No Audio on Phones

I don't know where I went wrong and a friend of mine can't figure it out either.

If I was to make a phone call the Cisco Phone have nothing on the speaker side of the phone. But when I call internally it's fine.

Thanks

That's not a whole lot of information?

You make a call using the cisco phone but nothing on the speaker? OK?? Are you not getting ring back? are you connected to another IP Phone and they can hear you but not vice versa? We'll need more information

What does your config look like, what model phone? what version are you running? all that good stuff, and a call example

any debugs??

are the phones registered?

show ephone is your friend

Hello,
Yes the phone does ring, when I call from my cell phone to a Cisco Phone The Cisco phone can not hear me talking on my cell but when I talk on the Cisco my cell will hear me. Its not my headset because again from Cisco to Cisco phone it works fine.

Ok, you have multiple ephones, do they all experience the same issues Off-net? how about on-net calling, sccp to sccp?

One way audio is indicative of either a routing problem, codec mis match, possibly SIP signalling if your using a SIP Trunk - please provide more information -

How is your stuff configured? SCCP to ?? what is your pstn portion? pri? sip? Is it on off-net origination only? or do you experience the same problem calling from the sccp phone?

I don't have the exact command in front of me, but check the bindings in your gateway. MGCP media?

I've definitely had the same problem before (running a much older CCM though).

I'll look it up and post it when I have access to my notes in a little while.

He's running CME which doesnt make use of mgcp control

I first want to say thanks to everyone for your help.

It have a 3745 with 1 FXO and 1 FXS.

My router is configed to user the FXS. 2-Way communication works from all extension Cisco to Cisco phone. My phones are not set up to call out yet.

But FXS to Cisco Phones only have 1 way communication.

drkat

wow guess nobody responded to this.. how are you doing? if you need further assistance let me know.

a show run would be helpful in troubleshooting

I had posted my running config but it was held up due to the link that was in the Config File.

jwb8734

Well I have been playing with this more and still no audio.

drkat

show ip route

I also dont see in your show run any voip services setup? what is your PSTN link? I see 1/1/0 and 1/1/1 but they're FXO it looks like because of your connection plar 1000

So my system is set up like this.

WRT54GL---C3524---C3745 (CME)
192.168.1.1--192.168.1.3--192.168.1.2

I have 1 FXS and 1 FXO card as seen.
WRT54GL is my gateway and DHCP. IT does have DD-WRT in it so I can make some changes but never really played with it. I only used it to make changes to the WIFI signal.

drkat

Ok so you have SCCP end points registering to the CME at 192.168.1.2

How do you complete calls inbound from your cell phone?? What service are you using to connect the PSTN to the CME

so this is all layer 2 so I'm assuming the phones are assigned 192.168.1.1 as it's gateway..

Possibly NAT on the WRT - I'd put the CME in the DMZ - I'd do a debug too

I see no dial-peers or voice services.. as well

I am using POTS via my ISP Voice Modem.

I DMZ the CME Router.

If I have no dial-peers what should I set them to.

drkat

Oh it was just a observation..

Ok I get it.. so you have your modem going into the CME for inbound calls..

OK... you're gonna want to check your codecs then and run some debugs.

I'm confused honestly... I'm trying to look at your config but ..

incoming calls

voice-port 1/1/0
connection plar 1000
caller-id enable
!
voice-port 1/1/1
connection plar 1000
caller-id enable

do a debug ccapi inout and check your dialpeer matching.. it looks like you're going to be using dial-peer 0 which is the default dial-peer

you may have codec mismatch causing the one way audio

jwb8734

What my plan is to do is each phone has it's own extension but when I get a call it rings to all phones. I think we copied the command you have above to test out the port to make sure it was not defective.

II enabled DEBUG CDAPI. I wil do some testing tomorrow.

CCAPI not cdapi

debug ccapi inout
debug dial-peer

I dont see any voip dial-peers -- i'm assuming you're hitting dial-peer 0 and well... thats your problem

If you want, we can webex and I can go over the config live and do live traces and explain it - this voice stuff can be a bit complicated when you're trying to do it all alone

I just enabled the command. I will do some testing in the AM. But just one dest shows expansive logs after almost 5 rings.

well you can put it in terminal monitor
