Hi,

As mentioned by Nadeem, mixing shared-lines between SCCP and SIP was introduced with CME 9.0 which is starting from 15.2(4)M

Is there any other way to share both telephone without upgrading the IOS version?

Assign two different DNs to SIP and SCCP phones. Then try to configure SNR to dial the other phone when a call rings the first one.

Can you please elaborate your answer Sir Mohammed Al Baqari.? Step by Step please with configuration. Thank you
