In the standard configuration this means that the last retransmission before t2 kicks in, has an error up to 4 times bigger then the initial one (the rounding error is max. 1 tick/62.5ms for the initial interval => up to 250 ms for the last retransmission before t2). By keeping the retransmission intervals in ms instead of ticks, this problem is avoided, and the timing error is always < 1 tick (62.5 ms) + system timer error (< 10 ms usually). --- modules/tm/config.c | 8 ++-- modules/tm/config.h | 4 +- modules/tm/h_table.h | 9 ++--- modules/tm/t_funcs.h | 10 +++-- modules/tm/t_lookup.c | 55 +++++++++++++++++--------------- modules/tm/timer.c | 85 ++++++++++++++++++++++++++++--------------------- modules/tm/timer.h | 60 ++++++++++++++++++---------------- modules/tm/tm.c | 4 +- modules/tm/uac.c | 4 +- 9 files changed, 130 insertions(+), 109 deletions(-) Diff: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commitdiff;h=a92…
