Hi All, I'm running into a reoccurring nat issue, phones (Linksys, Polycom or Cisco) behind a cisco router, 2600 series, ios 12.4. Sometimes 2 or more phones will have the same outside port number and will register to Asterisk with the same port number. As far as I can tell this is only occurring with the SIP port, not RTP ports.
To resolve, I have to go into the router and clear the translations for one if the phones, restart the phone and it nails up a new nat session on a different outside port in the router. This seems to happen more often after some power failure on site, when many phones reboot at the same time. This has happened various times at different customers, large and small, different phones, different Asterisk servers. The only thing common in all cases is the cisco routers. We have tried different IOS releases as well. So I'm pretty certain this is an Cisco IOS bug or maybe a router overload? I've searched for a cisco nat bug with no luck. So my question is, has anyone else experienced this type of issue and if so, is there a solution to resolve? Thanks.
