[SR-Users] Kamailio with Presence Module and Publishing by Asterisk

Hi,

I'm having a problem managing the presence between Kamailio and Asterisk. I have configured Kamailio as a presence server. Asterisk sends presence information via publishing sip request. My softphone which uses Kamailio as a presence server and as a proxy has 2 BLFs configured. On a first call, the presence status is displayed on the 2 keys. But for the 2nd call, only the extension receiving the call has its status changed on the BLF. Via sngrep, the Publishing requests arrive on Kamailio but the DB is not updated because the e-tag does not match. If I wait until the end of the expiry period (60s for the test), the DB is flushed and the 1st call works again.

Could you please help me? Thank you
