Dear ,
Please check the below configuration it should be working with SIP phones
voice service voip

 allow-connections sip to h323
 allow-connections sip to sip
 sip
  registrar server expires max 600 min 60
voice register global
 system message SRST Active
 max-dn 50
 max-pool 19
voice register pool  1
 id network xx.xx.xx.xx mask xx.xx.xx.xx
 dtmf-relay rtp-nte cisco-rtp sip-notify
 codec g711ulaw
 no vad
sip-ua 
 registrar ipv4:yy.yy.yy.yy expires 600
On UCM SRST reference configuration for gateway
SIP Network/IP Address : yy.yy.yy.yy

for xx.xx.xx.xx insert the network ID
for yy.yy.yy.yy insert Gateway IP
