Another question though: I tried to use SOATAG_LOCAL_SDP and SOATAG_REMOTE_SDP within my nua_i_state callback, but it gives me an assertion: WARNING: tag soa::remote_sdp directly used by tl_gets() Assertion failed: tt->tt_class == ref_tag_class Is it illegal to use these tags in that context? Their _REF version are working. How would I get the structure to the local SDP when I'm not in the nua_i_state callback? Would I use soa_get_local_sdp() using the session object directly from the nua handle? I mean like so: soa_get_local_sdp( nua_handle->nh_soa, &l_sdp, NULL, NULL ); I don't feel safe accessing members of the nua handle directly, that's why I'm asking.

You can do the actual sdp structure as well. For sure you will need the m lines in the sdp, if you do the structure, it can be sparse just like the string.

Alright, from the beginning: --- That's how I create the stack: sip_stack = nua_create( sip_root, sip_evt_dispatcher, reinterpret_cast< nua_magic_t* >( this ), TAG_IF( (! uas_id.empty()), SIPTAG_USER_AGENT_STR( uas_id.c_str() ) ), SIPTAG_ALLOW_STR( "INVITE,ACK,CANCEL,BYE,OPTIONS,PRACK,UPDATE,MESSAGE" ), NUTAG_URL( my_url.c_str() ), TAG_END() ); --- Placing a call involves these calls: nh = nua_handle( sip_stack, reinterpret_cast< nua_hmagic_t* >( this ), SIPTAG_TO( to ), TAG_IF( (NULL != from), SIPTAG_FROM( from ) ), TAG_IF( ((NULL == from) && (strlen(from_user ? from_user : "") > 0)), NUTAG_M_USERNAME( from_user ) ), TAG_IF( session_timer.useSessionTimer(), NUTAG_SESSION_REFRESHER( nua_local_refresher ) ), TAG_IF( session_timer.useSessionTimer(), NUTAG_MIN_SE( session_timer.minimumSessionExpires() ) ), TAG_IF( session_timer.useSessionTimer(), NUTAG_SESSION_TIMER( session_timer.sessionExpires() ) ), TAG_IF( session_timer.useSessionTimer(), NUTAG_REFRESH_WITHOUT_SDP( 1 ) ), TAG_END() ); nua_invite( nh, TAG_IF( (! additional_header_str.empty()), SIPTAG_HEADER_STR( additional_header_str.c_str() ) ), SOATAG_USER_SDP_STR( sdp_os.str().c_str() ), SOATAG_RTP_SELECT( SOA_RTP_SELECT_COMMON ), TAG_END() ); --- Accepting a call looks like this: nua_respond( reinterpret_cast< nua_handle_t* >( call_id() ), status_code, sip_status_phrase( status_code ), TAG_IF( strlen( sdp_str ), SOATAG_USER_SDP_STR( sdp_str ) ), TAG_IF( (! aux_codecs.empty()), SOATAG_AUDIO_AUX( aux_codecs.c_str() ) ), TAG_IF( strlen( reason_str ), SIPTAG_REASON_STR( reason_str ) ), TAG_IF( use_session_timer, NUTAG_SESSION_REFRESHER( nua_local_refresher ) ), TAG_IF( use_session_timer, NUTAG_MIN_SE( session_timer.minimumSessionExpires() ) ), TAG_IF( use_session_timer, NUTAG_SESSION_TIMER( session_timer.sessionExpires() ) ), TAG_IF( use_session_timer, NUTAG_REFRESH_WITHOUT_SDP( 1 ) ), TAG_END() ); --- My first (naive) attempt was trying to update the media mode like so: std::string sdp_media_mode_line( "a=" ); sdp_media_mode_line.append( media_mode.sdp_str() ); nua_invite( reinterpret_cast< nua_handle_t* >( call_id() ), SOATAG_USER_SDP_STR( sdp_media_mode_line.c_str() ), TAG_END() ); Of course this doesn't work since SOA doesn't know what media that attribute belongs to... I didn't try to include the media line (yet). What I'm basically trying to do is to change a certain attribute for all media of a certain type at once. Is there a more elegant way than USER_SDP_STR, or is it the recommended way to go?

[Sofia-sip-devel] How to change media mode in active call?
Hi! I'm somewhat at a loss here. I'm in a SIP call that I made or accepted with one of a=[inactive|recvonly|sendonly|sendrecv] in the SDP. There is only one media (audio). When I make or answer a call, I create the complete SDP and provide it to nua with SOATAG_USER_SDP_STR which is working just fine. Now I would like to be able to change the media mode mid-call using the same SDP as before with a new media mode setting, but how do I do that? I tried calling nua_update/nua_invite using SOATAG_ACTIVE_AUDIO but it was to no avail. Is SOATAG_ACTIVE_AUDIO the way to go or should I be doing something different? Any help is appreciated.

Re: [Sofia-sip-devel] How to change media mode in active call?
I know it works with USER_SDP_STR, what exactly is your call to update/invite? are you doing ACTIVE_AUDIO(1) ?
