The setup is based on cucm 8.0.2c & 2 x vg (at 2 different site) using h.323<br><br>1 vg is based on 15.0(1)M1<br>1 vg is based on 15.1(2)T<br><br>Both of them display the same characteristic when doing outbound call to PSTN while inbound call is not affected by this issue. <br>
<br>When 1 x isdn channel is used(taken) up, others cannot make outbound call at all.<br><br>When in SRST mode, both vg with their individual ISDN connection can receive inbound and outbound call from PSTN normally. <br><br>
Currently my interim solution is to allow all the phones to stay in SRST while trying to find out the root cause. <br>I'm able to replicate the problem by allowing my CIPC to connect to the
callmanager and make 2 x outgoing call to my mobile. First one will go through while
second call will get disconnected for some unknown reason. I noticed about this temporary failure issue but what bug me is nothing goes wrong when so many phones are in SRST mode right now. <br><br>I have attached the debug isdn q931 configuration. <br>
