How does two BE3000 works?

[Nico Yang]

Hi,We have two BE3000 in different city, their network is connected as VPN.

BE3000 system:8.6.4

PSTN: spa 8800

I want two city call each other as VOIP, is it can be done ? and how to config ?

The BE3000 supports SIP trunking  across BE3000s (multiple networked BE3000 as a distributed call  control). See "

Multi-Systems Cisco BE3000 Solution" under http://cisco.com/go/smartdesigns/uc

I am assuming that you know that the BE3000 is EOS.

Hi , Navin X Albert ,thanks for your help,the Documents "Multi-Systems Cisco BE3000 Solution" is very useful, I can call each other  via sip trunking now...

And now I have another question,  Can I call remote city's PSTN Number over  remote's BE3000 system when I at local ?

If it can be done,can you teach me how to config ?

And I find another bug, when  I add  a PSTN connection----add FXO

Choose Service Provider    Service Provider : Cisco-analog-FXO  /Cisco-analog-FXO-China 

When choose Cisco-analog-FXO ,the system works fine, PSTN can call in, AA is work.I also can call out via SPA8800.

When choose Cisco-analog-FXO-China, when  PSTN  call in,  AA does not work,but I can call out .

So you are talking about Tail End Hop OFF (TEHO) across clusters. It is possible. You would need to play around considerably in the Advanced Dail plan section. But it is not easy nor supported.

Regarding the bug, we would appreciate if you open a case with Support. Thats the only way it gets fixed!

To configure you need to go to Sites and Advanced Dial plan:

Once you get there all the rules are very similar to CUCM dial plan:
