| 22:02.27 | putnopvut | So, let's say that I wanted to generate a random URI for a SIP endpoint to use as the request URI when subscribing to a call completion service.

The host would be the sip_pvt's ourip.sinaddr, I suppose, and the port would only be present if a |

| 22:07.43 | Kobaz | i'm not sure what caused it, but here's the whole bt of that thread: http://pastebin.ca/1697250 |
| 22:08.11 | putnopvut | seanbright: kpfleming: Actually, I'm not trying to use an existing username with this URI. Basically, I'm trying to come up with a unique string such that when the SUBSCRIBE comes in, I can match the incoming subscription to a specific failed call. |
| 22:08.46 | putnopvut | I could even use the call-id from the failed call as the username portion, I suppose. However, that would be easy to exploit, I'd think. |
| 22:08.49 | seanbright | i was saying that you might match an existing username unintentionally |
| 22:09.02 | putnopvut | oh, so I read your suggestion in reverse :) |
| 22:09.04 | kpfleming | right, i understood that |
| 22:09.08 | seanbright | unlikely, but possible. |
| 22:09.17 | seanbright | not sure that is necessarily a problem |
| 22:09.31 | kpfleming | i would suggest just using a UUID, since that's your best shot at having something unique |
| 22:09.44 | putnopvut | gotcha. Is there a function in Asterisk to generate a UUID? |
| 22:09.49 | kpfleming | there could be |
| 22:09.51 | kpfleming | i don't remember |
| 22:09.51 | putnopvut | heh |
| 22:09.54 | russellb | there is not |
| 22:09.55 | seanbright | there isn't |
| 22:09.57 | file | dejavu |
| 22:09.59 | putnopvut | mkay |
| 22:10.09 | seanbright | there is a reference implementation in the rfc |
| 22:10.23 | seanbright | which i started to integrate at some point |
| 22:10.26 | putnopvut | Yeah, but that's a hassle. I'll try to find a public or license-compatible implementation. |
| 22:10.28 | seanbright | but then got bored of it |
| 22:10.37 | putnopvut | And use that. |
| 22:15.47 | putnopvut | All right. Thanks seanbright and kpfleming for the help. I can at least get a suitable skeleton written for the random URI generator now. |

| 23:56.13 | kpfleming | yep |

| 23:57.01 | russellb | :-) |
| 23:57.12 | kpfleming | well, there are also ffs and ffsl |
| 23:57.18 | kpfleming | the 'll' part just means 'long long' |

| 23:57.35 | kpfleming | yep |
| 23:57.37 | russellb | it is to find the lowest bit set |
| 23:57.42 | kpfleming | exactly |
| 23:57.48 | kpfleming | returns the index of that bit plus 1 |
| 23:58.17 | putnopvut | Interesting, when I think of the "first" bit set, I would have thought most significant, not least significant. Interesting. |
| 23:58.20 | kpfleming | there are also clz and ctz |
