    Most probably this happens because your provider is quite loaded and has a noticeable delay in processing of your request. Calling phone is ringing, because of PBX server has accepted your call and passed it to provider. But called phone is not ringing until the provder processes the request and places the call onto PSTN network. If you hang up calling phone at that time the request will be cancelled at 3CX PBX immediately, and cancel request will be passed to the provider, but provider can miss it or ignore it and continue to call your PSTN phone. That is why it is busy after that.

    Thanks for your sugesstion but i don't think this is what happens since the phone is still busy and I havent touched it for at least 3 hours. If I connect the VoIP phone directly to the sip provider i dont get any delays and it is working fine.

    regards

    Delay

    I have this same problem. The internal ext I"m calling from starts ringing then after about 3 or 4 rings it actually STOPS ringing and then the outside line I am calling starts to ring.

    If I answer, the call is completed.

    Hi,

    Does the callee ever ring before the caller hangs up ? or does this happen only when the caller hangs up. in other words; have you tried leaving the phone ringing for a very extended period of time?

    In the mean time thanks for the provider name, we will add this to the list of providers to test. Maybe we can see if there is a particular issue with the way this provider works.

    Thanks for your feedback!

    This is the scenario -

    I call my cell phone via ext 100 on the PBX. The Ext start ringback. Cell phone still not ringing. Ext gets ringback 2-4 times. Cell not ringing. Ext QUITS getting ringback, Cell phone starts ringing.

    Cell phone will ring to cell phone voicemail. I hear cell phone voicemail on ext.

    With my provider supplied SPA-2000, this doesn't happen, I get ringback and cell rings right away.

    Would you like screen shots of how the provider has my SPA-2000 set up? I know the admin password and could do that.

    I got to thinking; we had problems with getting double ringback when we first set up our service with Quantum Voice. Maybe the Sipura-2000 is providing ringback and the provider is not? I'll email them and ask.
