I have configured my MGCP gateway to register with my CUCM. However, only calls from CUCM is successful whereas calls from simulated PSTN fails.
Please find attached debugs and gateway configs.
Appreciate your comments. Thanks.
Hi, the called number received from simulated PSTN is "Called Party Number i = 0xC1, '5553003' " but your extension is 2003 not 3003. that is causing the issue.
If you configure 3003 instead of 2003, it would ring the phone. Please check.
I only got it working if I change the external phone mask to 2XXX and the DN to 2XXX, but I wanted to use DN 3XXX as it will differentiate my HQ phone from my BR phone
Basically my HQ uses DN 2XXX, with external mask +555115552XXX, BR uses DN 3XXX with external mask +665215553XXX, if I call 5553XXX, it will fail, however, if I change it to 2XXX for both DN and external mask it works. I am also getting confused.
External mask is nothing to do with inbound calls.
can you check if there is any translation pattern (beginning with 555) to convert the number from 5552XXX to 2XXX?
What I guess is, instead of passing only 4 significant digits, all digits are received & processed in CUCM.
I thought translation pattern is call from CUCM phones to PSTN. Correct me if I am wrong, my knowledge in voice not that good, I could not see any translation pattern beginning with 555. As for Called party transformation pattern, I could see some pattern,
\+55511.XXXXXXX with predot discard digits.
and calling party transformation pattern with
also with predot discard digits
it is now better to collect CCM traces for a test call for BR site. also collect the debug isdn q931 log from the MGCP gateway at the same time.Please include the calling & called number.
Without going deeper in problem (we already have so much confusing info ) - why don't you just replicate HQ translations which you mentioned for your BR location with appropriate modifications?
Both the ISDN and ccapi is for outgoing.
