[Freeswitch-users] sometimes some internal calls abandoned!

[Vallimamod Abdullah]

I have seen this state happen when the incoming UA does not respond to the authentication challenge. These are usually bots trying to find open installations and who don't bother to answer when they receive a 407 (i.e. they "abandon" the sip transaction).


Best Regards,
