Since  you  are calling  using  PSTN, the call flow will be as mentioned below.

 

 

PhoneA>>EXPR-E>>EXPR-C>>GATEWYA>>PSTN>>GATEWAYB>>EXPR-C>>EXPR-E>>PhoneB

 

Read the below document.

Hello Shan28.

The default Media call flow without ICE implemented are as follows:

 

Client A <-> Exp-E_1 <-> Exp-C_1 <-> Exp-C_2 <-> Exp-E_2 <-> Client B

With ICE are just Client A <-> Client B

 

But Signaling following always this:

Client A <-> Exp-E_1 <-> Exp-C_1 <-> CUCM <-> Exp-C_2 <-> Exp-E_2 <-> Client B

Hi Nitin, 

 

Consider both are in different cluster(2 different customers) having reachability only through pstn number..
