[cisco-voip] FXO port ignore battery failure

[Norton, Mike]

A station port would need to supply talk battery to the station, so yes that would need FXS, but no that's not what I want.

Basically I was trying to get a dry audio output for an overhead paging system. Kinda like you would with an E&M port, but I only have the FXO ports. The idea was for this to be a temporary workaround - contractor is installing a new paging system to replace a failed one but they are missing the module they need to interface with a telephone port, so in the meantime all they can accept is a dry audio feed.

Anyway, it is now looking like the paging contractor will be able to get the proper module they need by Monday, so I'm not going to bother trying to do the temporary workaround and I'll just do the normal FXO way next week.

I just want to ask why? The situation you're talking about makes me think of end stations, in which case you'd want to have an FXS port, not an FXO

I need to send a call out an FXO port that does not have talk battery or dialtone on the other end. Normally an FXO port will notice the lack of talk battery and the call will fail. Is there a way to configure the FXO port to not check for talk battery? This is on a 2900 running 15.3M.
