[Serusers] SER listen on multiple ports

Hi all, I tried searching for a similar thread in the iptel archive, but can't find any related discussion, so please forgive me if some of you have discussed this issue previously for I did try searching for it!! :> I'm trying to have SER listen on other ports on top of its default (5060) without success. In my configuration, I tried.... listen=public-ip port=5080 port=5060 But users can only register on port 5060. Once I disable the line port=5060, users can now register on port 5080. I have even tried.... listen=public-ip:5060 listen=public-ip:5080 This resulted in SER failing to start. Therefore I had no choice but to move back to my 1st sample above in adding the port option. My question boils down to the following... Is SER capable of listening on multiple ports?? If so, how do I configure it?? Any help is appreciated! Best Regards, Samuel Yeung
