Hi,

I have greped this forum relating use of alphanumeric originating address in GSM MT SM scenario - e.g. ESME (SMPP Application) sends SM with Originating Address: "hello".

Some posts say that alphanumeric OA (or source address) is applicable but the reply to such an address will not work. The posts what I have found do not distinguish between local and foreign users.

I understand that reply can not work to an alphanumeric address if MT SM is received by a foreign user (reply SM is routed to different SMS-C).

But I do not understand why a local user can not reply to an alphanumeric address if the SMS-C can route the SM to the appropriate ESME (SMPP application).

Please correct me if I am wrong.

What you are telling is absolutely correct, but does your mobile allow you to send a message to 'Aphanumeric' destination address Huh

It can happen that a particular mobile subset does not allow a feature supported by the protocol itself.

Do you mean that use of alphanumeric SME destination address in a MO_SM is not supported by SMS Point-to-Point Protocol (GSM 03.40)?

If yes, can you give me a link where that restriction is defined?

Thank you in advance!

Routing to destination ESME is property of SMSC. That comes under client-server architecture and routing. Maintaining routing information against alphanumeric-address is not a big deal in SMSC.

But does GSM network allow to send a message to alphanumeric address.. I doubt.

Though in MO SMS the destination address is packed in the payload and has no relevance in routing till it reaches SMSC. But does phone allow some one to send a message to alphanumeric number ?
