Ask your provider for REFER support. Another workaround woulb be to have a B2BUA in your network. E.g instead of client ---- proxy -------------------------------gateway of provider use client ---- proxy ---- virtual-GW ---------------gateway of provider The B2BUA can be seen as a virtual-GW (border element, SBC, call it whatever you like). This is a setup I usually use: my proxy uses a "virtual gateway" which is completely under my control. This virtual GW writes CDRs, and handles multiple PSTN providers (also useful as for example you can change PSTN providers without changing the Kamailio configuration). Furthermore, such a "GW" is under your control and you can configure it to allow REFER. For the B2BUA you can user ASterisk, Freeswitch, ...... regards klaus
