[cisco-voip] SRST automatically set to G.729 CODEC instead of G.711

[Jorge L. Rodriguez Aguila]

This is a great option unless They Change Moh frequently. Then it becomes a management nightmare. I had a customer who complained about the G.729 MOH quality and we placed this option. After having to change the MOH files on 30 some servers twice in a month he gave up on it. I don't blame him, it is tedious work :-D

I have been doing this on every SRST router I deploy, it works very
well and the sound quality is very good...
