Jabber drops conference calls

Level 1
Level 1

Hey guys,

when I try to start a conference call with my jabber client in deskphone mode (!), the third called phone rings for half a second and then the call is dropped. The call between the 2 "starting callers" can be continued.

Starting conference calls with our deskphones is possible without any problems.


We're running a CUCM, CUC and a CIMP in  version 10.5. Jabber is version 9.7.2..

Hope you can help me out with this.


Thanks in advance!

Hi, Do you have media resource list with conference resource applied to your jabber? Do you have same issue for external and internal calls? Regards.

Hey Emmanuel,


yeah thanks, i already had configured MRL/MRG with correct associations. 

Well, indeed i solved the problem and its kind of embarrassing:

The thrid participant was not using his jabber as a cti devices (1 and 2 were), he was using it as a softphone. 

Of course he had no CSF-Profile for it. 

After also the third participant configured his jabber in deskphone mode it worked out fine.


Thanks for your effort!
