| Im having a problem in one of our callmanager clusters. This cluster
has one H323 gateway connected through an E1 digital trunk to this
particular provider.
When users dial some long distance calls, the PSTN provider takes too
long in returning a ring back to the gateway, the user then hears a
fast busy tone rather than a ring.
This problem happens with this provider only, we use other PSTN
providers in our others clusters and we dont experience this problem
when dialing the same long distance numbers.
I have opened a Trouble Ticket with the PSTN provider and they have
told me that our PBX is disconnecting the call too soon, and that our
PBX should give them some more time before assuming the call could not
be completed.
My question is, is there a way to increase the time a gateway waits for
a ring back from the provider? Is this a CallManager configurable
setting or is it an IOS setting? I guess it is an IOS setting, but I
cant fugure out which one is it, I dont seem to find anything related
in dial-peer configuration mode.
Many thanks for your help.
