[cisco-voip] cucm 6.1(2) and h.323 issues !!!

[Djokic Sinisa]

hi group..

 

 

we're facing some audio issues in our CUCM 6.1(2) to h.323 gateway
communications..

inbound calls are facing the following problems:

 

1. PSTN caller calls IP phone - inbound call

 

if fast start ISN'T turned on in callmanager admin page, we're having 2-4
secs delay between the moment audio can be heard..

no audio is lost..

 

 

2. PSTN caller calls IP phone - inbound call

 

if fast start IS turned on in callmanager admin, we're having normal call
establishment without delay, BUT, let's describe it this way..

if PSTN caller counts from 1 to 5, IP phone person can hear 1, but 2 and 3
are lost, and then 4,5 can be heard and everything afterwords is fine..

so some 2-3 secs of call is lost, but not the initial one, but after first
or second second of call..

 

so, did anybody faced this problem..

 

all the config is classic, dial-peer macth, h323 bind address, voice rtp
send-recv, codec match, no network delay or congestion etc..

 

 

 

any thoughts or should i contact TAC..

 

 

thanx..

 

 

 

regards..
