I found another challenge on CUCM to dial URI with an IP-address as extension instead of domain name, e.g. room@172.30.12.13.
In SIP Route Pattern you can define a IP-address or IP-address range with use of mask e.g. 172.0.0.0/8.
But is there a way to define an IP-address range that covers all IP addresses? The CUCM 10.5 does not accept 0.0.0.0/0 or something similar.
And my deployment requires the ability to dial all IP-address ranges and forward the calls to the Expressway-C.
Any ideas or hints?
