IP Phone ==VLAN 422=== Router ==VLAN 426===CCME Router
Here’s “why” ,”how”, “What happens if” to the commands used in SIP Phone Registration to CCME.
voice service voip
allow-connections h323 to sip
allow-connections sip to h323
allow-connections sip to sip
#### SIP Phones create Voip Dial-peers. so for SIP to SIP, SIP to H323 you need to allow the connections. SCCP phones create EFXS POTS dial-peer. By Default IP-IP call is blocked)(Random Fact).
fax protocol pass-through g711ulaw
modem passthrough nse codec g711ulaw
sip
bind control source-interface FastEthernet0/0.426
bind media source-interface FastEthernet0/0.426
### Bind Control and media to the interface with the same IP Address on source-address x.x.x.x . Else you will run into problems when you try to register Phones over a Layer 3 Link.
registrar server
### Needed for phone to register
voice register global
mode cme
### Change mode to CME
source-address 14.160.126.77 port 5060
### Should be the same as bind control and media when you have InterVLAN Routing
max-dn 10
max-pool 10
authenticate register
### Needed for the phone to authenticate with username password, in intervlan registeration setup
tftp-path flash:
### All the config files for the phones will be stored here.
create profile sync 0174426467043125
### Make sure you enter this command everytime you make some changes.!!!!!! Very IMP!
voice register dn 1
number 1234
### DN for the Phone
voice register pool 1
id mac 0023.5E17.D275
### Mac Address of the Phone trying to register. Which won’t be used an authentication method when registering in Intervlan register scenario
type 7942
### Make sure you have this in here.! Else SEP<MAC-ADDRESS>.config wouldn’t be created.
number 1 dn 1
### Assigning 1234 to line 1 on the phone
username cisco password cisco
### Credentials the phone uses when it tries to register in case of intervlan.
