SRST881 FXO Port (UK) - phone keeps disconnecting during ringing

[jason.henderson]

Hi all,

I have this issue with an FXO port where if i make an inbound call to the port, the IP phone rings for less than a second, cuts off, rings for less than a second, cuts off, and so on.  On the mobile i'm making the call from, it sounds fine.

Config i have at the moment is -

voice-port 4

translation-profile incoming Inbound_Call

translation-profile outgoing Outbound_Call

cptone GB

impedance complex3

description *** PSTN Fallback ***

caller-id alerting line-reversal

I can't find anything online describing this issue - could it be something to do with the BT wall socket being either a master or a secondary, or a supervisory-disconnect issue?

Thanks in advance,

Jason

Jason,

Can you change the voice port

!

voice-port 4

no caller-id alerting line-reversal

caller-id enable

caller-id alerting dsp-pre-alloc

supervisory disconnect dualtone mid-call

!

Let us know if this helps

Regards

Alex

Jason,

Normally we need to use PLAR to direct the call to a specified number.

I do not see any PLAR here

What does the Translation profile (Incoming): Inbound_Call

contain

Hi Alex,

See below.  4004 is an internal extension i'm using for testing, but the PSTN line is supposed to be for local 999 breakout, so incoming working is not essential.

In CUCM, i have a route group configured to send any emergency numbers to the 881, but when i try an outbound call i get a Disconnect Cause=34, which i believe means no cct/channel available.  Some debug below as well -

sh deb

CCAPI:

  debug voip ccapi error call is ON (filter is OFF)

  debug voip ccapi error software is ON

  debug voip ccapi inout is ON (filter is OFF)

Voice Port Module signaling debugging is on

It appears that there is no dial tone on the line

Can you check that a POTS phone works on the wiring.

Can you also make sure that the wiring is correct

FXO --RJ11 ---3 -------  BT PSTN JACK  2

FXO --RJ11 ---4 -------  BT PSTN JACK  5

You must make sure that these are the only wires connected.

Also try a pair reversal

Cannibalised the RJ11-BT wiring, and it's now working...  Thanks!!!

So if i'm buying the correct RJ11 - BT male wire, what am i looking for?

Cheers

Jason

[acampbell]

Jason

I normally use any old RJ11 cord , cut off the other end and Krone the wires from Rj11 3 & 4 (ONLY)

on to the BT wiring 2 & 5 in a jack.

In bigger offices etc the FXO lines appear on the Krone strip or an RJ45 panel

Another note is if it is RJ45 then the pair should be on RJ45 -4 & 5 (Usually the blue/blue-white)

I have a simple question, the 881SRTS router can be register with a CUCM 7 and work has a remote gateway (SCCP,MGCP or H323) with FXO lines ?

[acampbell]

Hi,

Looks like you are correct

http://www.cisco.com/en/US/docs/routers/access/800/860-880-890/software/configuration/guide/overview.html

Voice Features

The Cisco 880 voice and data platforms (C880SRST, C880SRSTW, C881-V, C887 VA-V, and C887VA-V-W) support the following voice features:

•Signaling protocols: Session Initiation Protocol (SIP), Media Gateway Control Protocol (MGCP), and H323

•Real-time transfer protocol (RTP), Cisco RTP (cRTP), and secure RTP (SRTP) for these signaling protocols

•Fax passthrough, Cisco fax relay, T37 fax store-and-forward, and T.38 fax relay (including T.38 gateway-controlled MGCP fax relay)

•Dual tone multifrequency (DTMF) Relay—OOB and RFC2833

•Silence suppression/comfort noise

•G.711 (a-law and u-law), G.729A, G.729AB, G.729, G.729B, G.726

•Support of SRST failover to a Foreign Exchange Office (FXO) or BRI backup port connected to PSTN in case of WAN failure on C880SRST and C880SRSTW.

•Support for SRST and CME requires user license, but only a 5-user license is supported on C881-V, C887VA-V, and C887VA-V-W routers.

•Direct inward dialing (DID) on FXS
