Shared Line Calls get dropped

Hi there,

I have a strange problem, running a support line on several phones, all

using EM. The first line is the DDI and the second line is a shared line

for the department. If now someone is having a call on the shared line,

and a second call is coming in, the shared line rings on all phoness,

someone picks up and we have two calls properly set up.

If now the fisrt person ends his call and hangs up the other call on the

shared line is most of the time also dropped. Has anyone had this

problem before? I can't explain, why this should happen, Is there a

thing like a conference going on, for the CCM?

I can't see anything in the trace, seems for the CCM a normal operation,

I will raise the debug level and see, if I see any hint.

Many thanks,

Hi Christian,

I remember reading about a Bug with Shared Lines that sounded exactly like this but I'll be darned if I can find it now. Can you please let us know your CCM and Phone Firmware versions and I'll have another look.

thanks for the reply. We are running CCM 4.2(3)sr1 as I can remember. I do not know the actual firmware, but it the version which is on 4.2(3)sr1. It happens on the 7961 and IP Communicators. I have also to admit, that the shared line is spread over phones, which are not in the same network, so that I thought, it could be a problem with the network. I have found the following in the CCM trace:

05/10/2007 15:15:02.268 CCM|StationD: (0000034) SEP000F20FD9003 , INFO star_MediaExchangeAgenaCloseLogicalChannel can't find call=50331966 partyId= 3000aa1

Do you need more out of the debug?
