[Yazen Alaa]

Dear All

I have CUCM ver 8.6 and H323 gateway (E1) , the problem is :

PSTN Number or mobile number A calling ---> cisco phone ext :  851 then transfer to---> PSTN number or mobile number B ---> aroung 4 rings then the call disconnected and no hearing on each other

result is PSTN number or mobile number B is ringing and when i open the call , the call is ringing for around 4 rings after that the call disconnect and we cant hear each other

how to solve this issue ????

Note : I did create MGL , and it is assigned to Gateway and device pool and phones and it is configured on voice gateway as showing you in show run

and MTP in enabled in voice gateway configuration in CUCM

please your answers are very important for me

thanks all

Hi Kayyali,

Please provide the debugs of ISDN Q931, further I would like to know, whether the phone rings when the call is transferred from the CUCM to external number, we cannot proceed further without knowing the reason for call failure, please paste the gateway configuration in the CUCM side, was this working earlier ?

cheers,
