Phones registered but cannot call
Hi,
I have configured one voxalot on sipura 1001 and the other in a different city in the device Grandstream HT496. Both the phones are registered but many a times I get the extension you are dialing is not available. Same goes true if a person from other city calls me from his HT496. What could be wrong. I have tried the NAT possibilites but it did not work. Sometimes everything works fine (with lots of hangups). Please suggest. Thanks |

A very few routers will need NAT_Keep_Alive_Intvl set at 119. If 119 still doesn't do the job then try 59. Of course you also need to make sure your Internet connection is reliable, and that your IP address is not changing frequently. |

Thanks for the reply.
Well in the SPA 1001 I have the most of the settings as specified below. However, there is one thing which I cannot control and that is the IP address which changes every 24 hours (by the ISP). I will make the necessary changes in the SPA device as you have mentioned but how do I put a check on the frequently changing IP address?? Can you please throw some light on it ?? Thanks once again.

Try a different router. If another router does not retain the public IP address from day to day then you should restart the router and ATA at a daily time when you are not expecting calls, perhaps sometime at night would be good. Be sure to restart the ATA each time you restart the router. It might help to power the ATA and router through a timer which turns power off/on once daily. If that measure is not sufficient you could also set "Register Expires:" as low as 600 in order to track the changed IP address more quickly.
