Vodafone assured us that the removal of POTS would be painless as the modem ports would mimic the copper lines, "nothing will change they said, Howver the standard double ring pause pattern has changed to single ring longer pause single ring. This is causing the PABX to drop and then pickup the line meaning you can only take a call when the phone is ringing, is this a normal occurence ? Can Vodafone change the ring pattern, I am not sure how it is created, we would have to get tech's over to reprogram the PABX. Would appreciate any advice.

You need to set the ring validation timer to 3 seconds. NEC PBX?

I doubt vodafone would do anything about it, you pbx tech may be the best bet.

If you pbx supports SIP that would be the best way to go.

Thanks for the quick response. I think it is an Erikkson LG, I have logged into the consul but it is extremely complex, kind of hoped that we could revert back to a standard ring pattern, Vodafone teck suggestd 61 but that seems to be for voicemail. I dont know if the ring pattern is generated in the adsl modem or at the exchange(are there still exchanges?)

Thanks

Speak to a PBX tech this is not a service provider issue

Hi Linux

Thanks for you comment.

The pbx was working fine until they (Vodafone) removed the POTS telling us that the two ports on the modem would replace the analogue phone lines with no changes in our setup, appears there was a change with a longer pause between rings which I assume means that pbx thinks the call is gone and another call is coming in on the next ring, from other comments I can see that there are settings that will compensate for this but I cannot see why they are unable to restore the original settings which would solve the problem with no additional costs.

Your PABX sounds old, I would suggest replacing it with a new system and SIP trunks or a cloud PABX

@slaw54 Technology changes and you need to move with the times so one questions how old is this PBX?

@Linux

Not sure, was installed 2 to 3 years, not on site right now but maybe IPECS 1000? phones are marked Ericcson LG. Had a quick look on online and IPECS manuals seem to infer that the default off time is 600 m/s and the pause in ringing seems closer to 1 sec. I will see if I can get someone on the mainland to talk me through it if it is just a setting, still cannot really understand why a provider would make such a change without any notification and the unable to advise if it is possible to change it back. we can dial out as normal so I have just put a conventional phone on port one of the modem until its resolved.

Thanks for your help.

We install and support the IPECS UCP100/600 series PBXs but only with SIP trunks, we no longer support analogue or ISDN trunks

Sounds like you're going from VOIP trunks to analogue off a ONE NZ ultrahub, then back to VOIP handsets past the PBX which sounds really messy.

They never upgraded the modem its the old rectangular flat one with the LCD and buttons on the front and two phone ports on the back so now all of our broadband and phone comms is dependant on an old copper line and an old modem. The whole POTS thing has been a bit of a nightmare. We will see what tomorrow brings.

Cheers

The PBX that I think he has based on the limited information I have in this thread supports SIP Trunking, however when it was installed the installer didn't take the time to move the POTS lines over to VOIP and just used analogue trunking.

I possibly put this down to the installation could have occurred when ADSL was only PPPoA 0/100 rather than newer PPPoE 0/110 with tagged priority traffic which is an absolute must with VOIP over ADSL given the limited upstream bandwidth.

All very good talking about VoIP etc but the root cause is that Vodafone has botched the ring cadence on the new system.

It is Vodafone (or ONE) who you need to refer this too.
