Hi:
This is your scenario: hq <--(1)--> pstn <--(2)--> br1,
Let say for example hq call br1 via AAR, 5002 call 1002, if there isn't enough
bandwith and AAR is enable, 5002 will take 1002 EPNM
6178631XXX, plus AAR prefix 91 -> 916178631002 -> this should match a router
pattern in partition that phone AAR css should see (9 should be stripped) this
route pattern should point to PSTN, if the call is droped as it try to ingress
at pstn (1) the the problem is that the the number 16178631002 is not a matchin
an outgoing dial-peer to BR1, if the call fails at it egress from the pstn (2)
then the problem is that the called number you are getting from pstn is not
matching a number at CCM (probably a css problem, significant digits, etc are
incorrect). For example if significant digits is set to 4 and css of gw can see
5002 the called number should be set to 5002 and match the dn
Same apply in the opposite direction
I don't know the detail of your ccm (EPNM, AAR prefix, css, etc) neither the
pstn details, so first isolate the problem between (1) and (2) and then just
check the pstn dial-peer and the called number you get at (1) and also the
called number you get at (2) and the br1 gw config related to called number

Hi Angel,
Thank you for your response. I am little bit unclear with what you want me to
do.
I thought when you call between sites, you dial 91 + the 10 digit number. So,
if I am calling from HQ (5002) to BR1(1002), I will need to dial 916178631002,
correct? Also, I changed the AAR number on the BR1-Phone 2 to 6178632683
(PSTN-BR1 #) and it works fine. As you said, it looks like the BR1 RTR does not
like the 10 digit format. But, BR1 RTR being a MGCP G/W, I can't use dial-peers
to format the incoming called number and I thought when I look for 4
significant digits on the BR1 G/W incoming call handling, it should take care
of this.
I have the EPNM = 6178631XXX and for AAR mask , I tried both 6178631002 and
blank.
I also tried this. Called from PSTN HQ # to 6178631002. When the call comes
into BR1 G/W, on the debug isdn Q931, it comes in as 8631002.
Thanks

Hi guys,
I was working on lab 6A to set up AAR between the HQ and BR1. I was successful
in setting the rsvp, reducing the bandwidth and forcing the call to use AAR and
go over the PSTN. I was able to complete the call when i call from BR1 (1002)
to HQ (5002). But when I dial from HQ(5002) to BR1(1002), I get a busy tone
and the dreaded "Unallocated/Unassigned isdn message on BR1" I have css-br-ld
as the incoming CSS on the BR1 RTR and that css has pt-internal. 1002 is
assigned pt-internal. I am not sure what I am missing here.
Here are the debug outputs from HQ and BR1 RTR.
