[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}.

ast_channel_alloc() in main/channel.c
---cut---
if (ast_strlen_zero(ast_config_AST_SYSTEM_NAME)) {
ast_string_field_build(tmp, uniqueid, "%li.%d", (long)
time(NULL),
ast_atomic_fetchadd_int(&uniqueint, 1));
} else {
ast_string_field_build(tmp, uniqueid, "%s-%li.%d",
ast_config_AST_SYSTEM_NAME,
(long) time(NULL), ast_atomic_fetchadd_int(&uniqueint,
1));
}
---cut---

Er, sorry, I thought a bit too far. That is for the UNIQUEID.

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.

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
