Cisco UCW subject matter experts will monitor and reserve the right to have final say in the content. The focus of this particular document is all things releated to troubleshooting a UCW solution. Make sure you have upgraded the UCW and any other network equipment such as switches to the latest released version of firmware. Often times problems have been addressed in the latest software.
However the Auto Discovery is made only when the Switches are in factory default state. Plug a powered up UC into the switch and then please factory reset the switch to re-enable auto-discovery. If not, configure them manually using "Smart Designs". Please disable CDP on other routers. Also Trunk and Access ports have to be configured. Please see switch manual. Then at prompt enter the restore defaults code Try browsing directly to the IP address e.
Refresh the page if necessary and click on the icon or discovered web interface link to access the UCW. Sometimes configuration conflicts prevent accessing the UCW.
ESW switches must be upgraded to at least the 2. Verify that connectivity problems are not caused by a misconfigured switch by connecting PC directly to UCW. Blank Web Browser Ensure you are using a supported browser on an supported platform Web browser: Internet Explorer version 7 or 8 or Mozilla Firefox version 3.
Access Error firmware prior to 2. Prior to 2. Upgrade the firmware to 2. The Configuration Utility will show in your native language, provided it is supported, otherwise will show english. Make sure you using a supported browser and the latest Adobe Flash Player installed see above. Close all unnecessary browser windows and tabs. Ensure that you have adequate amount of RAM and virtual memory Upgrade Application loads a large file into memory and memory required can exceed Mb.
If you still have issues and are able to, try using a different PC or browser as a fault isolation step. If you are still unable to upgrade, try rebooting your PC and relaunching your Configuration Utility browser.
Ensure network time protocol NTP is allowed through any external firewalls. Ensure timezone is set correctly on the Region page. Determine which end is hearing the echo. If the PSTN caller is hearing echo, make sure the echo complaints are not due to phone issues such as handset and speaker volumes being too high or untested headsets being used. If possible, call a digital phone. Be sure to mute the microphone at the called phone during the test.
Try calling VoiceMail and leave a message then compare the volume of the stored prompts to the message volume level and see how they differ. Take note if one is one considerably louder than the other.
If after running Impedance Matching Tool you are still experiencing poor volume levels, try to change the audio gain settings. Try making changes to phone volume levels first. Crosstalk Check your cabling to make sure connections are good. The default VLAN and QoS configuration for UCW is carefully optimized to avoid these types of issues and if you are experiencing problems in this area, it is likely due to the configuration of another node in your network. Ensure switch firmware is updated and current.
Ensure switch spanning tree is configured for portfast. Ensure switch is set up to auto-negotiate the Duplex Mode. Ensure there are no Ethernet hubs in the network. Ensure any automated dialers provide a pause if using PBX mode to give the UCW time to provide outside dialtone and collect the rest of the address. Automated dialers typically allow you to enter a pause code.
Echo Because SIP trunks are digital, they have fewer echo issues than analog trunks. However, complaints in this area might be due to issues in other areas such as: QoS configuration of components other than the UCW such as a switch or upstream router. Therefore complaints about audio volume are likely better addressed in another area of the product like making sure volume levels at the phone are adjusted to compensate.
Therefore complaints about noise level on SIP trunks are likely better addressed in another area of the product like making sure ambient room noise conditions where the phones are located or other acoustically coupled sources are properly controlled. These files can be created on and obtained from the Small Business Support Center.
Ensure QoS is configured on any upstream router such as SA on the premise. Problems with external MOH source if configured. Make sure connections and levels are adequate. Note: this problem would also exhibit itself on MOH for internal calls as well and can be ruled out as an issue if those work properly.
These types of issues are usually traceable to the configuration of a specific phones. In other words, Callers from both inside and outside the office might experience echo when talking to people at certain phones. Possible solutions for these types of echo complaints include. Lower and save the handset and speaker volume at the phone. In some cases it might be necessary to increase Rx gain at FXO trunks to compensate but usually just lowering the volume at the phone will resolve the issue.
Sometimes headset volume levels can also contribute to problems such as echo. Make sure the headset being used is one of the approved and tested headsets. Some headsets that plug into the SPA phone handset interface have exhibited echo problems that are resolved by replacing them with approved units that use the headset interface of the phone instead of the handset interface.
Volume All SPA phones provide speaker and handset volume settings that can be saved off and retained after phone reset. This is always the first level attack to a volume problem.
Be careful though to not set volume levels too high as these can lead to other complaints such as Echo. Noise Make test calls to try to trace the noise problem to a specific phone or trunk. If it is traced to a phone, check your handset cabling to make sure connections are good. If the problem is traced to a specific phone, make sure your handset is properly connected. If the problem still occurs, try swapping out the handset with another phone and see if the issue follows the handset.
If that is the case, the handset might need to be replaced. Ensure there are at least 4 bars of signal strength on the SPAG 2 phones. Because the phones use Repeat this until all ports are used taking note of the order that the Service Provider selects the incoming port.
Dropped Calls The UCW is automatically pre-configured to detect disconnect supervision using a number of methods including: Battery Removal configurable timed loss of loop current. Battery Polarity Reversal.
Disconnect Tone configurable single or multi tone signal to detect as "Call Disconnect". Disconnect Tone specified duration, and single or multi tone frequencies to detect as "Call Disconnect". A side effect of an FXO line not disconnecting properly are voicemail messages that are 10 minutes in duration maximum voice message size filled with an extended period of silence or tones.
Not Registered If your SIP Service Provider requires registration for any reason your registration fails you will not be able to make outgoing or incoming calls. Make sure your WAN connection is up and stable. Alternatively you can capture packets on the WAN Interface using a network sniffer.
Reset your UCW and look for your Registration message looking to see if the Registration is sent and possibly rejected. See if the reject reason helps understand the issue to be corrected.
Service provider based voicemail and other services that may provide a stutter dial tone or non-standard dialtone can cause DTMF digits to be missed. Verify the dial tone by connecting an analog phone to the FXO line and listen to the dialtone when going off hook.
It is unlikely to fail but in the rare instance that this is too fast for the Service Provider, it might result in outgoing call failure because the some of the initial digits may be missed. This value should not be increased. This value is beyond the control of the UCW configuration.
Time to answer called party phone. Dial Plan Issues The UCW is configured automatically with a default Dial Plan template for phones and trunks based on the Region you set when configuring your system. This should be adequate for all common dialing practices for the selected Region. FXO lines that are from a Centrex provider have special dial plan requirements are not supported at this time. This is true even for calls that are call forwarded external, transferred external or a hairpin through the UCW.
If the called party telephone is showing something other than this provisioned ID, you can take the following steps to troubleshoot the problem.
If you see the correct ID in the outgoing INVITE message, open a trouble ticket with the Service Provider to make sure the feature is enabled and to look into the problem on their side. If you sometimes see an incorrect or no Caller ID on an incoming call.
If Caller ID is not provided to the POTS phone or Buttset , take the following additional steps: Check for cabling issues or look for sources of signaling impairments cross connected cables, shorted wires, etc.
Check to see if the Rx Gain has been increased on this FXO port and try lower the value to see if it resolves the issue. In the US, the typical cadence is 2 seconds of Ring Voltage followed by 4 seconds of silence and repeating until the call is answered or abandoned. This is normal for Loop Start Trunk interfaces.
