It's been my experience that when asterisk does a dns lookup, for externhost or to do a SIP register, it blocks the whole server. Not sure if 1.6 has that problem or just 1.4 though as my internet has been stable while im awake these days<br>

Hi<br>
<br>
I am in the process of move a company from pstn to an asterisk setup.<br>
<br>
They had 2 pstn lines - only really needed a max of 2 previously.<br>
<br>
Now I have installed a tdm410 to handle the cross over from pabx to voip<br>
handset. this has been done, the tdm is now just used to provide a<br>
backup pstn line - only used as a last resort for outgoing calls - as<br>
its shared with a fax line.<br>
<br>
<br>
I use 2 voip providers one primarily for local and std and the other for<br>
mobile calls, all though they can be backups for each other. and then<br>
the pstn line<br>
<br>
originally i had (and still till i get around to changing them) macros<br>
to dial each interface and macro's that handle trying each voip and then<br>
pstn in order, this is based around dialstatus (hackled from the<br>
website).<br>
<br>
My problem is when I have had long adsl problems (pain in the back side,<br>
back to base alarm system) eventually asterisk seems to not want to talk<br>
to the voip phone - nor does it allow any calls to be placed.<br>
<br>
my guess is this<br>
srvlookup=yes<br>
<br>
which I had until recently - decided I don't really need it, my guess it<br>
asterisk has a problem with name resolution and get stuck, but stuck<br>
such that call processing can't happen.<br>
<br>
snippet of my macro<br>
<br>
<br>
[macro-dial-sipmnf-sippt-pstn]<br>
;<br>
; Enter with these<br>
; ARG1 = number to dial<br>
; ARG2 = timeout value<br>
; ARG3 = flag determines if hangup or return on no answer<br>
; HR = hangup and return (default)<br>
; RT = return without hangup (must set)<br>
;<br>
; Returns with FOUNDME = DIALSTATUS<br>
;<br>
