break dial tone

We inherited a VoIP deployment with 30+ 908 gateways that have repetitive issues. Currently, at least once a week a gateway has ports on it that are unable to break dial tone. Our current solution is a weekly reboot of every gateway. Firmware has been updated as well as changing codecs. In house wiring has been verified.

Re: break dial tone

I'm assuming that you're referring to analog FXS ports, if not please advise.

Is it possible that some of the connected devices are configured for pulse dialing? The TA908 series doesn't support it, DTMF only.

Re: break dial tone

If you are still looking for an answer to this, I had the same issue on TA 924s running 12.3.4 firmware. I downgraded mine to R12.3.1.E and the issue never occurred again. At the time of downgrading, Adtran support had stated the issue was present in 12.3.4 and would be fixed in a future release to it is possibly fixed by now.

Re: break dial tone

Have a client this just happened on today. 924e (3rd Gen) running version R13.2.3.E. All the configured FXS ports could not break dialtone when they started to dial. Needed to reboot to resolve.

Re: break dial tone

I opened a case RQST00004992334 with support and they are investigating it further. It appears to be a bug but has not been identified fully so their dev/eng folks need more debugs prior to the 924s ending up in this state so they can write a fix into upcoming firmware revisions.

Re: break dial tone

Was there ever feedback on this? We also experience periodic FXS failure on several of our customers. The analog port won't produce dial tone and inbound calls won't ring on the customer's side yet the debug of the FXS appears normal ringing.

Reboot is usually the only solution and it's typically happening on one port at a time.

Re: break dial tone

The incoming calls ring and the term side goes off hook. I hear dead silence and the call does not progress. If I reboot the ADTRAN I know for sure everything will be fine. Then weeks later it will happen again. No audio. The analog ports will like "lock up" and I've never been able to figure out why. Idk what testing to do.
