[cisco-voip] ARQ - ACF source signalling IP Address question cube - gatekeeper call routing

[Thorsten.Mayr at barclayscapital.com]

Just wondering if somebody has come across this and if this is by design
or not...

 

Scenario:

 

PHONE -> CUCM (A) -> GK (A) -> cube (A) -> cube (B) -> GK (B) -> CUCM
(B) -> PHONE

 

Cubes registered to the Gatekeepers respectively.

Routing is H323 and voice (voip) dial-peers.

CUCMs are registered to the GK's respectively.

 

All is working fine, however looking at the ARQ's  received on GK(B)
they have the source signalling IP address of the cube (L).

My understanding would be that this is a new call leg and I would expect
to see the IP address of cube(B) in it.

The corresponding ACF from GK(B) back to cube (B) is being sent to the
IP address of cube (B) which is what I would expect.

 

Also looking at Cube (B) I can see the ARQ (still same seq number) with
the srcCallSignalAddress of Cube-A.

 

 

I have a case open with HTTS - but was wondering if somebody has come
across some detailed documentation RFC alike reg. ARQ's etc. on Cisco
equipment. 

TAC/HTTS could only point me to the standard doc's on CCO which do not
discuss/disclose any of the details but only high-level GK design and
command references.

 

Any comments / directions / hints / links welcome. Or maybe this is by
design after all... 

 

Thx

Thorsten
