SMS Sender Name Using Alphanumeric Characters

Hi Community, Is it possible to send SMS using alphanumeric characters as a sender address? We tried it using an Open-Source SMS GW and it can send alphanumeric information in the sender address. Unfortunately, the SMS sent through API was not received to the test phone and the logs below are seen in OSMO-MSC. <000c> smpp_smsc.c:729 [entropy] Rx SUBMIT-SM (09170000023/1/1) <0017> sms_queue.c:155 Sending SMS 259 failed 0 times. <0017> sms_queue.c:155 Sending SMS 259 failed 0 times. <0017> sms_queue.c:155 Sending SMS 259 failed 0 times. <0017> sms_queue.c:155 Sending SMS 259 failed 0 times. <0017> sms_queue.c:155 Sending SMS 259 failed 0 times. <0017> sms_queue.c:155 Sending SMS 259 failed 0 times. <0017> sms_queue.c:155 Sending SMS 259 failed 0 times. <0017> sms_queue.c:155 Sending SMS 259 failed 0 times. <0017> sms_queue.c:155 Sending SMS 259 failed 0 times. <0017> sms_queue.c:155 Sending SMS 259 failed 0 times. <0017> sms_queue.c:155 Sending SMS 260 failed 0 times. <0017> sms_queue.c:155 Sending SMS 260 failed 0 times. <0017> sms_queue.c:155 Sending SMS 260 failed 0 times. <0017> sms_queue.c:155 Sending SMS 260 failed 0 times. <0017> sms_queue.c:155 Sending SMS 260 failed 0 times. <0017> sms_queue.c:155 Sending SMS 260 failed 0 times. <0017> sms_queue.c:155 Sending SMS 260 failed 0 times. <0017> sms_queue.c:155 Sending SMS 260 failed 0 times. <0017> sms_queue.c:155 Sending SMS 260 failed 0 times. <0017> sms_queue.c:155 Sending SMS 260 failed 0 times. We also tried sending SMS with only Numeric information in the sender address and the SMS was received successfully by the test phone. We can share the traces taken and the configurations used if needed. TIA. Best Regard, Ron Menez ron.menez@entropysolution.com<mailto:ron.menez@entropysolution.com>
