Hello Everyone,

It seems that when doing conference calling on VFX, the call breaks up, we have taken the phone to a different (faster) connection and this fix the problem.

It seems that the joining of the two calls to a conference call is done on the local device (in this case a SPA922) so on slower connections (Stream and I assume River) the calls breaks up and appears garbled.

Has anyone else found conference calling to be problematic on Stream connections?

Does anyone know for sure if the merging of the conference call is done on the local device?

The conferencing should be stitched together at the network, not the ATA. It may be a codec issue; as most devices are only licenced for 1 simultaneous G729 call, it may be switching to G711 for the conference call.

Make a 1-1 call and monitor the ATA status page and confirm it is using G729.
Then make a conference call and see it then uses G711.

G711 uses more bandwidth, so not so good on a 128up connection.

I'm not sure if my theory here is correct, so let me know what you find out.

Chorus has spent $1.4 billion on making their xDSL broadband network faster. If your still stuck on ADSL or VDSL, why not spend from $150 on a master filter install to make sure you are getting the most out of your connection?

All Linksys devices switch to g711 for three way calling - this would require you to have around 160kbit as a minimum available bandwidth.  Hence the full speed upload plan works fine as typically most of them can do 512kbit or better.
