I try to call from the phone behind 881 to the phone behind 2911. phone is ringing. but when I picks the phone I hear a busy carrier on both sides.
and on the 881 I see:
Mar 26 10:21:28.524: //-1/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/CCAPI/ccIFCallSetupRequestPrivate: Bad argument: vdbPtr != NULL
don't know where to dig.
i have 2 clusters. the cluster above (with MTPs on 881 and 2911) and cluster 2 (with MTPs on ther 2911s). and I have intra-cluster RSVP locations too. and I have the same problem when trying to call to/from the phone behind 881.
is it the limitation of voice IOS on 881? or what?
