Hello, I wish to integrate Open IMS Core and FreeSWITCH such that an IMS user can call a FreeSWITCH user and vice versa. I have succeed in establishing a call from an IMS user to a FreeSWITCH user. IMS provides a feature of forwarding a SIP INVITE request based on a filter. But I am struggling to establish a call from a FreeSWITCH user towards IMS. Does FreeSWITCH have a feature where it can forward an INVITE request based on a filter? I will greatly appreciate any help that can lead me closer to the solution. thanks and regards Jaytirth *Disclaimer* ------------------------------------------------------------ Notice: This e-mail and / or attachments (communication) may contain information that is confidential and proprietary to The Tata Power Company Limited, Strategic Engineering Division (Tata Power SED).
