Where is the T1 timer set in Ser? The RFC suggests a default of 500 ms for
round-trip time.
I have an ethereal trace showing Ser re-transmitting after less than 300 ms.
Anyway, because
of our environment I'd like to set T1 to be 1000 ms. I'm using 0.8.14.
thanks

It is retr_timer1p1 parameter of tm module.

Thanks for the pointer.
The docs I've seen say this is an integer in seconds, not milliseconds.
If this is correct, it doesn't seem to give much granularity in the
settings.
I'm also puzzled by the re-transmits I'm seeing in the trace.
If the default T1 timer in Ser is 1 second, then why do I see a re-invite
after 290 ms?
Could this be platform/libc specific behaviour?

For performance reasons timers in ser are not as precise as they should
be. So it can happen that the retransmission will be sent in less than
T1. This is a shortcoming in SER which will be fixed in one of future
releases.
