Detailed Config :
DETAILED STEPS
| | Command or Action | Purpose |
|---|
Step 1 | enable Example: Router> enable | Enables privileged EXEC mode. •Enter your password if prompted. |
Step 2 | configure terminal Example: Router# configure terminal | Enters global configuration mode. |
Step 3 | voice register global Example: Router(config)# voice register global | Enters voice register global configuration mode. |
Step 4 | authenticate realm string Example: Router(config-register-global)# authenticate realm xxxxx | •realm string—Realm parameter for challenge and response as specified in RFC 2617 is authenticated. |
Step 5 | exit Example: Router(config-register-global)# exit | Exits voice register global configuration mode. |
Step 6 | voice service {voip | voatm} Example: Router(config)# voice service voip | Enters voice-service configuration mode to specify a voice encapsulation type. •voip—Specifies Voice over IP (VoIP) parameters. •voatm—Specifies Voice over ATM (VoATM) parameters. |
Step 7 | allow-connections from-type to to-type Example: Router(config-voi-serv)# allow-connections sip to sip | Allows connections between specific types of endpoints in a VoIP network. •from-type—Originating endpoint type. The following choices are valid: –sip—Session Interface Protocol. •to—Indicates that the argument that follows is the connection target. •to-type—Terminating endpoint type. The following choices are valid: –sip—Session Interface Protocol. |
Step 8 | fax protocol t38 [ls_redundancy value [hs_redundancy value]] [fallback {cisco | none | pass-through {g711ulaw | g711alaw}}] Example: Router(config-voi-serv)# fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback pass-through g711ulaw | Specifies the global default ITU-T T.38 standard fax protocol to be used for all VoIP dial peers. •ls_redundancy value— (Optional) (T.38 fax relay only) Specifies the number of redundant T.38 fax packets to be sent for the low-speed V.21-based T.30 fax machine protocol. Range varies by platform from 0 (no redundancy) to 5 or 7. Default is 0. •hs_redundancy value— (Optional) (T.38 fax relay only) Specifies the number of redundant T.38 fax packets to be sent for high-speed V.17, V.27, and V.29 T.4 or T.6 fax machine image data. Range varies by platform from 0 (no redundancy) to 2 or 3. Default is 0. •fallback—(Optional) A fallback mode is used to transfer a fax across a VoIP network if T.38 fax relay could not be successfully negotiated at the time of the fax transfer. •pass-through—(Optional) The fax stream uses one of the following high-bandwidth codecs: –g711ulaw—Uses the G.711 u-law codec. –g711alaw—Uses the G.711 a-law codec. |
Step 9 | exit Example: Router(config-voi-serv)# exit | Exits voice-service configuration mode. |
Step 10 | voice register pool pool-tag Example: Router(config)# voice register pool 11 | Enters voice register pool configuration mode to set phone-specific parameters for a Cisco Unified SIP phone in Cisco Unified CME. •pool-tag—Unique number assigned to the pool. Range: 1 to 100. |
Step 11 | id mac address Example: Router(config-register-pool)# id mac 93FE.12D8.2301 | Identifies a locally available Cisco Unified SIP IP phone. •mac address—Identifies the MAC address of a particular Cisco Unified SIP IP phone. |
Step 12 | type phone-type Example: Router(config-register-pool)# type ATA-187 | Defines a phone type for the SIP phone being configured. |
Step 13 | ata-ivr-pwd password Example: Router(config-register-pool)# ata-ivr-pwd 1234 | (Optional) Defines a password to access interactive voice response (IVR) and change the default phone settings on Cisco Analog Telephone Adaptors. •password—Four-digit or five-digit string to be used as password to access IVR. Password string must contain numbers 0 to 9. |
Step 14 | session-transport {tcp | udp} Example: Router(config-register-pool)# session-transport tcp | (Optional) Specifies the transport layer protocol that a Cisco Unified SIP IP phone uses to connect to Cisco Unified CME. •tcp—Transmission Control Protocol (TCP) is used. •udp—User Datagram Protocol (UDP) is used. This is the default. |
Step 15 | number tag dn dn-tag Example: Router(config-register-pool)# number 1 dn 33 | Indicates the E.164 phone numbers that the registrar permits to handle the Register message from the Cisco Unified SIP IP phone. •tag—Identifies the telephone number when there are multiple number commands. Range: 1 to 10. •dn dn-tag—Identifies the directory number tag for this phone number as defined by the voice register dn command. Range: 1 to 150. |
Step 16 | username username [password password] Example: Router(config-register-pool)# username ata112 password cisco | Assigns an authentication credential to a phone user so that the SIP phone can register in Cisco Unified CME. •username—Username of the local Cisco IP phone user. Default: Admin. •password—Enables password for the Cisco IP phone user. •password—Password string. |
Step 17 | codec codec-type [bytes] Example: Router(config-register-pool)# codec g711ulaw | Specifies the codec to be used when setting up a call for a SIP phone or group of SIP phones in Cisco Unified CME. •codec-type—Preferred codec; values are as follows: –g711alaw—G.711 A-law 64K bps. –g711ulaw—G.711 micro-law 64K bps. –g722r64—G.722-64K at 64K bps. –g729r8—G.729 8K bps (default). –ilbc—internet Low Bitrate Codec (iLBC) at 13,330 bps or 15,200 bps. |
Step 18 | end Example: Router(config-register-pool)# end | Exits to privileged EXEC mode. |
