[asterisk-ss7] F on the end of the number

Thu Jul 26 07:59:43 CDT 2012

Hi, 

I have a ss7 connection with a TDM SWITCH (ERICSSON AXE). I can receive calls, but I can't make outgoing calls. 

I receive a rel 21 from de far end. 

I check this problem with my telco, and the telco said I'm sending the F character on the end of the number. 

See the log of the ERICSSON side:

On the NB column we can see the number that the ERICSSON received from my libss7: 0151136001019F

But, I make a debug in my side and I didn't see the simbol F on IAM:

Maybe the F is the # my libss7 send: 0151136001019#

Asterisk 1.8.10.1
libss7 version: 1.0.2

Can I disable this F ?

Is it hardcode? Anyone knows how can I change this?

Thank you so much!
