sometimes ok and sometimes not ok......

hi,

I got a problem about mgcp GW and CUCM routing.

E1*2 DID------MGCP GW---------CUCM

all the ip phone are registered to the CUCM, and it is always ok for outbound calls from the ip phone to PSTN.

but when the PSTN call the DID numbers , sometimes ok and sometimes not ok......about 50% to successed.

I called the ISP to check the phone line, and they said they have sent the cg and cd number to the GW, and it seems no response, so the call failed.

and I can get the cd and cg number for the GW by debug isdn q931 both the call successed and not, so i think it maybe not the problems of ISP.

I have checked the isdn status, the L1 is active and line 2 is multiple established.

I checked the mgcp registered information and it seems ok.

and I checked the CUCM cpu status, it is about 5% usage.

and I checked the active calls number in GW, it is about 12, and i thought it is ok for E1*2

and I changed another E1 line (there are three E1 in the router) last Friday, it is not a DID line, and it is provided by another ISP,

I entered the following command for a translation.

voice translation-rule 3
rule 1 /.*/ /2288/

voice translation-profile 3

I and shutdown the this E1 line and all the dial-peer, but when PSTN call the DID numbers, it is also sometimes ok and sometimes not ok.

I known my english could be better, but I hope you can understand what i said and you can share some advices with me.

thanks in advance.

You need to start by degugging the GW to look at exactly who is disconnecting the call and what's the reason code.

hi java,
thanks for your prompt reply,
I am MGCP packet code and I will use the debug mgcp packet command to find the disconnect reason tomorrow.
is there any other useful debug/show commands that I should use in that case?
thanks.
yu.
