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 126.96.36.199 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.
