[asterisk-users] Slow to get dialtone when going off hook - big problem for me :(
Hi All... My Asterisk system uses VoIP and also 2 POTS lines from Cox Communications. Recently, the dial tone presentation from Cox seems to have slowed, so it can take as long as 3 seconds to get a dial tone. The problem I am having is that Asterisk does not seem to wait for the dial tone when dialing out. I'm using zaptel T400 cards. Is there any way to configure it such that I can insert a delay between the time the card goes "off hook" and the time it starts dialing? Alternatively, can I make it wait until there is a dial tone? Incoming calls are just fine, so I am almost certain this is what's happening. Thanks! Jim

Inserting multiple w's as others have mentioned only seems to work with Tone dialing as well, which is OK for 95% of the people. Of course you still have to guess at the number of w's, and as Cox gets slower, you will have to go back and insert yet another. No one seems to be interested or skilled enough to fix this. It's much more fun to add new wiz bang features than to fix some fundamental design flaws. John Novack

You can also use wait exten => X,1,Wait(3) ( for 3 secs ) On 13/11/06, Jim Archer <jim@archer.net> wrote:> > --On Sunday, November 12, 2006 11:53 PM -0500 John Novack > <jnovack@stromberg-carlson.org> wrote: > > > > > Dovid B wrote: > >> <snip> > >> How hard would it be to have asterisk detect a dial tone ? > > I really can't say.
