[asterisk-users] calls get stuck in asterisk

[Fons van der Beek]

When there are 3 or more incomming calls on my Linksys 962, it often 
happens that the calls are in the wait-state but not visible on the 
phone anymore

This happens when we want to transfer the call but the remote party 
doesn't answer.
When we want to take the call back it is gone, but the calling party 
still has music on hold
after a while this times out, and the call is ended by asterisk

Does this sound familair to anyone?
How can this be debugged? what information does anyone need to help me 
with this problem?

With kind regards
