Hi Users,

It's been a while, I have a question regarding UDH, currently I have few smpp connections to SMSC and sometimes when kannel submit the long sms, it will get rejected with 'Message length is invalid'.
Further check with the SMSC they mentioned that the UDH Contains 'Extended GSM Characters ( ^ \ { } [ ] ~ |' that take 2 of the 160 characters of an sms.

Exp :

05 00 03 5c 02 01 49 54 6c 65 61 64 65 72 73 73 ...\..ITleaderss

[cid:***@01D35979.30EC1710]

Is there any way to exclude this characters from being used in UDH?

Regards,
Arif Noor

What is the Data Coding Scheme you are using ??? It may play a crucial role in SMS PP data download package. (May be you can send raw SMS packet for further information)

Hi Users,

Revisiting this case as I still getting this kind of errors when sending long concatenated message, is there any way that I can avoid this issue aside from limiting the octets by using max-sms-octets?
We have no issue with other provider only for this particular one.

Thank you and Regards,
Arif Noor

Subject: RE: UDH Length Question

What is the Data Coding Scheme you are using ??? It may play a crucial role in SMS PP data download package. (May be you can send raw SMS packet for further information)

Subject: UDH Length Question

Hi Users,

It's been a while, I have a question regarding UDH, currently I have few smpp connections to SMSC and sometimes when kannel submit the long sms, it will get rejected with 'Message length is invalid'.
Further check with the SMSC they mentioned that the UDH Contains 'Extended GSM Characters ( ^ \ { } [ ] ~ |' that take 2 of the 160 characters of an sms.

Exp :

05 00 03 5c 02 01 49 54 6c 65 61 64 65 72 73 73 ...\..ITleaderss

[cid:***@01D3B55D.D1FB2700]

Is there any way to exclude this characters from being used in UDH?

Regards,
Arif Noor
