srst for sip phones

[Giancarlo Evangelista]

Good morning, I'm trying to configure the SRST for sip phones.

I've configured srst  on CUCM side, and the following there is a configuration on the router:

!
voice class codec 1
 codec preference 1 g711ulaw
 codec preference 2 g711alaw
 codec preference 3 g729r8
!

voice register global
 mode srst
 max-dn 100
 max-pool 50
 dialplan-pattern 1 0039880077311 extension-length 3 extension-pattern 814
 dialplan-pattern 2 003988007731.. extension-length 3 extension-pattern 8..
!
voice register pool  1
 id network 192.168.2.0 mask 255.255.255.0
 dtmf-relay rtp-nte sip-kpml
 voice-class codec 1
!

It's correct  or need to configure somethings other?
