10.5(1.98000.186) 9.1(2.13050.1)

Description (partial)

Symptom:
We Cannot configure a pattern using  'IP Address Routing' to match all ip address with a single SIP route pattern (Like we use '*' for domain routing).

Conditions:
Domain Routing:

In SIP Route Pattern with Domain Routing, we can use '*' to match all URI dialing using domain to route the calls via SIP trunk. However, it is noted that the '*' can be enabled on UCCM 9.x onwards. On CUCM 8.6 and lower, we need at least specify the domain (example: *.com).

Domain name examples: cisco.com, my-pc.cisco.com, *.com, rtp-ccm[1-5].cisco.com
Valid characters for domain names in SIP Route Pattern: [, -, ., 0-9, A-Z, a-z, *, and ].


IP Address Routing:

If we use IP Address routing we need to specify the ip address. We can specify this using the subnet.
Example: if we are dialing  'joe@10.10.10.1', then the SIP route pattern can be,
10.10.10.1 or 10.10.10.1/16(IP subnet)
IPv4 address examples: 172.18.201.119 or 172.18.201.119/32 (explicit IP host address); 172.18.0.0/16 (IP subnet); 172.18.201.18/21 (IP subnet).
Valid characters for IP addresses in SIP Route Pattern:   0-9, ., and /


But we Cannot configure a pattern using  'IP Address Routing' to match all ip address with a single SIP route pattern (Like we use '*' for domain routing).
