[Asterisk-Users] Unable to create channel of type 'SIP'

[Ronald Wiplinger]

I (601) call one of my users (8862), after one minute I try to call him 
again  and get "Unable to create channel of type 'SIP' "

sip show peers does not list him.

I cannot figure out why this happens and more important how I can fix it.
