[Sofia-sip-devel] REFER with REPLACES
Hi there, I'm trying to use the Sofia-SIP library to perform an unattended call transfer. E.g. If I'm A and in a call with B and C, I thought I could transfer so that B and C are talking with something like: sip_replaces_t *replaces = nua_handle_make_replace(nua_ handle_B, NULL, 0); nua_refer(nua_handle_B, SIPTAG_REFER_TO_STR(addr_C), SIPTAG_REPLACES(replaces), TAG_END()); However, when I do this I immediately get a nua_r_refer/400/Replaces header not allowed, and no further action is taken. I'd appreciate it if someone could point out my error, or what I can do to get around this.

Do you have replaces in your supported string? try SIPTAG_SUPPORTED_STR passing a string that includes replaces in nua_set_params or nua_create. I assume the othe sides your talking to support replaces too?

Ah, indeed the problem is that the other side does not support this. I'd been assuming it was just a standard feature of all SIP clients - thanks very much for pointing this out!
