Dear alll,

I have an asterisk PBX installed on a client. All the calls goes to a
Ring Group, which strategy is "Ringall". My problem is when an
incomming call goes to this Ring Group, all phones start ringing, but
when I answer the call from one ringing extension, the other
extensions continous ringing, but if I answer any ringing phone, no
one is in the line, cause the first extension had answered the phone.

How could I make when an extension in the ring group answer a call,
the other extension in the ring group stops ringing?

Thanks in advance.

VoipCrazy.

This is sounding like a NAT or routing issue. Assuming you've
implemented the ring group by "Dial(SIP/100&SIP/101&SIP/102)" or
similar, Asterisk /will/ stop ringing the other phones when the call is
answered.

Do you have any firewalls or routers between your Asterisk server and
your phones? If so, have you configured the SIP extensions with
canreinvite=no and nat=yes?
