voip link back up for leased line

[csco11063007]

Hi experts,

i have 3640 wan routers at each site with 2mb link.Also i have one 2mb backup link.

I have to pass 20 calls(g.729) and rest bandwidth for my data applications.

could you give configuration for serial interfaces of 3640 which connect these sites. How i can configure other link if the active link fails

thanks

you need to provide more information.

what type of 2mb link? frame relay? isdn? t1 cas?....etc.

is this a WAN link to another site, a link to an ISP or a link to the PSTN?

are you using CME, CCM or a PBX for call control?

where/how is your call processor connected to the IP network? at this site or another site?

Link- two 2mb leased lines to another site

Call controll -CCM 4.1.2 and PBX

Call manager cluster on both sides (both side having one publisher and one subscriber )

Both side having around 1000 ip phones
