CUCM与Cisco2811路由器SIP集成
命令间存在逻辑关联，必须按照前后顺序进行配置。1. 配置语音编码及SIP地址格式
voice> host ipv4:CUCM的地址
voice> codec preference 1 g729r8
codec preference 2 g711ulaw
codec preference 3 g711alaw
codec preference 4 g722-64
2. 配置VOIP服务具体参数
voice service voip
ip address trusted list
ipv4 CUCM的地址 PUB
ipv4 CUCM的地址 SUB1
allow-connections h323 to h323
allow-connections h323 to sip
allow-connections sip to h323
allow-connections sip to sip
supplementary-service h450.12
redirect ip2ip
signaling forward unconditional
fax protocol t38 version 0 ls-redundancy 0 hs-redundancy 0 fallback none
