Yes. This is called a shared line.

If CUCM: follow the normal process you take for associating a DN to a phone, just enter the same extension and partition on two devices.

If CME: When associating the ephone-dn to the ephone with the button command, just use the same tag on both ephones. You'll likely want to set the ephone-dn to dual or octoline.

PS- In the future please include the software name and version that is involved. Answers typically differ between platforms.

Hi Hassan,

If this is CUCM, when you populate the Shared DN (directory number)

on the DN config page make sure to fill in these two name related fields

Dear rob,

Thanks Again

Conferencing requires a Conference Bridge from the Media Resource Group List. Compare the Device Pools between the two phones to see if they match. If they need to be different because the phones are at diffeent locations, check that the MRGL assigned to both includes a CFB resource.

Also, check that the Maximum Calls on the DN configuration page (below the Display/ASCII Display fields) has a number high enough to start a conference call. The default value is four (4).

Dear Jonathan,

Thanks for your help, please note that

  • both lines are in different device pool, becase as you said they are in different sites
  • now i have 3 phones with same DN in two different location
  • Three phones in the the old site can make conference normal and when browsing the IP for any telepgone i see they are using G.711.
  • new three phones with same DN of old ones can not make conference and they appear in browsing as using G.722 althuogh they are in same device pool and the codec in region is configured to be G.711
  • we doesn`t configure MRGL, we have 2 CFB configured, phones assigned MRGL <>

any idea what is could be the problem

  • i want new three phones make conference
  • and i want telephone in different site make conference althuogh they are using different codecs (G.711 and G.729)
