Do you have SRST reference properly configured in CUCM and assigned to the phones'  device pool?

[Monzer Allam]

Dear Chris,

yes SRST reference assigend to phone device pool as per attached pic.

Thanks & Best Regards,

[Chris Deren]

Can you provide "debug ccsip all" when the phones are suppose to register. Did you define proper subnets of the phones under the voice register pool?

Chris

[Monzer Allam]

Dear Chris,

yes the subnet under the voice register poll is correct.

and i'm enabled the Debug CCSIP all

There is nothing showing in the debug implying the phones do not even attempt to register, yes please provide full config,

Chris

Try adding:

Voice service voip

 allow-connections sip to sip

 sip

   registrat server

[servicioshemac]

In my case that was the solution!!

Thanks!!
