Dear development team, last week I completed the development of the prototype IMS - IMSinBOX. Development was done at the request of employer in order to create stand for testing and demonstration of its main products: OCS / PCRF. Since all basic IMSinBOX's nodes made using the code of the "Kamailio" I think it is necessary to provide the community of "Kamailio" developers all the fixes and additions, which made me in project, including: modules problems fix methods 1 ims_registrar_pcscf identification of the identification of the ims_usrloc_pcscf client based onto "Via" client based onto "host:port:proto" ims_qos "host:port:proto" mislead received usrloc & qos 2 siputils/ bug in the functions fix chargingvector settind, getting lib/ims/ ICID/IOI ims_getters 3 ims_charging bugs; fix; lack of IMS message implement ECUR using OMA charging CPM Charging Specification Best regards, Vadim Gribanovsky
