[Asterisk-Users] RE: Clustering

[asterisk at gafana.com]

Quick question, you said a lot of your clients are using IAX....what kind of clients are these?  Are they running some kind of softphone or are there hardphones that use IAX?
   
  My main concern with SER is that if I have customers where I need to put * boxes on site, it will cause issues to try to do an IAX trunk between my main facility and the on-site * box.  
   
  Is it possible to do a SIP trunk??  I totally imagine yes, but I tried doing this (spent 2 hours) and had one problem after the other (mainly authentication issues).  If I can trunk my main servers to on-site customer servers via SIP, I will have no problem running SER!
