Duplicate Authorization Header during retry

[manzonif]

hi, I have problems in registering with my sip account. I guess it's due to the fact that, during the second retry, the authorization header is duplicated.

If I register the account through command line, the first attempt fails (Unauthorized)), but the second one has success:

REGISTER sip:sip.messagenet.it SIP/2.0 Via: SIP/2.0/UDP 192.168.1.235:5060;rport;branch=z9hG4bKPj1XrrxOPdbwSIIhBAVvlm.onYEoQnb.aN Max-Forwards: 70 From: sip:[email protected];tag=GaP2SnBihhckA4ohyDt2R3dek70XQYfp To: sip:[email protected] Call-ID: Ijefouh6.ptfvZnlNTC3iklkZbwDutVK CSeq: 26520 REGISTER User-Agent: PJSUA v2.6 Linux-4.9.35/armv7l/glibc-2.19 Contact: sip:[email protected]:5060;ob Expires: 300 Allow: PRACK, INVITE, ACK, BYE, CANCEL, UPDATE, INFO, SUBSCRIBE, NOTIFY, REFER, MESSAGE, OPTIONS Authorization: Digest username="5xxxxxxx", realm="sip.messagenet.it", nonce="WXIeUVlyHSVTcdQn/8lr0/Y/XEvQfkcvbmIEr4Zp0LzGPlrqh3AJKO0D38yA", uri="sip:sip.messagenet.it", response="5decad2161eec4c41905a3f331a778f6", cnonce="6LqUedwnQIrbPBuj1e7D2DzG4q5tO4lh", qop=auth, nc=00000001 Content-Length: 0

With sipster, Authorization header is duplicated and fail:

REGISTER sip:sip.messagenet.it SIP/2.0 Via: SIP/2.0/UDP 192.168.1.235:5060;rport;branch=z9hG4bKPjYYxEtG9OCohuX2BLIegJKjQ0jYQEvK1p Max-Forwards: 70 From: sip:[email protected];tag=lK0GQ-GFUROOYaDh90pOwFAjxyroxYL3 To: sip:[email protected] Call-ID: VbmrXY.RblC2vmrYrfQ-xbMEPGKiuIDc CSeq: 60848 REGISTER Authorization: digest username="5xxxxxxx", realm="*", nonce="", uri="sip:sip.messagenet.it", response="" Contact: sip:[email protected]:5060;ob Expires: 300 Allow: PRACK, INVITE, ACK, BYE, CANCEL, UPDATE, INFO, SUBSCRIBE, NOTIFY, REFER, MESSAGE, OPTIONS Authorization: Digest username="5xxxxxxx", realm="sip.messagenet.it", nonce="WXIx0llyMKZzuh9wmxmiqOlkAiqjPuN5bmIEr4Zp0LzGPlrqh3AJKPHXbNyB", uri="sip:sip.messagenet.it", response="9fad324af9e74f6c497853d8a3288eb8", cnonce="HbQAV56NE4cbzWN8daQfBnP0T37V95Q2", qop=auth, nc=00000001 Content-Length: 0

Any idea to fix the problem?

Thanks
