We have users that change their location between two offices. The 1st office does not have extension mobility, they just have their personal IP phones (desk phones) with their extensions. The 2nd office has extension mobility service enabled; when the user is in the second office he will use extension mobility service.
This is what we use in the second office: any phone is hotline device (SIP dial rule for hotline). When the user lifts up the headphone, he hears a prompt with the instructions to log-in to Extension Mobility with his device profile. The problem with this configuration is: because of the "SIP dial Rule" is a device configuration parameter, when the user logs-in, he isn't able to user his extension. Is there any way to disable this parameter when using extension mobility (put it in <none>)? Or any other solution that accomplish this one?
Why do you need sip dial rules? What model of phones are these? Why do you need to play prompt for users to login?
We are using SIP phones model 7841 and 9951. SIP dial rules because of the hotline configuration. The prompt tells the user the instructions to log-in via Extension Mobility.
Are you running CME or CUCM?
Too hard, man. Just put a default device profile on the phones at office 1, so this way the phone at that branch will always have that person's profile logged in, and configure a service on the phones at branch 2, so people from office 1 can log in on phones at office 2. This saves you from doubling up extensions to have to be configured on both a phone and a user device profile.
We don't have the same number of phones in the branch office compared to the core. Users share phones with other users in the 2nd office, so phones at the branch office can't have always the person's profile logged in. What is essential to the client is that the user hears the instructions when he lifts up the headphone in the branch office.
Thanks for your answer.
Having a similar problem...
8851 SIP Phones. We basically just need them configured as "Blank EM" phones with no extension and the "Extension Mobility" service on Button #2.
The main issue, however, is that these phones won't Register unless a DN is configured on Button #1. So that led me down the PLAR route.. Configured extension 1000 with a Line Text Label of "Phone Logged Out" and set-up PLAR to basically ring down to extension 1000 and forward to Unity with a greeting stating that the phone is logged out. Also allows for a Press 1 for Help Desk in case people need their PIN reset.
This config works great on our 7965's (SCCP), and it almost works just as well on the 8851's with the SIP Dial Rule configured for Button #1. Except, once a user logs in with Extension Mobility, the SIP Dial Rule still commandeers Button #1.
Any ideas how I can get around this?
