Re: [Linphone-users] Linphone does not send Accept header with SUBSCRIBE request

[Lorrin]

Hi Craig,

all mails sent out to the mailing list (address@hidden) are sent to all members. We are all geting those mails, as is supposed to be, so don't worry.
If the mail contents don't concern you, just ignore them, like those steps.

Best regards!

Hi Aymeric and John,
    Your system sends my emails to you, back to me.
    Also, I am not "John".   The email intended for "John" is coming to me (Craig).
    I did register to the mailing list a couple of days ago.   Perhaps look up my email address in your database.
    I received emails confirming registration.
    And I have no idea what you mean below "accept header" and
    the three steps 1, 2, and 3.  I am a Linphone SIP user not a developer.
Kind regards,

The bug tracker is not much used but you have an answer fast!

You email to address@hidden was also discarded, I guess you

didn't register to the mailing list before.

The Accept header should be added by linphone between

eXosip_subscribe_build_initial_request and eXosip_subscribe_send_initial_request:

1/step 1:

eXosip_subscribe_build_initial_request (&subscribe, url, identity, proxy_route, event, expires);

2/step2:

osip_message_set_header (subscribe, "Accept", "application/pidf+xml");

3/step3:

eXosip_subscribe_send_initial_request(subscribe);

Regards

Was able to fix this. For anyone else experiencing this: the issue is
within the exosip library. Fixed by adding this line to
eXosip_subscribe_build_initial_request in eXsubscription_api.c just
above the return statement:
osip_message_set_header (*sub, "Accept", "application/pidf+xml");

Submitted a bug report and patch file here, but it doesn't look like
the bug tracker is used much:
