ext101 Posted February 6, 2008 Report Share Posted February 6, 2008 Can anyone please help? Drop calls happen in the middle of conversation, sometimes as soon as 1 or 2 minutes in, and on some cases calls do last 8 to 10 minutes before it gets cut. We are just doing plain SIP to SIP calls, using a windows machine. Even with only 2 users on their calls this happens. Thanks a lot! Quote Link to comment Share on other sites More sharing options...
ext101 Posted February 6, 2008 Author Report Share Posted February 6, 2008 After doing test calls it looks like its not actually a dropped call, but instead the caller (pbxnsip) cant hear the called party --- like a one-way audio --- but the called party can still hear the caller.

Vodia PBX Posted February 6, 2008 Report Share Posted February 6, 2008 The best way to track this problem down is to use Wireshark and record a conversation. Typically, those kind of problems are because of NAT or firewalls. Also silence suppression can be a problem. A wireshark trace will show it.

ext101 Posted February 6, 2008 Author Report Share Posted February 6, 2008 Thanks for the link. Would putting the pbx on the DMZ, or assigning it with an public IP, thus exposing it to the internet lessen this complication? Right now I only have port-forwarding rules on the firewall.

Can't wait until we have IPv6 rolled out, then there is no more need for this kind of address recycling! Quote Link to comment Share on other sites More sharing options...
