INFO message

Problem Description: When a call coming from

 

 

 

should be used for

IOS gateway and terminates to IP phone and

 

 

 

ringback tone

is being transferred, the caller is not hearing

 

 

 

generation for IP

the second ring back tone (cscds11354).

 

 

 

phone call transfer

Change has been made in both call manager

 

 

 

 

and IOS gateway to use h225 user info

 

 

 

 

message to send the q931 signal IE to request

 

 

 

 

the IOS Gateway to turn on and off the ring

 

 

 

 

back tone. But it turns out that the older

 

 

 

 

version of H.225 standard (dated 02/98) had

 

 

 

 

typo error in session 7.3.6 which stated User

 

 

 

 

Information message should be used, and the

 

 

 

 

latest H.225 standard (dated 11/00) corrects

 

 

 

 

the error by stating that Information message

 

 

 

 

should be used.

 

 

 

 

In order to correct this problem, both Call

 

 

 

 

Manager and IOS gateway needs to make the

 

 

 

 

change at the same time to use the correct

 

 

 

 

message type, there is a ddts cscdw39337

 

 

 

 

opened to keep track of this problem for the

 

 

 

 

IOS gateway, therefore these two ddts are

 

 

 

 

dependent on each other.

 

 

 

 

Since the user information message is being

 

 

 

 

only used between Call Manager and Cisco

 

 

 

 

IOS Gateway at this time, there is no

 

 

 

 

immediate impact on the original functionality

 

 

 

 

and the functionality of both products, but we

 

 

 

 

should use the correct message in the near

 

 

 

 

future.

 

 

 

 

Workaround: None. This has been fixed in

 

 

 

 

CCM 3.3

Need CLI to disable

Currently IOS enables TCP keepalives on the

 

 

 

h225 TCP keepalive

H225 VoIP call control session. This cannot be

 

 

 

timeouts

disabled. These keepalives, zero byte tcp

 

 

 

 

packets, are sent each minute and will tear

 

 

 

 

down the tcp session after 4 attempts which

 

 

 

 

clears the call. The noticed symptom is that

 

 

 

 

calls in progress are dropped after 5 minutes if

 

 

 

 

these keepalives are not acknowledged. The

 

 

 

 

TCP keepalives may be blocked in certain

 

 

 

 

circumstances such as: - while running the

 

 

 

 

VoIP gateway in SRST mode and the WAN

 

 

 

 

link to the CallManager fails - traversing

 

 

 

 

firewalls which may be blocking the TCP

 

 

 

 

keepalives In the latter case, this should not

 

 

 

 

occur but has been noticed in some cases.

 

 

 

 

Workaround: None
