Hi all

I have run a scenario with 2811 cisco router (PVDM2-32 and 2mft2-t1/e1) 

2811 is connected to ISP to receive 5 digit 79063 from outside and also 2811 is connected to panasonic TDA100D via a PRI/e1 link 

 called number = 79063

calling number  = 8907161493

sip provider ip address : 172.123.101.165

 

TDA100D----(PRI-link)---->2811----(SIP-trunk)----Huawei softx3000

 

the problem is incoming call from ISP to 2811 rings but drops.....

  

here there are sh run , debug ccsip message, debug ccsip  calls, debug idsn q931 ,debug ccsip error ,

debug voice ccapi inout

debugs are based on a call from outside calling number is 8906171493 and called number is 79063

 ios version is 15.0

 

 

would you please help me to solve the problem ? 

thanks in advance
