[c-nsp] voip over multilink issue

Mon May 7 12:19:01 EDT 2007

Hi 
You don't realy give us alot to go on . 
12.4T implemented  some new voip stuff, did you try 12.4 mainline? 
The mainline is based upon the 12.3T code so try that first. 
Otherwise you need to run some debugs and find out where the problem lies.
Debug isdn q931 to see the isdn signalling 
Debug voip ccapi inout to see the h323 packets.

Regards
Brian

Subject: [c-nsp] voip over multilink issue

hi 
one of my customer has 7206 vxr router. 
I installed pa-2fe card into this router and we got crash problem when the traffic goes through this card. and i decided to upgrade the ios
after upgrade the crash problem was fixed. but this time the voip connection with the remote office was lost even the data connection is ok. and i tried another ios same thing happened. we reset the siemens centrals but problem was still going on.  But the interesting thinh in the headquarter we can call pstn and bla bla. but only voip with the branch was fail.  And i downgrade the ios again the old one. And now voip is ok but again pa-2fe makes crash.

promlem can be because of the remote office and HQ office ios incompatibility? any idea pls?

thanks a lot

currrent  ios
disk2:c7200-is-mz.123-11.T5.bin   (pa-2fe problem  but voip is ok)

tried ioses
c7200-advipservicesk9-mz.124-11.T1.bin   no prob with pa-2fe but voip issue
c7200-spservicesk9-mz.124-11.T1.bin       no prob with pa-2fe but voip issue

design   is 

branch siemens pbx--  branch router  >>...multilink interface connection <<.....headquarter 7206vxr-- HQsiemens.
