i would like to carry some oversea pstn-destinations via sip to providers like stanaphone, however, in case of a network-failure or if the provider is not available, i want to fallback to the zap-channels so the call is carried out to the pstn directly. the usual approach would be to check the dialstatus(e.g.NOANSWER). however, asterisk tries >60seconds to reach that peer(even when the ip i'm sending the call too is a dead end(no host)). i could limit a call by setting a timeout but this limit would also apply if a final destination doesn't pick up within the timeout. so basically, when i send a call via a sip-channel, i would like to know the network-status of the foreign host immediately(at least within 5 seconds) so i can reroute the call without having to wait for a host that is probably dead...
this seems to be possible with iax and CHANUNAVAIL, (http://bugs.digium.com/bug_view_advanced_page.php?bug_id=3360&history=1), though i haven't tried it. also i _need_ to use sip, iax (currently) is not an option. is there any mechanism in asterisk that allows to get the vital sip-status of a foreign host?! thanks for your input!!! ;-) regards christian _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
