I use the MCU software In my HDX 9006 unit to make multipoint calls. Depending on which site I call first, when I share content only the first endpoint I dialed first will see the content, the other sites cannot.
Something must have changed because a year before I did not have this problem. Any ideas?
welcome to the Polycom Community.
It is always useful to include the currently used Software version as issues experienced or a question asked may already be addressed in a newer release.
This also allows yourself and others to check against current software release notes, Administrator Guides or FAQ post’s.
The above is also stated in the "Read First" and is the basic minimal requirement for a post.

Have you tried getting a packet capture of a session where the issue presents itself? Using Wireshark to view the call setup and media negotiations might give some clues as to whether subsequent connections are presented with the content channel.
I am wondering if the call transport type has anything to do with it.?
Look at the attachment and tell me what you think?
One is connecting as H.323 and the other as sip.
We enabled sip last summer in order to halt some of the phantom calls we were receiving during connections.
Probably the units not receiving the content aren't able to support the content channel method being used by the HDX. H.239 is used for H.323 content sharing and BFCP is used for SIP content sharing.
You might try all H.323 or all SIP in the multipoint call to see if that helps or at least identifies whether certain vendor, models or software versions are affected.
How are you sending content?
Well, should I change the way I place calls in the Preferred Dialing Method screen to have H.323 as 1 and sip as 2?
Certainly worth a try. If you have remote access to the far end units having the issue and are able to initiate a packet capture or have someone locally do it, the capture file might give some good clues. Most video units have the ablilty thru menus or telnet to do a tcpdump capture. Wireshark is used generally to interpret the captured file.
