Hi guys, I was reviewing sip srst configuration from a different sources and didn't see any ephone-dn configuration , how router will know which dn must be registered ?
example of the config:
voice service voip
ip address trusted list
ipv4 10.210.255.11
ipv4 10.210.255.12
ipv4 10.210.255.13
ipv4 10.210.255.14
ipv4 10.210.255.15
ipv4 10.210.254.2
ipv4 10.210.254.6
ipv4 191.0.0.0 255.255.255.0

The phone itself will create the appropriate virtual dial peer when it registers via SRST. You maximums are defined here:
voice register global
mode srst
max-dn 100
max-pool 15
Plus, it will only allow phones to register that are from the subnet defined in the pool.
The user doesn't enter an extension, the IP phone registers to the SRST router with the same DNs it was assigned by CUCM.

at this case user can enter any extension on his phone and be registered on the router, correct ?
I see "dialplan-pattern 1 732549.... extension-length 4" <- this I guess controls extension length on that phone.

right, they have assigned DNs already, I had confused with thing we use EM in the office, when users enter their EM extension to login.
Thank you
