Hi Anthony,

as far as I see the mentioned patch doesn't address my problem. I looked
into "sofia-reg.c" and found that FS's already append "expires" to
"contact-header" when a SIP client is registering (as mentioned below).

I applied the following patch which solves the issue with Aastra DECT
SIP OMM-RFPs to sofia_reg.c:

 #endif
                } else {
+            sip_contact_add_param(nua_handle_home(nh),
sip->sip_contact, "expires=0");
                        if (switch_event_create_subclass(&s_event,
SWITCH_EVENT_CUSTOM, MY_EVENT_UNREGISTER) == SWITCH_STATUS_SUCCESS) {
                                switch_event_add_header_string(s_event,
SWITCH_STACK_BOTTOM, "profile-name", profile->name);
                                switch_event_add_header_string(s_event,
SWITCH_STACK_BOTTOM, "from-user", to_user);


The only thing what happens is to add "expires=0" parameter to
contac-header when replying "200 OK" to a client's (UN-)REGISTER message.


Shall I open an issue in Jira?

regards
helmut
