Mark,
did you look at the OpenSER logs and/or did you use tcpdump/grep to find
out what is going on? Did OpenSER receive the 100 Trying reply from the
phone, if yes, when? Did OpenSER generate 408 Request Timeout reply to
the caller, if yes, when?
If OpenSER really receives 100 Trying reply from the called phone, then
it sets up the fr_inv_timeout timer. After fr_inv_timeout timer expires
OpenSER generates 408 Request Timeout reply to the caller, but it does
not send CANCEL to the called phone, unless the noisy_ctimer parameter
is set, so the phone continues ringing. May be your phone itself has
some setting to stop ringing after 60 seconds if the user does not pick
up the phone.
Regards,
Anatoly.
Actually the original question was simply trying
to control the length of time that caller had to
wait before being transferred to voicemail. I have now tried setting:
modparam("tm", "fr_timer", 10)
but the phone still rings for a full 60 seconds.
The docs for 1.2 state that the default is 30 seconds. Any more ideas.

Hi,
I think the original question was not about generating CANCEL (to the
callee) or not. It was about the length of the timer. Please read the
description of the ft_timer timeout. After INVITE is sent to the callee,
only ft_timer is set. When a provisional response is received (1xx) then
fr_timer is removed and fr_inv_timer is set. The default value for the
fr_timer is 60 seconds. This is why you are getting the timeout of 60
seconds no matter what value for the fr_inv_timeout you set.
By the way, the "408 Request Timeout" reply to the caller is always
generated when one of the timers expires, it does not matter if
noisy_ctimer parameter is set or not.
Regards,
Anatoly.

Hi -
I am using 1.2.1-notls. When using t_relay() to INVITE a call, I
assume that the timeout before returning a 408 would be governed by
fr_inv_timer and fr_inv_timer_avp. Although the 1.2 documentation
states that the default for fr_inv_timer is 120 seconds I seem to get
a timeout at 60 seconds and neither fr_inv_timer or fr_inv_timer_avp
seems to have any effect. Have a made an error in interpreting the
docs? How should I be varying this timeout?
That timeout just mean how long OpenSer stores transacction information
in
order to match repies and retransmissions, no more.
If you want OpenSer to generate a CANCEL (to the callee) and a 408 (to the
caller) when that timer expires you must enable this parameter:
modparam("tm", "noisy_ctimer", 1)
Regards.
