[asterisk-users] are channel names unique
Hello ppl, Are the channel names generated on 'Dial's supposed to be unique? I see the channel names repeating on my asterisk box. I just wanted to confirm this. Can anyone point me to the lines of code where the channel name is generated/calculated? I tried looking, but it looks like quite a big maze.

Channel names are not guaranteed to be unique at all. However, all channels have a uniqueid associated with them. You can access it in the dialplan via ${UNIQUEID}. -- Russell Bryant Senior Software Engineer Open Source Team Lead Digium, Inc. ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

That is for the UNIQUEID. Grüße, Philipp Kempgen -- Asterisk-Tag.org 2008, 26.-27.

Re: [asterisk-users] are channel names unique
So I thought!! Thanks guys. But a query with regards to this : I need to send hangup commands based on these channel names only. So at any given point of time, for 'n' ongoing calls, will these 'n' channel names be different/ unique? If not, using AMI, how do we hangup a given channel? cheers - Ben. --- On Thu, 5/15/08, Russell Bryant <[EMAIL PROTECTED]> wrote: > From: Russell Bryant <[EMAIL PROTECTED]> > Subject: Re: [asterisk-users] are channel names unique > To: [EMAIL PROTECTED], "Asterisk Users Mailing List - Non-Commercial > Discussion" > Date: Thursday, May 15, 2008, 11:46 AM > Benjamin Jacob wrote: > > Are the channel names generated on 'Dial's > supposed to be unique? > > I see the channel names repeating on my asterisk box. > I just wanted to confirm this. > > Can anyone point me to the lines of code where the > channel name is generated/calculated?

While channel names are not unique over time, at any given point in time, there should not be more than 1 channel with the same name. -- Russell Bryant Senior Software Engineer Open Source Team Lead Digium, Inc. ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
