[Freeswitch-users] FW: [ERR] sofia_reg.c:1914 NO CONTACT!

[bulk orok]

Hi,

FreeSWITCH (Version 1.2.7 git 93e2a38) throws this error in the CLI when a REGISTER without CONTACT-header hits it. FS responds with 500 Internal Server Error
The requesting side is sending a second REGISTER with Contact then and it registeres.
Some "AVM FritzBox" hardware-boxes send such a REGISTER.

Here a (cleaned) SIP-Trace
