Digium IP Phones - Teleworker Capability?


We couldn't see anything about this on the Digium site, but maybe
someone here can comment? Do the new Digium phones provide good "teleworker" functionality? The benchmark we're comparing against is the capabilities of Mitel
3300 IP systems with Mitel 5330 IP phones (running their proprietary
MINET protocol), specifically: a. A Mitel phone can be easily configured for teleworker mode (select
TW mode and the IP of the gateway server). The phone reboots and it
is ready to be used (once the Mitel border gateway is set to recognize

Skinny Channel Driver Remote Crash Vulnerability


A previously developed patch dealt with a denial of service attack exploitable in the Skinny channel driver that occurred when certain messages are sent after a previously registered station sends an Off Hook message. Unresolved in that patch is an issue in the Asterisk 10 releases, wherein, if a Station Key Pad Button Message is processed after an Off Hook message, the channel driver will inappropriately dereference a Null pointer. Similar to the problem solved with the previous patch, a remote attacker with a valid SCCP ID can use this vulnerability by closing a connection to the Asterisk server when a station is in the "Off Hook" call state and…

RTP traffic on its IPv6 address as well. Between the user agent and the

asterisk with ss7 voice broadcast


Asterisk under > 90% load of SS7 calls can only withstand the voice
broadcasting for 30 minutes. After around 30 minutes, it stops receiving
any call hits via AMI. No errors are reported. Giving it a minute's rest
makes it work for another 30 minutes. Can anyone hint to what may be causing this?
