PAP2T second line will not connect

Question

I have two voip accounts with the same provider and I have two PAP2T adapters (one for each account).  I can get either one to work by themselves.  I need to get both lines working on the same router.  If I hook both PAP2T devices to the router, the second one can never login to it's server.  If I load the line 2 of either device with the other account, the second line can not login to it's server.
Ideally, I would have just one PAP2T connected using line 1 and 2.
How do I set up line 2 with the other account?
Thanks,
Joe

Hello,
sounds like some of the ports may have been blocked.
May you test those simple tests :
1) Swap ports 5060 and 5061 between Line1 and Line2 - watch which line will register, if any ...
2) IF line with port 5060 registers (Line2) and line with port 5061 (Line1) NOT, may you contact your Internet provider (ISP) if for any reason the port 5061 is blocked, also you may contect the VoIP provider, if registration FROM port 5061 is also accepted ...
3) You may try "nasty trick" and setup SIP ports totaly crazy - for example 5261 and 5262 - or simply any two numbers. There is, in fact, no restriction on SIP SOURCE port (just uzus, that those are USUALY 5060 and increasing), SIP DESTINATION port is (almost) alwayws 5060.
I use my SPA-1001 on with ports 5261 and 5262 on Line1/Line2 with no problems.
