I've just recently started having this problem as well. It only happens sometimes, but when someone will call into an IP phone through a PSTN gateway, instead of hearing 3 or 4 rings (before voice mail) they will hear one continuous ring for the entire duration of time before transfering to voice mail.
CCM Version 3.09
I dont know the topology but I ran into this same problem when setting up a PRI try this. Notice the dot after incoming called-number
dial-peer voice 2 pots
incoming called-number .
You mean the PSTN caller is hearing a "long ringback" tone?
If that is the case and you are using a 2600 or 3600 series router, you need to run 12.1(3a)XI5 or later in the XI train, and that should fix the problem.
Let me know if you are using a different gateway type.
I have been experiencing the same problem for a couple of months now. We have a VG200 gateway. Is there an IOS fix for the VG200's yet?
You think the XI will fix this problem on the AS5300 as well ?
We have the same problem. The PSTN caller is hearing a "long ringback". It got better after I put the 'incoming called-number .' on the voip dial-peer. Sometimes it works fine but sometime for example every 3rd ringback er long (the PSTN caller hears two normal ringback, one long, two short and so on).
We are running AS5300 with E1 connected to the PSTN. IOS 12.1(5)T8
One of our dial-peer looks like this:
dial-peer voice 5590000 voip
incoming called-number .
progress_ind setup enable 3
session target ipv4:10.10.10.10
Dave, it would be great if you had some BUG ID for this problem ?
As mentioned in my posting in June 19th we are having the same problem with our AS5300. We just upgraded it to 12.1(5)T9 which is the newest release in the T series but it did not fix the problem.
I don't have the bug ID handy right now, I am sure one could be given to you if you called TAC.
I don't think the long ringback problem has been fixed in the 12.1(5)T train. You would need to use 12.1.3a(XI7) which is the latest in the XI train and should have the fix. Again, a question for TAC.
I could not install the XI series because then our CallTracker/Syslog would not work.
Cisco Norway recomended I installed 12.2.1a for my AS5300 so I did and everything is working great. We now have a normal ringback :-)
ps. the id is CSCds41380
We also test the version 12.2.1a, for an AS5300, and we have the problem of the continuos
ringback, is not a problem present all the time, but in some moments the caller hear a long
ringback. We began to expirienced this problem when we installed the IVR co-resident in
the Call Manger.
Does anybody knows which version fix this problem?
