Vodia PBX Posted November 17, 2010 Report Share Posted November 17, 2010 There is a flag in the extension setting where you can demand from the PBX that the user has to press "1" in order to accept the call. This solves the problem that the cell phone mailbox picks up the call. Apart from that, you need to make the mailbox timeout long enough so that your carrier is able to call the cell phone before the PBX mailbox kicks in.

Nutel Posted November 24, 2010 Author Report Share Posted November 24, 2010 Hello, The First problem is not calling an extension/mailbox/ of the PBXnSIP. It's when calling out of the PBXnSIP to a customers cell phone that the call drops just before there cell phone greeting starts to play. Second is during a call it drops. They hear static and it drops. I don't know if it is a Registration Expiration or Session Expiration Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted November 24, 2010 Report Share Posted November 24, 2010 That sounds like a major problem with the SIP trunk. Are you using a PSTN gateway or a SIP service provider? When does it frop? 30 seconds are typically a sign that there is something wrong with the signaling. If you can, get the SIP messages that the PBX exchanges with the termination device/provider.

Nutel Posted November 24, 2010 Author Report Share Posted November 24, 2010 Is there a keep alive feature? Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted November 25, 2010 Report Share Posted November 25, 2010 Not sure if the keep alive is the problem here... There was two-way media obviously, for about 17 seconds. Dropping the call at that time is very unusual. Can you try another service provider or a PSTN gateway so that we can be sure that this is a problem with this service provider? Also, the SIP packets should be in the attachment of the email, they would be of great interest as well. Quote Link to comment Share on other sites More sharing options...
