I am currently operating a very simple configuration on a fresh install of asterisk 1.2.0b1. I have a linux host with a 2.6.13 kernel and a TDM400 PCI board installed with an FXS module on port1, and FXO module on port4 (the way it came from digium). I prefer the large gap between ports while getting used to the hardware to prevent woofing any equipment, so no problems there.
I have the simple configuration working as cited on digium’s tdm400 online documentation, and everything is working pretty much exactly as I had expected, minus one little gotcha:
Of my two analog phones, only one will physically and audibly RING when the ring signal is sent out Zap1-1 according to the console output. The phone that rings audibly also happens to be a set-top corded phone; nothing fancy, a sony IT-M602; AKA run-of-the-mill $80 consumer 2-line phone with a few features. The callerID, cdr/mysql database logging and everything else works great as well.
Then, i switch (not add, substitute completely) to a GE model 27936GE-M, which to save you any obscure lookups is a fairly run of the mill $100 consumer 2.4Ghz cordless phone. In this phone’s case, when the Zap1-1 port rings, the phone will pickup the CLID information properly, and can even pickup and communicate flawlessly, etc. The only problem is, this phone will not audibly ring !! Neither the base station nor the handset, in any configuration of defaults and [un]docked status, ringer(s) (handset/base)=1/0, 0/1, and 1/1. 0/0 not much use I’ve been searching the digium, asterisk, forums and google(rand) sites for hours and hours now and just can’t locate a cause. The REN on the GE phone is listed as “0.4B”, the Sony phone that DOES work does not have a printed ringer equivalence, oddly. I have not taken the time to measure current across the phone line during ringing as the results will not open any new t/s’ing avenues, regardless.
So, i’ve come to wonder, is the 4-pin keyed molex connector coming from my Antec PC power supply providing the needed voltages ? My PS-Molex connector is
keyed |/~1~2~3~4~| where 1=red=5v, 2=blk=gnd, 3=blk=gnd, 4=yellow=12v.
I believe i’ve exhausted all configuration options and am looking at a Current-shortage problem; however I am unable to find the simple 4-wire schematic for the tdm400’s power connectors, which is frustrating me to no end [lest i not have to write this post and fix the problem NOW!!].
Anyhow, I apologize if I’ve missed anything obvious but if I did, it wasn’t bourne of lack of effort I promise you. My spatial awareness and research skills have become horribly frayed after hours of EVERY configuration iteration I could think of.
So, a schematic, or a POSITIVE ID of the power posts on the TDM400 board, or some other sort of insight as to why I am getting sporadic results across various analog phones as to whether they audibly ring or not ? I must sleep, but due to all other functions working properly EXCEPTING audible ringing, my money is on ringing=current=s/5v/12v ???
Thanks! LOVING the asterisk software and the hardware is admirably robust as well! I plan to tout these heavily at client sites without my managers knowing I’m helping clients to save hundreds of thousands of dollars in proprietary ware… the true irony is in that which I cannot divulge, but I promise the irony is delicious…
