Dear list,

Asterisk 11.25.0 user here. I’m trying to set up failing over to a second SIP peer if the first SIP peer doesn’t answer on our SIP INVITE
within 2 seconds.

In sip.conf I set timerb=2000 for this peer, but it doesn’t seem to have any effect. The timeout is 6.5 seconds instead, which is in line with this description from sip.conf:

“timerb: Call setup timer. If a provisional response is not received in this amount of time, the call will autocongest. Defaults to 64*timert1
(Which is 100 ms = rougly 6.5 seconds)”

Maybe I cannot set timerb on a peer-basis? Here’s my peer config:

[peer01]
host=1.2.3.4
type=peer context=nowhere disallow=all allow=alaw allow=ulaw canreinvite=no dtmfmode=rfc2833
timerb=2000

Thank you!
Markus

    You need to set timert1 in the peer config to *something*, otherwise it will ignore the timerb setting. Bug? It now looks like this and works fine:

    [peer01]
    host=1.2.3.4
    type=peer context=nowhere disallow=all allow=alaw allow=ulaw canreinvite=no dtmfmode=rfc2833
    timert1=500
    timerb=2000

    timert1=500 is the default anyway, according to sip.conf comments…

    Regards Markus
