asterisk users - Mar 2005 - asterisk outbound to SIP provider problems (still)

Hi

I am using cvs and updating it every couple of days Unfortunately I am still 
getting a 20 second timeout on  sip calls placed to various providers, can 
anyone see anything wrong from sip debugs? Or have any ideas what the 
problem might be?

Cheers

Walt

destination: pickup

caller: 2 way audio ok
destination: 2 way audio ok
caller: Sip code 183 (Never 200 connected etc)
caller: audio stops

destination: chooses to hang up
