ver 3, vol2 Lab 2 Section 8.1 SRST
Thanks for all your replies so far.
This is a suggestion on the solution guide. There are some errors.
Solution guide assumes the R2 (BR1) is in MGCP mode, but actually its in H323 mode. so, you dont need configuration below;
=> call application alternate default & ccm-manager fallback-mgcp
Also the Translation profile is not needed. Instead dial-plan pattern under the ccm-manager-fallback yeilds the maintaining the dial-plan during fallback to SRST.
