[asterisk-users] Configuring modem pools in Asterisk

[Joshua Kinard]

Hmm, I don't know if the zaptel fax detection will trigger.  This is going through my company's Rolm CBX switch, using a plain T1 cable (yanno, RBS, E&M Wink, and all that jazz) between the two systems as a Tie line, so that may mess with the fax stuff.  The Rolm's just wired to take a special extension block and pump anything coming in on them out the T1 trunk group to the asterisk server (which is only being used for fax purposes as a T1 bridge to iaxmodem/hylafax).

My initial tests were using the 's' extension, because the other T1 card was mangling the DTMF signaling due to a hardware incompatibility -- the replacement card lets things work properly, and asterisk hunts for an exten line starting with the first digit of my extension group, not 'fax'.  Though I can probably do '_55XX' as my extension definition versus '_X.', since my extensions are four digits long and there's only 100 of them...

I'm assuming in the provided example, the priority value 'n' simply illustrates where I need to add 2, 3, 4, etc..., as a quick glance at voip-info.org's explanation doesn't indicate that 'n' is valid.  Not sure what the |20 in the Dial() function refers to, though...

Thanks for the pointers!  A few friends said asterisk config files were horrific, but they're actually not bad at all, TBH (BIND zone files have far worse syntax).

It should look more like this:

exten => fax,1,Dial(IAX2/iaxmodem1/${NumberCalled}|20)
exten => fax,n,Dial(IAX2/iaxmodem2/${NumberCalled}|20)
exten => fax,n,Dial(IAX2/iaxmodem3/${NumberCalled}|20)
exten => fax,n,Dial(IAX2/iaxmodem4/${NumberCalled}|20)
exten => fax,n,Busy()
