VG 320 Static on call

[Nikhil.ranjan]

We have a VG 320 and we have a paging system configured on the one of the analog ports. Suddenly we see that the paging has stopped working and when some one dials the paging number, we get a ring and then static. Here is what we have observed. 

voice service voip

fax protocol pass-through g711ulaw

modem passthrough nse codec g711ulaw

h323

  emptycapability

sh voice port summary

--  fxs-ls      up    dorm on-hook  idle     y

When I run the show voice call summary, I get Codec and VTSPState only on the affected.

PORT           CODEC     VAD VTSP STATE            VPM STATE

============== ========= === ==================== ======================

x/x/x     g711ulaw   n  S_CONNECT             FXSLS_ONHOOK

I see this message in the logs only on the effected port. Other ports are not having this log generated.

%FLEXDSPRM-3-TDM_CONNECT: failed to connect voice-port (0/x/x) to dsp_channel(0/0/1)

Need some one to assist me on this issue.

That sounds like a hardware error with the DSP. I would suggest power cycling the gateway (not just a reboot). If that doesn't work then you most likely have failed hardware.

[Nikhil.ranjan]

Only one port is having issue, others are working fine. Could this be issue on the Paging device as well. 

[Elliot Dierksen]

That is possible but the message points to hardware on the port. If you connect a regular handset to the port, can you get a connection?
