Hi SupportSysE,

There are several versions of TLS that your provider(s) may be using, do you know whether it is TLS 1, 1.1 or 1.2? When you connect you have to match the TLS version exactly otherwise you get the response you can see below. In the absence of that info from your provider it would be ...

Hi Alt,

I was referencing the VB.NET project and EnquireLink does not work within that. I have now referenced the C# version and EnquireLink DOES work in that version so I'll stick with that, thank you.

I'm not that great with C# and the C# project is throwing up the following warnings which I ...

Hi Alt,

I have integrated v1.1.28.0 of the source code you sent me (thank you) but it appears the EnquireLink functionality is broken in this version - it never sends an EnquireLink to the SMSC regardless of NeedEnquireLink=True.

Nick

Hi Alt,

Regarding SmppServerClient. I have a product published into Azure using this component and have been fighting a losing war with the Azure load balancers which open TCP connections every 15 seconds to each Cloud Service to monitor it's 'UP' status. Unfortunately this connection is being ...

Ah fantastic, thank you for the update! :)

I'll email you for a link to the new source code.

Hi Alexey,

Thanks for your response.

Unfortunately changing both of those properties doesn't modify the DeliverSm, after serialising and then deserialising it the previous MessageId is still present in DeliverSm.Receipt.ToString (The DeliverSm I am receiving doesn't use the option parameters ...

Hi

Has anyone managed to modify the MessageId in a DeliverSm to replace the existing one? No matter how I go about it the modifications are always overwritten when I serialise and then deserialise it :(

Help appreciated!

Hi Alt,

I have a problem with the SmppServer class becoming unstable when a client attempts to connect using an unsupported SSL protocol (such as Ssl2, Tls11, Tls12) - such that it brings down my entire app. I'm not sure how to recover from the situation, any advice?

Regards
Nick

Hi Alexey,

Ah yes the most recent version does have that, thank you :)

My problem now lies in our legacy application using v1.0.12.3 which does not, I guess I'm going to have a busy 24 hours!

Thanks and regards
Nick

Hi Alt,

I received a notification over the weekend from an SMSC provider that they are deprecating SSL support in favour of TLS on the 11 November (Yes, they gave us 3 days notice!!). Is TLS support something you are looking at implementing? and if so, when?

Thanks you.

Hi

I am using v1.1.15.5

I can serialize the DeliverSm however upon deserializing I am receiving:
System.NullReferenceException: Object reference not set to an instance of an object.
at Inetlab.SMPP.PDU.DeliverSm.ReadFromBuffer(SmppBuffer buf, Int32& offset) in E:\Home\My Documents\Visual Studio ...

Hi KoolPitt,

That information has to be included in the UDH (User Data Header), you can find everything you ever wanted to know about the SMPP 3.4 protocol in this PDF http://docs.nimta.com/SMPP_v3_4_Issue1_2.pdf .

Personally I would store the original message text and data coding and recreate it ...

Hi KoolPitt,

Dim m_SmppClient. As Inetlab.SMPP.SmppClient = New Inetlab.SMPP.SmppClient

Dim listOfSubmitSm As List(Of SubmitSm) = m_SmppClient.PrepareSubmit(SubmitMode.ShortMessage, m_SourceAddrTon, m_SourceAddrNpi, SourceMobileNum, m_DestAddrTon, m_DestAddrNpi, DestMobileNum, DataCodings.Default ...

I certainly didn't want to teach you how to suck eggs!

..and I meant to write 'oSubmitList' is ending up as nothing.. it was a wee bit late!

Hope you get to the bottom of this.

Cheers
Nick

Hi,

I meant are you catching any other exception type, in the following code the exception handler will only catch the exception if it is of type SmppException.

Try
strFrom = oMsg.ChannelAddress
...
Catch smppEx As Inetlab.SMPP.common.SmppException
' Only exceptions of type SmppException will ...
