"Invalid source address" exception when sending SMS using SMPP Server

Question

Everything was working fine for us from last 8 months and suddenly we started getting this error.

We configured SMPP driver properties in Oracle EM console and sending SMS using UMS integrated with Oracle SOA server.

Found a link related to this error but it doesn't help:

We figured out and resolved this issue. Posting its resolution here. May be it can help someone other and save their precious time.

SMPP driver configured in Oracle EM console has a bug due to which Source address and Default source address are always null even if you pass it from driver configurations.

It was due to multiple Source Address at SMSC and our system was passing null value in Source Address field. Due to this SMSC was not able to recognize correct source address and throw "Invalid Source Address" exception.

If single/static source address is configured at SMSC then you can pass null values and SMSC will automatically recognize source address.
