Hi,
I'm trying to get sip srst working and must be missing something very simple.
This is the config I've got:
voice service voip
ip address trusted list
ipv4 85.119.63.4
ipv4 10.26.120.129
ipv4 10.26.120.0 255.255.255.0
address-hiding
allow-connections sip to sip
redirect ip2ip
fax protocol t38 version 0 ls-redundancy 0 hs-redundancy 0 fallback none
sip
bind control source-interface GigabitEthernet0/1
bind media source-interface GigabitEthernet0/1
registrar server
asserted-id pai
midcall-signaling passthru
pass-thru content sdp
sip-profiles 1
!
voice class codec 711
codec preference 1 g711ulaw
codec preference 2 g711alaw
codec preference 3 g729r8 bytes 30
voice register global
system message *** SRST in Action ***
max-dn 56
max-pool 10
!
voice register pool 1
id network 10.26.120.0 mask 255.255.255.0
preference 2
proxy 10.26.120.129 preference 1
dtmf-relay rtp-nte
voice-class codec 711
As far as the router is concerned the phones are registering:

However, the phones themselves just sit there with the message : Registering and blank screen.
Any ideas?
Thanks

Did you check if the phone has the SRST reference? At the phone Go to Setting -->Device Configuration --> Unified CM Configuration--> SRST: IP?

Yep - 2nd server is the SRST gateway
CUCM Server1 | 10.26.120.129 Active | |
CUCM Server2 | 10.26.120.148 Standby |

Your proxy is the IP address of the CUCM server then, it needs to be the local SRST GW.
