Hi Cisco Support Community,
we have a call from a remote destination (mobile phone - ive replaced by 160xxxxxxx as a DN to anonymize) of an internal DN, to an internal DN (ive repolaced by 99xxxx as a Dn to anonymize).
The DN 99xxxx is busy and the remote line gets the busy after 30 seconds of "silence".
What can be the cause of this problem?
See the attached txt for q931 debug.
Can it be the same issue as here:
