[cisco-voip] Location Question

[Syed Khalid Ali]

If you are using IPSec VPN around 50-70 bytes are further added.If you
use the TAC VoIP bandwidth calculator
(http://tools.cisco.com/Support/VBC/jsp/Codec_Calc1.jsp), around
28kbps is allocated. And don't forget additional 24bytes for GRE
header also.

I already have CCM CAC in placed but I am thinking how it will react
when DMVPN is used. RSVP is supported with CallManager 5 and onwards.

I am curious why Cisco added this static 24kbps for G.729 calls.

Any comments from experts on this groups.
