Hi, One client have 2 SIP accounts: SIP1 and SIP2 with 2 different carriers: C1 and C2. He wants to forward all calls destined to SIP1 to SIP2. C2 is using FreeSWITCH. I don't want to register SIP1 as SIP trunk in C2 because if the number of SIP accounts is big, there will be a performance problem as each account will be registered as a SIP trunk. Can anyone help me by giving an idea and a config sample for FreeSWITCH. Thank you. -- Best Regards
