[asterisk-users] transfers from an E1 using 2b-channel or similar anyone? (QSIG?)

[Manrique Feoli]

Hi Matt,  thanks for your answer,
I guess it is still as you said a while back that you did it using 5ESS

Can you share how you did in 5ESS?  (a sample of the extensions.conf ) 
   and what kind of switch you were connected to?

I'm not sure if the  Alcatel 4400 and the Nortel Meridian 11 supports 
5ESS,  but are willing to find out.

thanks

Manrique
