QuoteI also would like to route outbound calls to the OBi202 using a prefix like <8:>1xxxxxxxxxx
First check that this is really needed. Most voip service providers will allow you to make outgoing calls without the need for registration. It may be easier to set up a VG on the OBi1032 using the same credentials as the ones used for the relevant OBi202 spX.
If you really want to use this sort of setup (OBi202 sp2 as example):
OBi1032 >>> OBi202sp2 >>> voip service
Then I suggest this setup, which I believe will be new to most readers here:
OBi1032
Physical Interfaces > PHONE Port > DigitMap:
( ... existing rules here ... |8(Mabc)| ... existing rules here ... )
Physical Interfaces > PHONE Port > OutboundCallRoute:
... existing rules here ... ,{(8(Mabc)):spX}, ... existing rules here ...
User Settings > User Defined Digit Maps > User Defined Digit MapX >
Label: abc
DigitMap: ((xx.)<:@192.168.1.10:5061>|xx.'@192.168.1.10:5061')
spX = lightly used OBi1032 sp
192.168.1.10:5061 = ip address:port of OBi202 sp2
OBi202
Voice Services > SP2 Service > X_InboundCallRoute:
{>(<8:>(Msp2)):sp2},{ph}
CallerID and CName is passed using this method, but that is not relevant here as you will want to use the credentials of the service set up on sp2, which the OBi202 will do automatically so long as you have not enabled spoofing.
