Capabilities of CISCO1921/K9

We currently have 3 of the CISCO1921/K9's maintaining a 1.5Mbps MPLS for our phone system. We are moving to a hosted VoIP, so we no longer need this. However, we are going to be opening a 100M VPN between the three sites. Will the CISCO1921/K9's be sufficient for this?

Well, I'm not positive about it.  In the ISR_G2_Perfomance.pdf that is linked above, on page 2 you see that the 1921 will do 2770 Mbps.  Please note that that is bits not bytes,  you convert that and its 346Mb.  However, please also note that this speed is without any ACL's or other factors.  ACLs add overhead which decreases throughput performance.  Also, if you move to page 3, you see the IPsec tunnel #'s.  

In my environment I have a DMVPN ipsec tunnel with a 100mb connection that serves an average of 10-20 branch offices.  I don't use a 1921 nor would I because I don't believe it has the CPU or backplane to handle it.  

But, there's a guy above that answered you with a CCIE who knows way more than me so he should know.  I'm conservative....I use a 2800 series.
