Hi everyone,
I am working on a Toll-Bypass project that involves two Cisco MC3810 routers
connected each with an Avaya Definity PBX G3Si via a channelized T1
interface. Both Cisco routers are VoIP dial-peers across the Internet cloud.
I am able to make VoIP calls between analog phone1 and phone2 connected to
the routers (see ASCII layout below).
So far I haven't had much success making VoIP calls between a digital phone
connected to the PBX and an analog phone connected to routerB (nor routerA).
If anyone has implemented this type of configuration and can offer some
assistance, I'd be happy to forward further information, such as captured
debug and show command outputs, configuration files and diagrams for further
analysis.
Here is a simple layout of what I'm trying to implement:
------------------------------------------------------------------
analog analog
phone1 phone2
| |
Digital-----[PBX]~~~~~[RouterA]========[RouterB]------analog
phone ^ ^ ^ ^ phone3
| | | |
cat3 CT1 Internet FXS-port
------------------------------------------------------------------
Below, there are relevant VoIP configuration lines on both routers:
