 3
!
!
voice register global
timeouts interdigit 5
system message "SRST Mode"
max-dn 50
max-pool 50
!
voice register pool 1
id mac 5067.AEE3.6CC6
number 1 2404
dtmf-relay rtp-nte
voice-class codec 1
Do I need to point GW ip and port 5060 in register global?
This is not CME.
Please help.

Couple of things:
Under register pool 1 you may want to add "id network"
what is the version of IOS? You may need to add "ip address trusted" under voice service voip
In CUCM you definitely need to ensure the phone's DP has proper SRST defined.
What do you see when you run "debug ccsip messages"?

Phones have registered.
Only issue is the system message that I configured under voice register global is not appearing on the SIP phones..
Please help me resolve this.

There are few things i realized while doing the SIP SRST.
Voice service voip
ip address trusted list
IPV4: <IP subnet matching the dhcp scope> mask <mask>
Sip
registrar server expires max 600 min 60
voice register global
system message "SRST Active"
max-dn 100
max-pool 2
timezone XX
voice register pool 1
id network <IP subnet matching the dhcp scope> mask 255.255.255.0
proxy <Gateway Loop back IP>
num-exp XXXXX YYYYYY... (Short dial within site)
sip-ua
registrar 1 ipv4:<Gateway Loopback ip> expires 3600
Call manager-fallback
System message Primary SRST Active
Make sure the SRST reference is defined with the ip and port for SIP, and is added to the Device pool.

If I can just revive this after the fact:
Our requirement was to have specific phones allocated a different cor list - only only available is to use static IP Assignment - really, thanks for nothing Cisco! :(
