HOW TO CHECK THE ECHO CANCELLER IN ERICSSON MEDIA GATEWAY?

as a reply of your first question that how an outbound roamer will select correct VPLMN when there are many choices.
The answer is:
When subscriber is allowed for International Roaming, the GT (Global Title) of VPLMN MSC is added in subscriber's HLR of HPLMN in "IMSI->GT translation" section.
On very first LU (Location Update), the request is forwarded by VPLMN network to HPLMN'S HLR and only correct MSC is authenticated whose GT is present in HLR.
It will resolve your query hopefully!

How we can calculate Erlangs ?
Suppose we have 35 channels.
Blocking probability is 0.02
As per theory(Erlangs B Calculation)
Erlangs is 26.4.
How it is possible?
My doubt :
We have 35 resources or Channels.If all resources are using continuously for one hour, it is 35 Erlangs. If we are considering blocking of .02,the available Capacity should more than 35 Erlangs. Is it?
