[asterisk-users] Odd issue CentOS 7 vs Ubuntu 20.04

[Jerry Geis]

So I have CentOS 7 server running asterisk 18.8.0 - all is good.

I unplug that server - plug in a ubuntu 20.04 server at the same IP address.
let my 3 devices reconnect to the ubuntu server....

When I pick up the polycom phone and dial it connects.
I hear the other ends 'tone" - but when I press digits - nothing happens
(to select a port)
Seems everything is set for rfc2833.

The devices are a TOA SIP Gateway, and a TOA N-8000 device connected to the
GW.

I have compared the settings of the polycom extension on both boxes - they
match and also the SIP gateway.

I tried to compare the sip debug from the Ubuntu to the centos and "looked"
the same to me.

Where might I look next or what might I look at ?

Thanks,

Jerry
