I believe the related bug id is: Bug ID CSCvh30732 Kind Regards James Dust ICT Network Infrastructure & Communications Engineer [cid:image005.png@01D17638.0229E040] 55 Bishopsgate, London EC2N 3AS Telephone: 020 7149 6314 / 07989 491136 Website<http://www.charles-stanley.co.uk/> | LinkedIn<https://www.linkedin.com/company/charles-stanley> | Twitter<https://twitter.com/_CharlesStanley> From: cisco-voip [mailto:cisco-voip-boun...@puck.nether.net] On Behalf Of Reto Gassmann Sent: 20 March 2019 09:54 To: cisco-voip@puck.nether.net Subject: [cisco-voip] 8851: always use first line for outbound calls with multiline Hello Group we have some IP Phones (8851) with two lines. For outgoing calls the first line is always used. However, if the user receives a call on the second line (This is his secret privat line), the next outgoing call is initiated from the second line and sends the wrong (privat) number. Is it possible to configure the phone that allways and automatically the first line is used for an outgoing call. We have CUCM 10.5 and 8851 IP Phones.
