Hi, there! I would like to find out is there anyway that the SER server can communicate to other SIP servers? For instance, I have an account at SER and another account at SIPserver B. I would like to call from SER to SIPserver B, and vice versa. Is it workable? Or any additional devices needed in between these 2 SIP servers? If yes, could anyone give me some clues or guide to do so. Thank you. Best Regards, Roa yu
