Yes, I was suspecting it was something like that. I bought a 33-ohm
resistor (1/2 watt) and it fixed the problem. Both modules are working
properly now.

According to the Ohm's law, the loop's overall resistence was 188.46
ohms, once I was measuring 4.9V and 26mA in the circuit. By adding 33
ohms, it went to 221.46 ohms, bringing the current down to 22 mA.

Excellent article and telephony stuff. Bookmarked!

Thanks for the reply. Have a nice day.
