Summary:                    Incoming Call with E&M signalling is not working
properly. (AsteriskNow 1.4.9.)
Description: 
We have a TE220 card configured with E&M signalling on AsteriskNow 1.4.9.
Asterisk communicates via this signalling to a Adtran TA604 (an IAD). This
IAD exchanges MGCP messages with a switch where MGCP test lines are
provisioned.
             ______            ________            __________
            |      |          |        |    E&M   |          |
Cisco7960---|  Sw  |---MGCP---| Adtran |T1------T1| Asterisk |---SIP_Phone

  -->       |______|    -->   |________|    -->   |__________|   -->


When we try to place an incoming call to the SIP lines on Asterisk, and
error is occurring as following:

-- Starting simple switch on 'Zap/25-1'
[Feb  1 13:34:30] WARNING[4621]: chan_zap.c:5630 ss_thread: getdtmf on
channel 25: Success
-- Hungup 'Zap/25-1'
asterisk*CLI>

We saw that there was a bug for a similar problem, but specifically for
E&M Wink. For us E&M Wink also worked, but we do need to use E&M only.
