VOIP Issues

I have a VOIP system that can make outgoing calls but on incoming calls the VOIP Phone rings but when I answer there is no voice at all, however if I put that call on hold, then take the call back it all works.

HELP Please?

Re: VOIP Issues

Does that router have a SIP ALG setting somewhere, maybe in its Firewall? Try reversing it.

I was told by EE small business support that EE does not support VoIP

Re: VOIP Issues

No technical reason why it shouldn't work. They just won't help you with it.

 

Didn't switching SIP ALG help? Did you reboot router after changing it?

 

Have you port forwarded any ports for VoIP?

Re: VOIP Issues

The router works perfectly using a Vodafone SIM card so VoIP settings are ok, I can make calls from the VoIP telephone, I can receive calls but when you answer there is no voice, the other strange thing is that if the incoming call is put on hold then taken off hold everything works

Re: VOIP Issues

Yes, so you keep telling me but the router doesn't works properly using an EE SIM. So I'm suggesting you reverse a SIP ALG setting or similar in the router when running the EE SIM. Have you? Not the VoIP's settings themselves.

Re: VOIP Issues

We have tried the SIP SLG setting and it makes no difference

Re: VOIP Issues

It has been reported that the EE Content Lock that is enabled by default on EE Business accounts was causing the issue of lost dropped voice data packets after call initialises. You may have to call your a/c mgr. to disable this.

Re: VOIP Issues

I went through months of the same problem. After various poor attempts to deflect the issue by technical support (IPV6, bad software, broken sim, trying on Android phones, blaming the VOIP provider) I finally got an admission it just does not work.

I think it was when I told them the same phone with the same sim with same software worked when I roamed abroad made them realise they had no argument left.

I was then told it was tough luck as they didn't promise to support VOIP explicitly. I said that on a business account, VOIP should be a given and that their agrument was akin to saying that if YouTube didn't work on ee's network it wasn't their problem either. 

Anyway, I got a 50% discount on buying myself out of the contract. O2 and Three work perfectly on VOIP so if it's an issue I suggest you vote with your feet.
