3CXPhone(ver.6) Call Transfer issue with Siemens

[Kashif Usman]

Hi Friends,

I am using 3CX Phone(ver.6.0.26523.0) on Win7 platform in integration with Siemens HiPath3800 VOIP exchange, I am able to successfully login with Siemens SIP extension on 3CX Phone application and establish extension to extension calls but when transferring calls from 3CX Phone application to any other extension (either 3CX SIP Client or generic Siemens extension) its prompting message "server unreachable", also I've followed the transferring procedure mentioned in the attached document of 3CX Phone Configuration with Siemens.

Please guide me in this regard...

Thanks & Regards,
Kashif Usman.

Re: 3CXPhonePC/3CXPhoneAndroid Call Transfer issue with Siem

Like to add one thing more, I've successfully installed "3CXPhone for VOIP Provider" on my Android cell phone and its working fine for both incoming and outgoing calls, but I'm not able to transfer calls from 3CXPhone application of my cell, while doing so it prompts "Transfer Fail", I've tried to change settings of Siemens IP interface HG1500 (Protocol Varient Extended fast connect option) but still same problem persist, also have tried to change SIP Protocol setting on 3CX from UDP to TCP but response is same.

I'll appreciate if someone could help on this.
