SoftPhone 1.3(3) and call silence

[Raymondo206]

I need some of your expert help here people.

I am trying to run a the Cisco SoftPhone 1.3(3) over Symantec VPN. I can get the SoftPhone to register with the Call Manager and am able to select the CTI port I created.

I can make and recieve internal calls OK. I can make an external call but am unable to hear anything.

I also have a similar problem with the IpBlue soft phone, only with this I can hear the recipient but they are unable to hear me.

Any help on this would be great.

Regards

Ray

What is the gateway? Don't forget the h323-gatway voip bind command on one of the gateway interfaces.

In order to get Cisco IP SoftPhone to have two-way audio when using NAT and utilizing VPN client software, make sure that you have configured the VPN ip address, instead of the configured network adapter ip address under the "network audio settings".

To get there, do the following:

Open Cisco IP SoftPhone and click the Settings icon .

Select the Audio settings tab.

Select Network Audio Settings

There are three ways to get the correct IP address advertised. Choose one of these three ways. Click OK when finished.

Automatic Selection

The Automatic Selection setting uses the file getIP.asp from the web server that you use to distribute the IP SoftPhone files to clients.

For example if the IP address of your IP SoftPhone distribution web server is 10.21.15.10 and the IP SoftPhone distribution files are shared in a directory named "ipsp" the url to use on your PC to obtain its current IP address is:

http://10.21.15.10/ipsp/getip.asp

This web application will give the following output when connected to through a browser:

172.16.240.37 /* tapiaddress.java result = provider.syncTapiObject.
SetLineAudioReceiveAddress(deviceID[0],tapiHLine, extVersion[0],
t.getIPAddress(), t.getUDPPort(), t.usesLowBandwidthCodec()); */

The address at the beginning of the response is the IP address the request came from. In this case the PC's address is 172.16.240.37. This is the address Cisco IP SoftPhone would then use when registering with the Cisco CallManager. By automating this, the need to manually enter the address every time a new one is assigned should be alleviated. Just point the automatic selection to the getIP.asp page on the Web Server. The page should be there by default when Web Administrator is installed and should be in the same folder.

Select Address



There will be a pull-down menu of addresses on the local machine. Select the one that is most appropriate.

Specify Address



The address to be advertised can be manually entered if needed.

Cisco IP SoftPhone must be restarted for the changes to take effect.
