Re: [Serusers] Advice needed

I would say SER is what you need, except that you struggle with the authentication. You have the following scenarios: 1. PSTN termination with IP-based access control (easiest) 2. PSTN termination with authentication of all INVITEs (yes, that's the UAC module. You should contact the maintainer, Ramona-Elena Modroiu about the status. I thought it was reported to work, but haven't tried myself) 3. PSTN termination with registration and authentication of REGISTER (but not INVITEs). Use sipsak to generate a REGISTER for your box. #2 requires that all INVITEs are sent twice and is not a very good option. I would seek out PSTN providers who will give you #1. g-) Michael Ulitskiy wrote: > Hello, > > I'd like ask for advice on what is in your opinion the best solution > in the following scenario. > I have a bunch of sip servers (asterisk boxes as my users need pbx > functionality) that can make sip call to each other and my PSTN > gateway.
