I have a setup as per the following,

Server A - FreeSWITCH (Location A)

Server B - Asterisk (Location A)

Server C - Asterisk (Location B)

Two Asterisk servers are trunked with FreeSWITCH.

In FreeSWITCH am establishing Conference via a Javascript. 

From Server B (Asterisk) if I initiate the call, it works absolutely fine by entering into the conference room. 

From Server C (Asterisk) if I initiate the call, am able to hear the first word (Please) from the message "Please enter your conference number" and then its blank. 

The network connection between Location A and Location B is MPLS. 

My dialplan is pasted here http://pastebin.freeswitch.org/22228

Comments would be much appreciated. 

Thanks.
