    [ https://issues.asterisk.org/jira/browse/ASTERISK-20345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=203578#comment-203578 ] 

Massimo Nuvoli commented on ASTERISK-20345:
-------------------------------------------

I fall in the same problem of Pietro Quarantini, but i ask the provider to solve the problem.
This is the response:

"The problem is at Asterisk side, Asterisk is not RFC 3264 compliant:

5.1 Unicast Streams   If the offerer wishes to only send media on a stream
to its peer, it
   MUST mark the stream as sendonly with the "a=sendonly" attribute.

So to put a call on hold the call MUST be on, not in indication state.

and

8.4 Putting a Unicast Media Stream on Hold
   If a party in a call wants to put the other party "on hold", i.e.,
   request that it temporarily stops sending one or more unicast media
   streams, a party offers the other an updated SDP.
   If the stream to be placed on hold was previously a sendrecv media
   stream, it is placed on hold by marking it as sendonly.  If the
   stream to be placed on hold was previously a recvonly media stream,
   it is placed on hold by marking it inactive.
"

I was thinking to open a new issue, but i found this one.

I am facing a big problem, the provider (the same TWT) tell me that this is Asterisk problem, so they dont want (in short time) to solve the problem.

Thnks.
