RE: about ReserveValue

Hi Kevin

The new version doesnot allow multiple m= lines in a
session description. 
Just to confirm - if you are implying that RG value
shall apply in case multiple session descriptions
(delimited by v= line and each containing a single m=
line) are specified in LOCAL descriptor.

best regards,

RE: about ReserveValue

Right.  Multiple m= lines requires multiple session descriptions.  RG
would apply to these, as multiple descriptions in a single descriptor
(Local *or* Remote) would be potential alternatives.

Single action request with multiple action responses

Dear Megaco members,

Is the following response message allowed from the standard point of view?

MGC sends the MODIFY to MG:
T=1{C=-{MF=*{...}}}

MG responses with multiple actions sharing same ContextID:
P=1{C=-{MF=T1, MF=T2}, C=-{MF=T3, MF=T4}, C=-{MF=T5, MF=T6, MF=T7}}

Or the question can be asked as: Is the multiple action response allowed for
a single action request? Any part of H.248 standard addresses that issue?

Regards
Gillian

RE: Single action request with multiple action responses


HI Gillian,

H.248 does allow you do give the action response in the way which you
have specified. However you cannot do the same if you are asked for a
wild carded response. 
It is always recommended to group all the commands for a particular
context in an action in the following way which avoids message overload.

P=1{C=-{MF=T1, MF=T2, MF=T3, MF=T4, MF=T5, MF=T6, MF=T7}}

Regards
Karthik

How to decode H.248 messages



Hi all,

I am working on H - 248 Megaco messages for now. And I wonder if there is any tool which decodes H - 248 Megaco messages (text), that is which makes them understandable for all people with sufficient technical background.

Do you have any knowledge on this?

Regards

Omer

RE: How to decode H.248 messages

Hi,
 
I am taking the logs by using Ethereal or simply by connecting to Gateway Controller. For example I have taken the log of two way call. Its something like:
 

00:03:56:41.10[T:4]Received msg <-- GW IP[124.53.34.25] GW PORT[1984]

!/1 [124.53.34.25]:1984 T=20551{C=-{N=ROOT{OE=1519{it/ito}}}}

 

00:03:56:41.10[T:4]Sending msg --> GW IP[124.53.34.25] GW PORT[1984]

!/1 [124.53.34.25]:1984 P=20551{C=-{N=Root}}

 

...

 

What I meant by saying `how to decode H.248 messages` is that how to make those text messages more understandable (user friendly) for all users.

I have asked that question to you because I know that there is such a tool for c7tu logs. It is a perl script which takes c7tu logs and some other parameters as input and returns a user friendly log as output.

Thanks...

Omer

RE: Single action request with multiple action responses

Actually, the intent is that a single action request requires a single
action response.  An action request using a wildcard for the context is
the same as one action request for each match to the wildcard, and may
therefore generate multiple action responses.  The exception to this
would be when using the segmentation added to V3 -- but then the
duplicate actions would appear in different messages.

Re: some questions on rfc3264 and ts29.232

Hello Albrecht,

Your comment 2 is not entirely correct. H.248.4 Corrigenda 1 states:
"To provide interworking between MTP3B and SCTP, and to allow for flexible 
implementations of gateways and controllers in order to offer efficient use of 
SCTP associations, the M3UA layer may be added on top of SCTP."

Regards, Christian
