[asterisk-users] SIP registration issues

[Terry Wilson]

I have not looked at the log files, but often times DSL routers may use PPPoE which has a little bit of overhead so you need to set the MTU below the default of 1500. Some info about the issue can be found here: http://www.ezlan.net/PPPOE.html and http://www.cisco.com/en/US/tech/tk175/tk15/technologies_tech_note09186a0080093bc7.shtml.

Another issue could be that the DSL router is doing a nat and you need to set nat=yes in sip.conf to get things to work.
