SPA 122 stops working with both PHONE 1 and 2 lights flashing

Hi,

We have hundreds of units deployed and we start having complaints that the line isn't working anymore while the unit does register with our server. Any calls going to the ATA gets a USER_BUSY condition like if a line was offhook but that's not the case.

Anyone had this condition? I am running 1.3.1(003).

One common thing so far is the fact those users do faxing but we ruled out config since we enable T.38 on all of them regardless.

Since the unit registers, we can't rely on the REGISTRATION too much so would like a way to figure out if the unit is healthy or not.

Thanks,

Benoit

Please update to 1.3.2(014) and see if this resolves the issue.

The 1.3.2 did not fix the condition since it turned out the FXS ports were somewhat fried; not visually but electronically.

The impedance on LINE1 was around 32 ohms and both lines were not producing the -48Vdc so it is definitely a hardware problem (could be caused by overheated condition).

Thanks
