Forward Problem in T2 Link

[jcalvillo]

Hi everybody i have a question about using NPRAE Link with a cisco callmanager, this is a link that works in both sides but when i make a forward in an alcatel station to other alcatel station and someone call the extension forwarded the call doesnt complete and finally releases, I put a trace to identify the issue but the only thing that i found is that the cisco calling number have 5 more digits inserted than the extension who initializated the call and i think it could be the cause of failure, but im not sure because the call can be completed if the set is not forwarded, someone have any idea?
Alcatel Rel 6.1.1 (f2.502.33.a)


this is the real case: Ext 4099 in cisco calls to Ext 8323 in alcatel that is forwarded to station 8335 and the trace show this:

[root]

from the trace it seems to be that you use QSIG and the CCM can not handle the diversion facility send
by OXE, you told him the set is forwarded unconditional to ext. 8335, what have the CCM to dial into
the OXE? Maybe you must add a prefix in the NPD for this network.

Or you switch from QSIG to ISDN than the OXE handle the forward localy or you upgrade the OXE
then you could disable the diversion facility.

Ok Thank you root i will try to contact CCM manager to check this

Hi,

It seems that you have qsig connection via PRA to Cisco. Could you please post yout OXE configuration here, because I have the problem, that Cisco in unable to disconnect its extension. Did you have any problem like this? I am also using R6.1.1.
