I put those commands for IP phone:
Router(config)#voice register dn 45
Router(config-register-dn)#number 1000
Router(config-register-dn)#name Ahmad
Router(config-register-dn)#label Ahmad
Router(config-register-dn)#allow watch
Router(config-register-dn)#mwi
Router(config-register-dn)#exit
Router(config)#voice register pool 45
Router(config-register-pool)#busy-trigger-per-button 1
Router(config-register-pool)#id mac D4AD.71BE.6C09
Router(config-register-pool)#type 7821
Router(config-register-pool)#CODEC g711ulaw
Router(config-register-pool)#number 1 dn 45
Router(config-register-pool)#dtmf-relay rtp-nte
Router(config-register-pool)#presence call-list
Router(config-register-pool)#username Ahmad password 1000
Router(config-register-pool)#exit
Router(config)#voice register global
Router(config-register-global)#no create profile
Router(config-register-global)#create profile
Some numbers got this issue (call-forward b2bua all 302)
When I call example 45 it would go to other numbers like 302 or others.
Help me with this issue and solve it.
I shared the CLI screenshot
