Level 1

hi all,

not sure you can help me on this,

i have issue with Voice GW routing calls, issue like

1.normal PSTN call new office, i receive ring tone in the pstn phone and 7942 phone. however when i pick up the 7942 phone the PSTN phone just keep ringing almost like no one pickup the 7942 phone.

2. 7942 call out pstn, no ring tone in the 7942...my mobile phone get the office callerID and when i can pickup the phone but no voice on neither phones, then around 10 secs later, mymobile auto drop out. 7942 start with busy or bi bi bi bi signal.

here is some background.

i am installing a new office for our company which involve new gateway for the office.

i have setup the call manager part, which i have successfuly tested with Route list pointing to a existing gateway. everything fine.

any ideas?

thanks in advance.

The ring tone you hear when you pick up the phone is a recorded sound built into the firmware of the IP phone.  Its NOT the PSTN tone.

You may have an overlap somewhere, which is why you do not hear the dial tone from PSTN.

Dial slowly and listen.  For example:

Dial 9

What do you hear? (or outside number)

then the next number

next number

eventually it show up.

hi tcalinins

thanks for the reply,

i have tried dial slow and when i dial the outside number (0) here, i get

the 2nd dial tone. then keep dial the digits with no play back. once dial

the last digit, the pstn phone start to ring. (still no ringtone sound in

VOIP phone) however once i pick it up. both side have no sound.

i'll check the route plan again also GW see if anything obvious..

cheers

Sounds like you have a couple things...

When you dial the last digit, the PSTN gets the call, but still do not hear ring back.   Since its h323, there seems to be a ring back issue on the h323 side.

Check this out

https://www.cisco.com/en/US/docs/ios/12_3/vvf_c/voice_troubleshooting/old/vts_h323.html

couple things to run through.

But also, since you are not hearing audio on either end, but the call is up, you have a codec transcoding issue.   When the call is connected, hit the ? twice on the IP Phone.  You shoudl be able to see the sending and receiving codec is going on.

thanks for all the help,

i think i miss to mention the GW was behind a VPN link.

and during another troubleshooting , some of the h323, skinny inspection has

been turned off. reenable the inspection all good now..

thanks

Jon
