[cisco-voip] CME -to - CME call fail

[Adewale2]

Hello All,
Could anyone advice on what could be wrong on CME - to-CME calls,
 I have site-A with CME-A and site-B with CME-B, That have been working for 3 years now.
A week ago I made changes to IP address subnet and interface of the CME-B Site B.
Since then ,CME-B can call extension in site A, while CME-A cannot call extension in Site B.
I ping ping both CME From Site-A to Site -B and from site-B to Site-A.
Any help please 


CME-B , can call Extension in Site A, but CME - A cannot call Extension in Site B
