Pas abouti

Impossible de parler dans le téléphone vers le Visio. Yak ne me demande jamais l’accès au micro et dans les parametrage le micro n’apparaît pas.
Pareil quand je suis en call pas de voyant orange en haut à droite…

Response from developer

Bonjour,Par "Visio", vous faites référence aux appels vidéo (SIP Video), c'est bien ça ?Yak Phone prend entièrement en charge les appels vidéo, mais cela dépend de la configuration de votre serveur PBX (Asterisk, 3CX, FreePBX, etc.). Voici les points à vérifier :Les Codecs : Assurez-vous que les codecs vidéo (comme le H.264) sont bien activés sur votre PBX et sur votre ligne SIP.Le Support Vidéo : Vérifiez que l'option "Soutien Vidéo" (Video Support) est bien cochée dans les paramètres de votre extension sur votre serveur.Le NAT / Pare-feu : Les flux vidéo nécessitent parfois une configuration STUN/TURN correcte pour traverser les pare-feux.Pourriez-vous me dire quel serveur PBX vous utilisez ? Cela m'aiderait à vous guider plus précisément.Merci pour votre retour ! contact@haoqi.uk

App full of bugs

Won’t stay connected to sbc, and can only reconnect on hard close and open.

Terminates call on connection via sbc, firewall, nat reflection.

Linphone works just fine.

Response from developer

Hi,Thank you so much for this highly precise and technical feedback. Edge cases involving SBCs, aggressive firewalls, and NAT reflection are exactly what help us refine Yak Phone and bridge the gap with mature solutions like Linphone.The behavior you described strongly suggests a SIP Keep-Alive/Re-registration issue (hence the need for a hard close to force a fresh binding), combined with a SDP/RTP media negotiation failure when traversing the NAT reflection (which causes the immediate call termination upon connect).We are committed to squashing this bug as soon as possible. Could you please help us isolate the root cause by emailing us at contact@haoqi.uk with:The application logs or, if you have access to your SBC port mirroring, a PCAP trace (Wireshark) of the registration/call attempt.The transport protocol you are using (UDP, TCP, or TLS).The brand/software of your SBC (e.g., Kamailio, OpenSIPS, Anynode, etc.).If you are open to it, we would love to invite you to our TestFlight beta program so you can test the hotfix as soon as it's ready.Thanks again for your expertise and valuable help!
