IIUC Notes - More Phone Features

Here are some more notes from my IIUC studies.  As always, corrections requested.

• Broadcasts messages to a group for a one-way communication
• Paging groups are used to limit which phones get the broadcast
• Paging can be unicast or multicast
  • Unicast groups limited to 10 members
  • Multicast requires mcast support on the network
• Paging configurations can be unicast, multicast, or multiple-group

!  Unicast Paging
!  When 1044 is dialed, ephone 1 is paged
R1(config)#ephone-dn 44
R1(config-ephone-dn)#number 1044
R1(config-ephone-dn)#paging
R1(config-ephone-dn)#exit
R1(config)#ephone 1
R1(config-ephone)#paging-dn 44

!  Multicast Paging
!  When 1045 is dialed, ephone 2 is paged
R1(config)#ephone-dn 45
R1(config-ephone-dn)#number 1045
R1(config-ephone-dn)#paging ip 239.1.1.100 port 2000
R1(config-ephone-dn)#exit
R1(config)#ephone 2
R2(config)#paging-dn 45

!  Multiple Group Paging
!  When 1046 is dialed, both ephones 1 and 2 are dialed
R1(config)#ephone-dn 46
R1(config-ephone-dn)#number 1046
R1(config-ephone-dn)#paging group 44, 45

• There is a limit of 10 DNs in the paging group.

After-hours Call Blocking

• Allows you to configure time ranges and patterns that cannot be called during those ranges
• Three steps
  1. Defines days and/or hours that are considered after-hours
  2. Specify patterns to be blocked
  3. Create exemptions

R1(config)#telephony-service
R1(config-telephony)#after-hours day mon 18:00 07:00 <- afterhours = 6pm to 7am
R1(config-telephony)#after-hours day tue 18:00 07:00
R1(config-telephony)#after-hours day wed 18:00 07:00
R1(config-telephony)#after-hours day thu 18:00 07:00
R1(config-telephony)#after-hours day fri 18:00 07:00
…
R1(config-telephony)#after-hours date Dec 25 00:00 00:00 <- Christmas is after hours
…
R1(config-telephony)#after-hours block pattern 1 91900……. 7-24 <- Pattern index 1 blocks 900 numbers 7day/24hours
R1(config-telephony)#after-hours block pattern 2 91………. <- Pattern index 2 block all long distance after hours
…
R1(config-telephony)#login timeout 15 clear 18:00 <- Allows logins for entering a PIN for after-hours exemption; times out in 15 minutes and clears at 18:00
R1(config-telephony)#exit
R1(config)#ephone 1
R1(config-ephone)#after-hours exempt <- the boss's phone can call anywhere except the 7-24 patterns
R1(confg-ephone)#ephone 2
R1(config-ephone)#ping 1234 <- Your phone can log in with this PIN for after-hours access

• Phones have to be restarted or reset for the Login key to be enabled.

Call Accounting

• It's important to see who is calling international numbers every day at lunch.
• Call Detail Records (CDRs) record who called what number when for how long plus more stuff.
• CME logs CDRs to the logging buffer, syslog, or both.
• Logging buffers clear when a router loses power, but it may be better than nothing.  <- Don't do this ever!  Get a syslog server!

R1(config)#logging buffer 512000 <- Set the logging buffer size to 512000 bytes
R1(config)#dial-control-mib retain-timer 120 <- Roll records out in 120 minutes
R1(config)#dial-control-mib max-size 100 <- Only keep last 100 records

• Sending to syslog allows you to keep more records

R1(config)#gw-accounting syslog
R1(config)#logging 192.168.0.2 <- Log to this server

• Account codes are used for billing.
  • Each department or unit can enter a code that appears in the CDR for use later.
• Users press the Acct key when the call is ringing or connected to enter their code.

Music on Hold

• Do I have to explain what MoH is?
• WAV or AU file in flash
• Files must be G.711 or G.729
  • G.711 is recommended since it is of higher quality
• Can be delivered via unicast or multicast

R1(config-telephony)#moh piratedmusic.au <- Plays a local audio file as MoH
R1(config-telephony)#multicast moh 239.1.1.15 port 2001 <- multicast the MoH
