[Asterisk-Users] Any work around for ISPs that block port 5060 and69

[Kanuri, Seshu (Company IT)]

Yes, there is a solution. 

Use IAX2 both on Server and Clients and bypass all that Port mapping
crap.

There are a few brands of VOIP Phones available in the market that can
do IAX2.

Subject: [Asterisk-Users] Any work around for ISPs that block port 5060
and69

I have a several friends registered on my asterisk box that are
experience problems with their ISP blocking SIP default ports 5060 and
tftp port 69.  Is there any way around this problem or are they forever
doomed to VOIP since their ISP is pretty much the only ISP company on
that island.  So far I was able to have them change their default SIP
port to 6070 and any packets coming in on that port on my asterisk box I
would redirect to port 5060.  That seem to be working fine, expect that
they can make calls but cannot receive calls.  I think part of the
problem might be that when asterisk tries to initiate a call to their
sip phone it tries on port 5060 instead of 6070 even though I have
specified in the sip.conf that their port is 6070.  Has anyone else
encountered this problem and was able to resolve it?  My other option is
to change my asterisk box to work completely on a different port, but I
am reluctant to do so since the majority of registered users for now do
not have an issue with port 5060 being blocked by their ISP.

Thanks for your help.

Joel
