Re: [Linphone-users] Linphone problems when putting o/b calls on hold.

Simon,

you should probably enable debugging on Linphone and check what it does when you hold the call. It should send out a reINVITE with a=sendonly in the SDP (and Linphone also adds a “Subject: Call on Hold” to the SIP headers).

So far everything seems to work as expected, except when I make an outbound (external) call from linphone, but then wish to put the called party on hold. I put the call on hold, the called party doesn’t get MOH, and I can’t get the call back. It ends up either dropping the call, or I have to hang up the linphone client.

Looking at the SIP trace from FreePBX, I can’t see where the Linphone client signals to put the call on hold, so I’m wondering if there is a bug or something?

Inbound calls to the linphone client can be put on hold, MOH is delivered, and I can get the call back.

Thanks

Simon
