Have checked to make sure you do not have tip/ring reversal?
Also confirming these are loop start not ground start?
Does your PBx have any attenuation control (not gain)?
The telco can attenuate the line some but it can be a pain to convince them.
It could also be a bad ground. If you can check that, we used to dump a
gallon
of water on the ground stake (at the Network Interface)and it would go away

we have been working with fortinet on a customer who has been
experiencing alot of echo from the sip PBX on the analog line, there
is no direct control of the gain, they have provided multiple firmware

lines.
Is there a mechanism like a x-ohm resister on the tip or something to
that effect to lower the volume or whatever the appropriate term is?
our next step is to just get an ata to run the analog lines into to
feed the pbx a controlled line, however im concerned this may just add
another level of fuckery to the mix
