[Freeswitch-users] Call hold issue

Hello, I have a weird behaviour with a call hold scenario. When the customer on leg A is placing the call on-hold (by sending a RE INVITE with sendonly attribute in the SDP), Freeswitch is switching to hold: "Callstate Change ACTIVE -> HELD". But only on the leg A. The holding is not forwarded to the leg B. So, it causes the called party not to hear the Music On Hold generated by the calling party. Any idea of what could result in this behaviour? Regards, Igor.
