Hi,
after successfully generating my asterisk from source for my OpenSuSE 11.1, one problem showed up: I could call from analogue phone to SIP-phone, I could receive inbound calls on analogue phone, but could not do outbound analog calls, in case I started dahdi and asterisk automatically during boot. In case, I started dahdi and asterisk manually, it worked.
(I am using a TDM400-clone from OpenVox, A400P.)
I had a similar issue already in the past with older asterisk and zaptel, and I found out, that I could solve my problem with a “Dirty Trick”:
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 this trick permanently, though): I introduced some time-delay in /etc/init./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 asterisk/dahdi after boot, which more looks like a asterisk/dahdi issue and not like a SuSE problem.
But, can anybody with a real TDM400-card confirm this problem ?
Below some system info:
