SRST Problem

I am having a problem with SRST. Here is what is happening. The WAN fails, phones and gateway go into SRST correctly and inbound/outbound calls work correctly. When the WAN comes back everything goes back to normal and all is good. Now, this is working correctly because the "incoming called-number ." command is under the mgcpapp dial-peers. Here is the problem, if the gateway is reset the mgcpapp dial-peers are re-added but obviously this time without the "incoming called-number ." command. So inbound calls continue to follow the other pots dial-peers and not the mgcpapp dial-peers. I can disable ccm-config but I am hoping there is a better way. I have not had this issue in the past with SRST and I have now tried two different versions of IOS to be safe with the same result. Thoughts? Config is below:

Re: SRST Problem

Did you manage to find a solution for this problem? To me it appears as a bug. I am not able find many matching bug in the bug toolkit though!. What versions of IOS did you use btw?
