I don't understand exactly the scenario that does not work. So you have 
a BLA group and 2 simultanous calls coming to it? And when then calls 
are answered everybody looses state except for the parties involved in 
the call? Is this it?

[[scb]] Anca, There are several failures. I tried to describe a more common problem to see if anyone in the community is also experiencing such an issue.

[[scb]] The symptom is partly like the "stale dialog when call on hold" bug however it is not clear if we have the exact same issue.

[[scb]] We have a BLA group consisting of eight phones. Two people call the BLA number from the PSTN. Each call is answered, one call per set. The first call is put on hold. When the second phone arrives it is answered and also put on hold. If at that time the second phone sends a notify the state in the notify message equals full essentially erasing the state of the first call from the presence server. As a result the phones believe they still have the first call on-hold but it cannot be retrieved.
