ISA550W & PAP2T can't connect to SIP

[Jack McNeil]

Hi, I can't seem to get a PAP2T working with a ISA550W router. The pap configuration interface is sending SIP Messages but doesn't get any responses, registration state: can't connect to login server. After changing the SIP port manually for both lines on the pap it works until I'm getting a new WAN IP from my ISP.

Already tried it with ALG support on/off, port forwarding, firewall permit for the device on all ports. The PAP is on a fixed IP.

Thanks for your help

Dear Jack,

Thank you for reaching Small Business Support Community.

It's been several days with no advice or suggestion from the community members on this Small Business Security forum, therefore I suggest you to either move this post to the proper Voice and Conferencing community forum from the "Actions" panel on the top right corner of the page, or open a new discussion on the same forum;

https://supportforums.cisco.com/community/netpro/small-business/voiceandconferencing/ata

I wish we could be a better help at this point but I am sure we can better assist you from the mentioned support group and please do not hesitate to reach me back if there is anything I may assist you with in the meantime.

Kind regards,
