Does anyone have an example FXO failover configuration for the NetVanta 6000 Series gateways? I had configured this a couple of years ago from some documents that were on the old kb.adtran.com site and I can't seem to find those same documents again. I am running transparent proxy on a NV 6334 with Polycom phones registering to our Class 5 softswitch. I am wanting to provide POTS survivability for 911, etc. in the event the phones lose connectivity to the softswitch.
David,
Thanks for the follow up, I ended up opening a service request on this and was able to get it setup and working. Below are some of the key commands that helped...
voice trunk T01 type analog supervision loop-start
description "FAILOVER"
connect fxo 0/1
rtp delay-mode adaptive
codec-list Default
voice grouped-trunk FAILOVER
description "FAILOVER"
trunk T01
accept 911 cost 0
permit proxy
voip name-service host sbc.xyx.com sip udp
ip sip proxy emergency-call-routing proxy
ip sip proxy emergency-call-routing accept 911
domain-proxy failover
Cwallace,
Thanks for posting! The SIP Proxy Survivability feature is built in and works just by configuring a separate voice trunk on the unit. Assuming all of your SIP proxy configuration is complete, below is an example of adding an FXO trunk.
voice trunk T10 type analog supervision loop-start
blind-dial
connect fxo 0/0
!
voice grouped-trunk ANALOG
description "911 and survivability"
trunk T10
accept $ cost 0
!
ip sip proxy emergency-call-routing accept 911
The last command shown is optional. This command forces all 911 calls to always use the FXO port. Also, the FXO port numbering, 0/0 is shown, may be different depending upon which unit, module slot, and specific port you are using. Feel free to respond to this post if you have further questions.
Thanks!
David
