Hello everyone,
After our switch reload ,all of the ip phone can not dial, but the ip phone can get an ip address and tftp server.but they just can not register with the call manager...and I don't know why.
Here are my configuration:
!
ip dhcp pool Voice
network 172.28.0.0 255.255.0.0
default-router 172.28.15.254
option 150 ip 172.21.15.232 172.21.15.231
dns-server 10.64.0.101 10.176.0.101
!
SW254#sho ip dhcp binding
Bindings from all pools not associated with VRF:
IP address Client-ID/ Lease expiration Type
Hardware address/
User name
172.28.0.79 019c.57ad.b584.c4 Feb 12 2019 10:39 AM Automatic
172.28.0.80 01dc.cec1.d539.02 Feb 12 2019 10:44 AM Automatic
!
SW254#ping 172.21.15.231
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.21.15.231, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/11/17 ms
Thank you
