voice on 2801 with VIC3-2FXS/DID

hi,

VIC3-2FXS/DID which is update version of VIC2-2FXS is not function well although configuration is same as vic2-2fxs, I can able to dial and there is ring but after picking by receiver within seconds line get disconnected I can hardly hear hello**!! from otherside then it cuts. this is happening on both ports.

other details on this issue:

orignal card vic2-2fxs of 2801 was damage so i have to get new but same model is now out of sale & replacement is vic3-2fxs/did.

  

new card vic3-2fxs/did was not detected so I have to update IOS ipvoicek9mz.124-20T on 2801 

copied same configuration (vic2-2fxs which was running smooth but using other version  IOS)

!

voice-port 0/0/0
input gain 7
cptone BR
timeouts call-disconnect 5
timeouts wait-release 5
!
voice-port 0/0/1
input gain 7
cptone BR
timeouts call-disconnect 5
timeouts wait-release 5
!

dial-peer voice 112 pots
destination-pattern 112
port 0/0/0
!
dial-peer voice 113 pots
destination-pattern 113
port 0/0/1
!

I notice when i tested sound card localy (hooking telephone sets on both ports) and if i dail number there is ring and sound is good no disconnects no issues atall but when router sends to branch and connects to telephone sets and dail the number from other branch it rings and disconnects after receving hello.

voip configuration (same config is working fine with vic2-2fxs)

Re: voice on 2801 with VIC3-2FXS/DID

sounds like a media nego/codec issue if the call drops on answer.

following debugs along with dialpeer config (in use)will be a good start

deb vpm sig

deb voip ccapi inout

Same config, some seconds of voice are heard, and codec issue ? Unlikely.

I would recommend update IOS first.

Re: voice on 2801 with VIC3-2FXS/DID

Dear Palo, version what i am using must work am i correct?? becoz i found this on cisco link (VIC3-2FXS supported IOS on 2800 are

12.4(15)XZ or 12.4(20)T).

dont you think that it need addidtional configuration. (apart from vic2-2fxs config)

how can i get/download the version you suggested. please provide link, thanks

Perhaps the other side doesn't support battery reversal for answer supervision?  Try 'no battery' under the voice port, and shut/no shut to take effect.

If the issue still persists, get CCAPI inout and VPM sig debugs during the issue.

Re: voice on 2801 with VIC3-2FXS/DID

no battery- reversal command doesnt effect.

voice still drops in 2-3second after picking receiver.

pls. suggest any other commds. thanks
