Jeremy:
Yes. Using AVPs you can set the timers for inbound verses outbound calling
to different values (seconds). Something like:
modparam("tm", "fr_inv_timer_avp", "inv_timeout")
if (lookup("location") | lookup("aliases") | (src_ip==<your
pstn gwy ip
address>))
{
xlog("L_INFO", "\n[SER]: Call to local proxy user: Time: [%Tf] From:
<%fu> To: <%tu>
Method: <%rm> R-uri: <%ru> \n");
avp_write("15", "inv_timeout"); # (inbound calls to SER
subscriber
get about 4 rings)
};
or
if (uri=~"^sip:(9610|9215|9484|9267)[0-9]{7}@(<your proxy ip address>|<your
domain name>)")
{
xlog("L_INFO", "\n[SER]: Route block #3: outbound local call for
<%fu>\n");
avp_write("65", "inv_timeout"); # new
rewritehostport("<your pstn gateway ip and port>");
t_relay();
break;
};

I need to set inv_timer to at least 30 seconds to account for the
long failover times apparently used by cellular providers. Not hard
to understand; it takes a while to dig that cell phone out of the
pocket.
But this seems to cause inbound calls to take the same long time to
failover to voicemail (an Asterisk system running on a separate box.)
Do I understand the timers correctly? Is there a way to cause a
relatively short inbound failover and keep a longish outbound failure?
