Hi, I use Pjsip 2.0 and Asterik Server and I`m getting the following problem, when i use the function "pjsua_call_set_hold()": pj_assert(mi<s_->media_count) I think this happens, because the existing call has media activated Could someone help me? Thanks you in advance. Kind regards, Francisco -------------- next part -------------- An HTML attachment was scrubbed...
