[Freeswitch-users] Doubts over G729 passthru for 50ms ptimes

Hi All, I'm wondering if anyone out there is using G729 with 50ms ptime through Freeswitch, without proxy media? I am unable to get this to work, even in a very basic lab with just two clients and an up to date FS server on the same LAN. I can get G729 with 20ms working, but 50ms causes Freeswitch to hang the call. It might be that mod_g729 and mod_com_g729 simply don't support it, so if anyone in the know can tell me that would be great! Further info can be supplied, I believe I have tried pretty much all options.... Cheers, Ben
