SIP registration not possible
Issue generated from Tuleap's migration script. Originally submitted by: Robert Dyck (rjdyck)
This problem seems to be specific to Marshmallow or perhaps to Nexus-6p. I am unable to register any accounts. In the account status it says "ERROR_GENERIC". When attempting to register to my own local registrar, Wireshark does not show any SIP messaging. My Nexus-s can register although performance is poor due to this phones limited resources. Linphone seems to have the same problem and no messaging happens. The debug message from Linphone suggests a problem finding a working transport. There again my Nexus-s can register. Zoiper and Csipsimple on the 6p can register although Csipsimple has an unrelated problem with ipv6 DNS. The built-in android SIP is OK as well.
