MGCP with FXO not able to make the call establishement.

HI,

Please help me in the below scenario-

I have 6 Analog Lines and I have tested that all is working with Analog Phone, i can able to make and receive calls.

But when I plugged the Analog Lines in to the FXO Ports and found when somebody dials any of the Analog line number (Phone number)  can receive the call at the connection-plar number but when I tried dialing out my call is going out but I am not able to hear any tone that call is connected and the receiving end phone rings , when the he/she picks the call , no voice is there and receiver disconnects the call but my VG keeps dialing him with another number (Out of the 6 alog line number), but the moment my call goes out with 02-702-0563 (Analog Number) then my call get connected and both party are able to communicate. Only this is the only number which is able to make the call establishment. I have tried to put that line into other FXO port but wherever the line is, call is able to establish with that particular number only.

the Voice-port configuration is below

voice-port 0/0/0
supervisory disconnect dualtone mid-call
supervisory answer dualtone
timeouts call-disconnect 5
timeouts wait-release 1
timing hookflash-out 50
connection plar 32301

MGCP is often source of much trouble.

Revert to H.323 with trunk-groups and it will be working fine.

Note without configuring custom disconnect tones, that will never work.

Hi,

Can you try this :

1/ Enable caller ID in each port : caller-id enable

2/ Remove the conexion plar in each dial-peer

3/ Add this dial-peer for each voice port (FXO or FXS Voices only)

for example :

dial-peer voice DP_Nbr pots
service mgcpapp
port 1/0/0


Last : Verify if ports are in loopstart or gorund start. I think this should not create problems.

Best regards,

Antra
