Looks like the bug associated with the intraregion codec parameter that
should be changed to g729

Hello Brain ,
can you check what DP assigned to your MTP and what codec is being
used in there ?
Thanks

Hello -
The call flow I am working on looks like this
hq-phone(sccp)->gk->cube->cme-phone(sccp). I am working on Vol 2, Lab 1,
Sections 4.2 and 5.1. The requirement in 4.2 is to "ensure supplementary
services are working on UCM and UCME" while routing calls through the
GK/CUBE. My gatekeeper controlled trunk on UCM is in a g729 only device
pool. Calls are working as expected up to this point.
Here is a sh gatekeeper calls while a calls is in progress from UCM to
UCME
(I am using 16K from UCM to GK and 128K from CUBE to UCME, Life is good):
siteA-rtr#sh gatek calls
Total number of active calls = 2.

I proceed to setup an IOS MTP using G729 put this in an mrgl/mrg, assign
to
HQ and BR1 and G729 only (GK Trunk) device pools and check the "Media
Termination Point Required" checkbox on the Trunk. I also put the UCM
software mtps in an mrg so they would be hidden. Finally, I set the BRQ
enabled flag to "True" in UCM Service Parameters. Calls from UCM to UCME
are still successful and now my supplementary services on UCM are working
as
well.
My show gatekeeper calls is the same as above after I enable my MTP.
Then, I proceed to question 5.1 where it states to "ensure the gatekeeper
can only allow 2 calls between the UCM and UCME" using the command:
bandwidth interzone zone UCM 32. I have multiple zones UCM and UCME per
the
lab requirement.
My calls fail every time now, in both directions. I did a "debug h225
asn1"
and see that the admission request and confirm are requesting "160" or
16K
of bandwidth for calls to Gatekeeper. When I remove the bandwidth
interzone
command from my gatekeeper config, calls work again.
Here is my gatekeeper config:
gatekeeper
zone local UCM ipexpert.com
zone local UCME ipexpert.com outvia VGK
zone local VGK ipexpert.com
zone prefix UCM 1... gw-priority 10 gk-trunk_2
zone prefix UCM 1... gw-priority 9 gk-trunk_1
zone prefix UCM 1... gw-priority 0 siteC-rtr
zone prefix UCME 3... gw-priority 10 siteC-rtr
zone prefix UCME 3... gw-priority 0 gk-trunk_1 gk-trunk_2
zone prefix UCM 5... gw-priority 10 gk-trunk_2
zone prefix UCM 5... gw-priority 9 gk-trunk_1
zone prefix UCM 5... gw-priority 0 siteC-rtr
zone prefix UCM 9*
gw-type-prefix 1#* default-technology
bandwidth interzone zone UCM 32
no shutdown
If anyone could shed some light onto what the problem might be, that
would
be great. Thanks!
