[Freeswitch-users] destination_number cleanup

[Elliott Vogel]

Some custom softphone a call center we use has; they auto dial with it and I was able to make brea, x-lite and polycom phone (using uri dialing) send some messed up strings too. I was trying to see if breaks the sip specification so I could push back but I couldn't find anything what a uri couldn't use. It looks to me it can be almost anything - personally they are being lazy and not scrubbing the list first

Thanks for the regex string and I will look into writing a script however I would prefer not too...

Yes, this is really broken input! I thought it was bad some do +1 or 001 1 or no prefix to dial America!

To modify Ryan's code to make it more flexible...

^(?:\+1|001|1)?\D*(\d{3})\D*(\d{3})\D*(\d{4})$

$1, $2 and $3 should give you the full number, so bridge to 1$1$2$3.
it will match anything that has xxx-xxx-xxxx with whatever separating non-digits is in between.
But it can only handle (by discarding) a prefix of +1, 1, or 001.

I'd suggest using xml_curl or a lua script and doing a regex replace of any non-digit characters, if you really need. But how in the world is this your input? What devices are sending this??

Why do you have broken devices sending you numbers in that screwed up format in the request URI in the first place?  At this point you should be using XML_CURL then cleaning that up if this is what you're hitting.  Or you tell your clients to fix their badly broken behavior.

I was wondering if anyone has a regex expression that works to return
just digest? I have some clients sending requests formatted to +1 (555)
555-5555, 555-555-5555, 555.555.5555 which aren't be processed  by our dial
plan because we are expecting all numbers (5555555555) ****


How about this?

^\+1\s+\((\d{3})\)\s(\d{3})-(\d{4})$|^(\d{3})-(\d{3})-(\d{4})$|^(\d{3})\.(\d{3})\.(\d{4})$

$1, $2 and $3 should give you the full number.
