Hi Neal,
disappointed of haslemere! - Followed your guidance and the problem persists
The detail in your post suggests you are familiar wioth VoIP systems?
I am a new partner with Entanet and their support team has been very willing and active in trying to help me but somewhat unsuccessful!
I installed an xLite softphone on a laptop on the customers network. This works perfectly!
So, this suggests that the problem lies with a handset setting as the same router and network was being used?
BUT... I plugged one of the handsets into my own network and if I opened all UDP ports on my router, or indeed just 5060, it worked!!
This in fact points to the router!!
The only difference I can find is that my Netgear router has SIP ALG enabled (or to be more accutae it is NOT disabled).
I cannot find how to verify if the 2710n has a similar setting - it isn't immediaely obvious in the actual web interface and I cannot find it in the manual?
Any ideas?

I found another thread similar to my issue which suggested isuong sys sip_alg 0 via the telnet interface.
Tried this and also sys sip_alg 1
neither solved the problem
