[asterisk-users] Cordless VoIP Phones and Access Point hand-off?
I have a situation where we have an asterisk box that is extending several Mitel PBX extensions to some cordless SIP phones (Cisco WIP310). Everything works great, except when the cordless phone walks out of range of one access point and into range of another (cisco 1100 series APs). I've been able to get virtually seamless roaming between access points to work in the past with data but have never tried it with voice before. Is there a way to get asterisk to keep the call active for a certain period of time even after the phone becomes un-reachable then re-attach it when the phone comes back, or hang it up if it never comes back? For instance, keep the call active for 30 seconds after the phone becomes un-reachable. if it comes back in 30 seconds, re-attach the active call. If not, hang it up. Barring that, if the cordless phone becomes un-reachable is there a way to automatically put the active call on hold, or park it? That's not the preferred solution, but it would work great until I figure something else out. Thanks in advance -------------- next part -------------- An HTML attachment was scrubbed...

It shouldn't be disconnecting the call. Do you have rtptimeout or something? Qualify=x? You could try disabling both these options. -- Cheers, Matt Riddell _______________________________________________ http://www.venturevoip.com/news.php (Daily Asterisk News) http://www.venturevoip.com/exchange.php (Full ITSP Solution) http://www.venturevoip.com/cc.php (Call Centre Solutions)

When I walk out of range and then back in the call is usually still there. I've not tested past that so it might hang up after an unknown timeout. Ira

Not sure if you are issuing DHCP at the access point or from a central control From a central control should allow seamless roaming within different APs, assuming easy auth to the AP, the only issue you get is when the handset dithers between choosing signals from one or the other, and thats not that common. If your auth to the AP is simple e.g. wpa2 (something the phone can handle with no effort) and you have DHCP centralised then the phone should move happily (depending on your phone). We had a WISP Cafenet in Wellington with open access and you could keep a call up walking along the street. The DHCP was centralised so no reauth between APs or reregister (as you change ip addresses) required, just connect and carry on. You could get a couple of km down the main streets if you had a need to talk that long.
