Hi,
I'm new to VoIP and i'm hoping that somebody can help me with the issues i'm having.

I signed up with INX Logical Exchange at the begining of August and downloaded the INX PRo application. I have a VoIP Voice 500 IP phone which connects to my laptop via the USB port. It works fine for outgoing and incoming calls, but the softphone doesnt send a ring to the Voip phone. Therefore if I'm not looking at the screen i dont know if there is an incoming call. I downloaded Ahead SIPP and that seems to work fine, but it has been crashing after every phone call, so i decided to get a IP Phone based on INX's recommendation. In comes the Granstream BT100...

I set up the phone with INX's protocols. It works fine for incoming calls, but outgoing calls have been a headache and i'm at my wits end right now in terms of configuration. I've used the Configuration wizard on this website and it doesnt work. If i remove the STUN server setting, i get dial tone and I am able to dial my jamaican numbers, but the main reason i got the number was to dial toronto local area numbers. I am told that it does terminate on the destination numbers, but voice and ring tones are not delivered to the BT100, so i have no idea whether or not the call is terminated.

I'm using a Belkin Wireless Router and a Alcatel Speedtouch Pro Modem/Router. I would appreciate any suggestions that anybody could put forward, if they've faced a similar problem.

Synopsis:
1. Local incoming number from INX Logical Exchange - 416 area code
2. Calls are apparently terminated on 416 numbers, voice/ring tones arent delivered
3. incoming calls work
4. outgoing calls only dial international numbers outside the USA.

A little clarification is in order here. From the perspective of the Grandstream, what specifically is the difference in behavior between your scenario 2, Toronto, and scenario 4, Jamaica? You say that when you call Toronto you cannot hear the Call Progress Tones in your ear. How about when you call Jamaica? When you call Jamaica do you hear the Call Progress Tones or do you just hear your Jamaican phone ringing in the other room and go pick it up?

A. With Jamaica, the call progress tone is delivered and it does ring. Voice is delivered.

B. With the Toronto numbers, the call progress tone is NOT delivered, BUT apparently it does ring on the other end, but when the caller answers, no voice is delivered. - so not call progress tone & no voice.

It sounds like you are experiencing a CODEC mismatch problem when you call Toronto that does not present itself when you call Jamaica. I would suggest consulting INX's Customer Service or FAQ and make sure that your Grandstream's configuration agrees with INX's requirements in this regard.

[bbennetteasy]

You could be right. I did some tests with my friend in Toronto. Apparently she does hear my voice, but hers isnt returned to me. So, i'll mess around with the codec settings some more later on. Will update you when i'm done.

[mberlant]

If she hears your voice but you don't hear yours it is very unlikely to be a CODEC problem, since it is all but unheard of for CODEC negotiation to succeed for only one half of the conversation.

Since you are calling both Jamaica and Toronto via INX and since the only difference between placing these two different types of call is the number you dial, it looks like the problem is within INX. I recommend you contact their Customer Service and see what they can do for you.

I have been speaking to INX Customer Service for almost week before I joined this forum and they've given me a million reason why its not their service thats the problem. They're suggesting now that I try G.711, but state they dont think the Codec is the problem either. First they told me that they dont support the IP Phone, then they told me the only offer limited support for the IP phone and only the recommended ones. They only changed their tune when I indicated that it was infact a recommended phone.

All the suggestions before hinged on my being behind a firewall and NAT settings affecting how the calls connected, which incidentally didnt make any sense to me because it still worked when I called Jamaica and just wouldnt work with Toronto number. Now the suggestion is that their is an issue with my phone. Which doesnt make sense either. How can it be an issue with the phone if it works with one number and not another? I decided to humour them and connect via dialup, share the internet connection, and plug the phone into the ethernet port on my PC. It had excatly the same result as being plugged into either the modem or my router. No difference in the end result.

The fact is it think INX's Customer Support, as helpful as they were eventually, dont have a clue either.

I will try changing the codec setting today though, when i get home and see how it works. or not. If not i believe i may have exhaused all avenues to solve the problem.

[bbennetteasy]

Problem solved. Nothing to do with Codec settings. INX Changed Routing tables and guess what? Problem disappears.
