The problem was not on the asterisk side.
Very VERY slow connetion to external mssql database (on LAN) for lookup of extensions. Any ideas?
the mssql-server is on a Dell PowerEdge 2950.
the CPU-load is almost zero so that cant be the problem.
When i make an outbound call, it lookups the number in the mssql-db. This takes around 25 seconds, that cant be right, right?
