Re: [SR-Users] Time elapsed since previous message.

Actually I already implemented that timeout, I haven’t asked about that, because I didn’t have any problems with that one. I am being asked for that “if a 180 comes within 0.8 seconds, cancel the call and send a 480 to the origination. The cancel I got it working thanks to your help. Sending back a 480 to the origination is what’s proving more difficult, I just can’t figure that one out.

That is, if, upon receipt of a non-100 1xx message, a final dispositive reply does not follow within X seconds, route-advance to the next provider? This can be accomplished with the t_set_fr/t_reset_fr() technique previously discussed. It sounds like you might be making this unnecessarily complicated. :-) Don’t worry about how quickly they send you the progress/alerting messages; instead, worry about how slowly they send you anything else afterward. The only wrinkle I can see that in that is the caller experience... — Sent from mobile, with due apologies for brevity and errors. > On Feb 10, 2021, at 2:13 PM, David Villasmil > &lt;david.villasmil.work(a)gmail.com > <mailto:david.villasmil.work@gmail.com>> wrote: > >  > Some providers have other providers which many times just answer > the call and try to keep it there.
