[Freeswitch-dev] FS-2875 SIP REGISTER Fetch (without Contact header)

[Leon de Rooij]

Hi all,

Can someone please take a look at http://jira.freeswitch.org/browse/FS-2875 ?

Especially the last few comments and last patch which is here: http://jira.freeswitch.org/secure/attachment/14120/sofia_reg_enable_register_query_with_optional_multiple_contacts.patch_4.txt

With this it is possible to fetch bindings by sending a sip register without contact headers. A regular register also responds with all bindings that are in the db now (see traces below).

Thanks,

Leon
