asterisk users - Jul 2010 - Dial SIP channel with no registration, timeout before CONGESTION?

What determines how long SIP channel waits, when you dial a peer with no
registration, before returning ${DIALSTATUS} "CONGESTION"?

When I dial a peer with no registration, SIP channel currently waits
many seconds before returning ${DIALSTATUS} "CONGESTION" - how can I
shorten this timeout?

Look at qualify=yes for that peer.
Use ChanIsAvail() before you dial.
Use SIPPEER(peername|status) to check registration status.
Use DB_EXISTS(SIP/Registry/peername) to check registration status.
