I am trying to implement failover with bandwidth.com so I did research on google and found the steps to do it.
They were:
First SIP Trunk
Outgoing Dial Rules
Outbound Dial Prefix : +
Outgoing Settings
Trunk Name : BW-SIP-A
PEER Details :
canreinvite=yes
dtmfmode=rfc2833
host=216.82.224.202
outboundproxy=216.82.224.202
progressinbound=yes
qualify=300
type=peer
disallow=all
allow=ulaw
Incoming Settings
USER Context : from-bandwidth-A
USER Details :
type=peer
reinvite=yes
port=5060
insecure=invite,port
host=216.82.224.202
fromdomain=216.82.224.202
dtmfmode=rfc2833
disallow=all
context=from-trunk
canreinvite=no
allow=ulaw
qualify=300
Second SIP Trunk
Outgoing Dial Rules
Outbound Dial Prefix : +
Outgoing Settings
Trunk Name : BW-SIP-B
PEER Details :
canreinvite=yes
dtmfmode=rfc2833
host=216.82.225.202
outboundproxy=216.82.225.202
progressinbound=yes
qualify=300
type=peer
disallow=all
allow=ulaw
Incoming Settings
USER Context : from-bandwidth-B
USER Details :
type=peer
reinvite=yes
port=5060
insecure=invite,port
host=216.82.225.202
fromdomain=216.82.225.202
dtmfmode=rfc2833
disallow=all
context=from-trunk
canreinvite=no
allow=ulaw
qualify=300
Configure Outbound routes
Now you need to add 1 Outbound Routes
Route Name : US-Canada
Dial patterns :
911
1NXXNXXXXXX
1NXXNXXXXXX
etc …
Trunk sequence :
SIP/BW-SIP-A
SIP/BW-SIP-B
Configure Inbound routes
Description : John Doe
DID Number : +12025081234
Destination : Choose an extension, IVR, Queue, … (what you want …)
When I change my Trunk Name from bw_outbound to bw_outbound_pri, it breaks incoming calls. The error I get is:
NOTICE[30818] chan_sip.c: Call from ‘bw_outbound’ to extension ‘+XXXXXXXXXX’ rejected because extension not found.
I do not understand where it is getting bw_outbound when I changed it.
Outgoing calls work fine with no problems.
Thanks
