I been testing my clients installation for any problems with the farsouth
gateway and what I noticed is that the calls are being dropped at transfer.
I found that when the reception hits the transfer button on her sip phone, the
caller gets a dialtone and the reception goes on hold. Very wierd problem.
Ive disabled senddtmf and astdtmf in misdn.conf , that seems to have solved the
problem. Any insight on this.
