Hi Everyone,

I have a server with Elastix 1.6 between a PBX Panasonic D500 and Telco.
For Span 1 connect to Telco (ETB- Colombia), on Span 2 connect to PBX.
Calls from Telco work successful. On the other hand, I try to call from
PBX and always shows  "MF back cycle timed out".

Local plan is 7 digits, National plan is 10 digits, International plan
is 16 digits and Toll free is 12 digits.


S.O. Elastix     1.6-2 x 64bits
Asterisk          1.4.26.1
