Hello,
Is it possible to add ATCF/ATGW functionality in kamailio as P-cscf ? I have IMS network with kamailio as P-cscf, icscf, scscf and FHoss . ATCF/ATGW is necessary for handovers between 2G/3G and LTE networks.
Unfortunately you can't, because SRVCC is a capable between MME and MCS in your network. When the UE is moving on, the MME send "Take handover of the call" to MSC and move the surrect session control to MSC. You could read more about SRVCC in 3GPP TS 29.280. And FHOSS does not support interface between MME and HSS, With Best Regards.Mojtaba

Thank you for your response, If we need to handover of call in our network, What's the solution? is it possible to add external MSC Server to out network? or add a SBC with this ability ?

According to ETSI TS 129-280 V15, Your network must support Sv interface between MME to MSC. Your network infrastructure (EPC) should support this feature. So it is not intuitively related to PCSCF or SBC. Add external MSC server for what? Each 2g/3g network have it's MSC and it would be support Sv interface, too. With Best Regards.Mojtaba
