[SR-Users] Kamailio ICSCF strange forking

Hi all, I have deployed an IMS based on Kamailio 4.1.2 and I don't manage establishing a call. Users registration is OK but when I initiate the call from A(a)ims.net to B(a)ims.net, I notice a strange I-CSCF behavior The INVITE message goes OK from P-CSCF to S-CSCF then to I-CSCF. Till this point everything is fine... Then the I-CSCF performs its LIR diameter request and gets an Ok response from the HSS with a S-CSCF URI The I-CSCF forwards the INVITE at the received S-CSCF. BUT at the same time the I-CSCF generates a DNS request to resolve ims.net SIP SRV (it gets itself as answer...) and forwards a second INVITE (exact copy from the one sent to the S-CSCF) to itself So I have 2 copies of the same INVITE dialog travelling in the network and messing everything. Any idea of the cause of this behavior . Thanks for your support... Olivier
