Cisco. How to organize an emergency call through pots?

Question

Telephony

Hello everybody.
There is an operator voip (mtt) and pots (mgts). It turned out that MTT does not provide access to calling emergency services, so calls to the number ^91 .. must be sent through MTS.
Tell me, in which direction to read the manuals? Do it through cor list? Or translation-rule?
Phone config example:

voice register pool 2
id mac 5C50.15A8.ECD9
session-transport tcp
type 9971
number 1 dn 22
cor incoming class3 default
dialplan 1
presence call-list
dtmf-relay cisco-rtp
username 113 password 113
no vad

class3:

dial-peer cor list class3
member internal
member moscow
member cell
member free

And deal-peer moscow:

dial-peer voice 201 voip
corlist outgoing moscow
translation-profile outgoing no0outbsip
preference 1
destination-pattern ^9749[59].......$
session protocol sipv2
session target ipv4:xxx.xxx.xxx.xxx
session transport udp
voice-class codec 1
dtmf-relay rtp-nte
fax rate 14400
fax nsf 000000
fax protocol t38 version 0 ls-redundancy 0 hs-redundancy 0 fallback none
no vad

And here are the deal-peer pots:

dial-peer voice 553 pots
trunkgroup pstn4-int 1
corlist outgoing pstn4-int
destination-pattern ^91..$
forward-digits 3
no register e164
no sip-register

Thank you!
