Jiri,
You are correct. Everything is working except for the error messages, which concern me
since I don't know why they're occuring or if they might cause instability.
I'll try the CVS version.
Thanks,
G.
So I don't understand from your description -- is there anything what is not working
except
some error messages?
What I really need now is a way to deal with the timer
issue. Jiri, I don't think I need multiple timers. I never want SER to timeout calls
placed to the PSTN. I just want one timer which I can apply to selective transactions.
Well, there is _always_ a timer for every transaction and the timer has always
the same value. The only thing which can be made distinctive is how this timer
is handled.
Right now, the timer causes all calls to fail. I
understand that I can change processing on failure, and I am doing this, but it would be
very nice if the timer could be used only for specific transactions. I think this would
involve setting it through a function call instead of a modparam call, but I don't
know since I haven't actually looked at any code.
The timer can't be removed -- it has a kind of "garbage collection"
responsibility
and a server without timers would run out of memory very quickly.
What you could do is forwarding to gateway statelessly -- then, there would be
indeed no timer involved. I don't think, that makes sense though for a couple
of other reasons like accounting and/or tcp2udp forwarding.
I've also tried to just relay PSTN calls again
(re-relay) through a failure route after the timer expires, but that doesn't seem to
be working too well. Is this possible?
What does it mean "it doesn't seem to be working too well"?
Anyway, I think it really would not work -- it would end up
canceling and re-ringing the PSTN destination, which is a kind
of undesirable behviour.
So in summary, I don't think there is an easy option for single-instance
ser and multiple-timer. A really straight-forward option is support in
SER.
Also, I think its not necessary to implement the
"single-ser" config that is capable of running voicemail if this dual
configuration works well. Of cource, the "single-ser" config would make it a
little simpler for users.
I would actually love to have it, it is just a problem of my time.
