Valentina,

One follow-up question before generating the template.  Which voice codec is preferred?  G711alaw, as for UC320?  For UC500, we recommend configuring a single voice codec to avoid any renegotiation of codecs on different call legs that may be hairpinned.

Thank you.

Hi Laura,

We support all 3 codecs. We normally recommend G711alaw or G711ulaw as G729 its a compressed codec. When we did the testing the first codec that has been negotiated was G711alaw, so I will probbly ask you to stick with that.

Thanks.
