Greetings,
I m beating my head against the wall with this one folks.
We have deployed a TA 924 to a customers site. It is termination for a SIP trunk established on our SBC. Here is how it flows.
Inbound call to DID >INVITE SBC > SBC INVITES Softswitch > Softswitch INVITES service port > service port invites public resource (public wan IP) on SBC > SBC Invites the TA 924 > TA924 Voice Trunk to FXO ports
Everything works, with exception to the voice ring-group. When I dial the ring group number, it rings linear to the first unit and then the next. However, when I try to pick up the call, I get a dial tone.
Here is the config.
hostname "Example"
enable password woot
!
clock timezone -8
!
ip subnet-zero
ip classless
ip routing

!
ip domain-name "xxxxxx"
ip domain-proxy

So, the only thing I cannot configure correctly is the voice ring-group. Both phones ring if in "ring all" type or linear, but when the call is picked up, the phone provides a dial tone.
Any and all assistance is very highly appreciated.
