Hi everybody,
we've got a CUCM 7.1.5 here with a 2901 router as a voice gateway that has a VIC3-4FXS/DID in it. The ports on the VIC are registered with the CUCM via SCCP using stcapp. The users at the attached phones have been experiencing the following problem for three months: When they are dialing a number, some digits aren't signalized to the system. We can verify that by debugging voice ccapi and voice application stcapp. This happens on random digits, primarily on other ones than the first one. The issue has shown up without any configuration change (as far as I know), and the same construct works fine in other locations. Is it maybe a hardware issue like a faulty VIC or DSP?
Thanks,
Peter
