ISDN PRI T1/E1Setup and Configuration - Cisco

I have put together this video in hopes to compile lots of information, that I feel is hard to find, all in one place and in a step by step format. **NOTE** Make sure to apply the correct codecs to your incoming dial-peers. I could not make outgoing calls from a PRI I setup in another office because I forgot to apply codecs to my incoming dial-peers EXAMPLE: Voice Class Codec 1 codec preference 1 g711ulaw codec preference 2 g729br8 codec preference 3 g729r8 TO APPLY CODECS TO DIAL PEERS conf t dial-peer voice 200 voip voice-class codec 1 Router - 2911 IOS Version - 15.4 (3) M1 In the video I mentioned framing and linecode. I forgot to add those in the video so I will put them in detail below: EXAMPLE: Router(config)#controller t1 1/0 Router(config-controller)#framing esf Router(config-controller)#clock source line Router(config-controller)#linecode b8zs or for an E1 Router(config)#controller t1 1/0 Router(config-controller)#framing crc4 Router(config-controller)#clock source line Router(config-controller)#linecode hdb3 I believe that for the E1 the framing and linecode values are the defaults. Another thing I forgot to mention is to add a source address. EXAMPLE: interface Loopback0 ip address X.X.X.X 255.255.255.255 h323-gateway voip bind srcaddr X.X.X.X This command is to indicate the address to be used as the source IP address for the gateway. Using a Loopback interface is preferable for redundancy but an Ethernet interface can be used **HELPFUL LINKS** http://www.cisco.com/c/en/us/td/docs/... http://www.cisco.com/c/en/us/td/docs/... http://www.cisco.com/c/en/us/td/docs/...
