Description: Hi,

I can call from analogue phone to SIP-phone, I can receive inbound calls on analogue phone, but can not do outbound analog calls.

That outgoing calls do not work, only happens when dahdi+asterisk are loaded during boot-up on my OpenSuSE 11.1 system. When asterisk+dahdi are started by hand, no problem !

So, first of all I disabled "Parallel Execution" of start-up scripts for the services during boot, to start all services in serial. SuSE by default starts services, which do not depend upon each others, in parallel within the same run-level.
Second, I made shure, that dahdi is started "far erlier" than asterisk.
Third, I used the "Last Weapon of a desperate Programmer" (who suspects a timing problem; I am a programming-dinosaur myself, never needed to use it permanently): I introduced some time-delay in /etc/init.d/asterisk. Below you see this in more detail.
And now it works.

But that means, there is still a race-condition/timing issue/load-problem etc. during start-up of dahdi and asterisk after boot. Which I also had using asterisk/zaptel, but did not report.

asterisk -vvvvvvvvvr, when trying to do analogue call from phone to PSTN:
