[Freeswitch-users] Newbie question

[Michael Scheidell]

looked at FAQ's first, just want to clarify.
Some background, looking at replacing a running sipx install due to 
limitations on ITSP's
(conflicting ITSP and sipx limitations)
Biggest limitation I see is that sipx without an external SBC forces the 
ITSP to send calls to port 5080.
(Big Sip trunk providers like ATT, Level3 and Verizon don't want to do 
that.  I actually understand why)

in the firewall ports section it notes port 5060 for 'default' internal, 
5070 for default nat and 5080 for default external.

I suppose the biggest question is can I set up freeswitch to listen for 
SIP inbound trunk calls on port 5060 without loosing functionality
(with sipx, if I do this, I can't forward calls:
<http://list.sipfoundry.org/archive/sipx-users/msg23554.html>

I don't want to interfere with normal sip: url inbound calls, so I would 
expect (in an 'askerisk like' setup) to be able to receive sip calls to 
internal extensions as well as SIP trunk calls to port 5060.  (and be 
able to put both on hold, take them off hold, play moh to callers, 
transfer, blind and attended, and join a 3 way conference call)

Next, looking for someone who has moved from sipx 4.2.0 to 
freeswitch/fusionpbx to quote me on a conversion (assuming I can use the 
above)

POC would be to use someone like voip.ms and static registration (which 
uses port 5060).  and have full regression testing.  inbound calls, 
outbound calls, calls transfterd, (correct caller id shows up!)

Currently, this only works on voip.ms user/password authentication since 
the invite/auth exchange will register port 5080.
voip.ms has no way to specify the calling port, and even if they did, 
this is just the POC.  Level3, Att and Verizon will ONLY send to port 5060.

(ps, ISN dialing.  seems to be tied in to e.164 dialing, but I was not 
able to actually tell if that is the case.
on sipx, I added a two digit 'trunk' code '**' to make outbound ISN calls)
