<!-- Kamailio Project uses GitHub Issues only for bugs in the code or feature requests. Please use this template only for bug reports. If you have questions about using Kamailio or related to its configuration file, ask on sr-users mailing list: * https://lists.kamailio.org/mailman3/postorius/lists/sr-users.lists.kamailio… If you have questions about developing extensions to Kamailio or its existing C code, ask on sr-dev mailing list: * https://lists.kamailio.org/mailman3/postorius/lists/sr-dev.lists.kamailio.o… Please try to fill this template as much as possible for any issue. It helps the developers to troubleshoot the issue. Note that an issue report may be closed automatically after about 2 months if there is no interest from developers or community users on pursuing it, being considered expired. In such case, it can be reopened by writing a comment that includes the token `/notexpired`. About two weeks before considered expired, the issue is marked with the label `stale`, trying to notify the submitter and everyone else that might be interested in it. To remove the label `stale`, write a comment that includes the token `/notstale`. Also, any comment postpone the `expire` timeline, being considered that there is interest in pursuing the issue. If there is no content to be filled in a section, the entire section can be removed. You can delete the comments from the template sections when filling. You can delete next line and everything above before submitting (it is a comment). --> ### Description <!-- Explain what you did, what you expected to happen, and what actually happened. --> Hello, when I was testing the SMSC SMS business, I found that the SMS could not be forwarded by the SMSC when the characters were too long, approximately 117 characters. The issue was traced back to the smsops module, which has a limit on the length of the SMS, but it seems that it does not handle SMS segmentation. The error message returned is as follows. Could you please provide some suggestions and help? ### Troubleshooting #### Reproduction <!-- If the issue can be reproduced, describe how it can be done. --> #### Debugging Data <!-- If you got a core dump, use gdb to extract troubleshooting data - full backtrace, local variables and the list of the code at the issue location. gdb /path/to/kamailio /path/to/corefile bt full info locals list If you are familiar with gdb, feel free to attach more of what you consider to be relevant. --> ``` (paste your debugging data here) ``` #### Log Messages ``` 2024-04-24T05:59:01.837950514Z 3(24) ERROR: <script>: SMS for "" (Valid: 0 ) 2024-04-24T05:59:14.466167796Z 2(23) ERROR: <script>: 3GPP-SMS: MESSAGE (sip:+8618107550088@ims.mnc011.mcc460.3gppnetwork.org (172.22.0.20:6060) to tel:+8613800138000, bnecb4LQJ(a)10.46.2.1) 2024-04-24T05:59:14.466173859Z 2(23) ERROR: smsops [smsops_impl.c:1055]: decode_3gpp_sms(): Length of TP-User-Data payload exceeds maximum length! 2024-04-24T05:59:14.466175929Z 2(23) ERROR: smsops [smsops_impl.c:1320]: pv_get_sms(): Error getting/decoding RP-Data from request! 2024-04-24T05:59:14.466191554Z 2(23) ERROR: smsops [smsops_impl.c:1055]: decode_3gpp_sms(): Length of TP-User-Data payload exceeds maximum length! 2024-04-24T05:59:14.466194545Z 2(23) ERROR: smsops [smsops_impl.c:1320]: pv_get_sms(): Error getting/decoding RP-Data from request! 2024-04-24T05:59:14.466196517Z 2(23) ERROR: smsops [smsops_impl.c:1055]: decode_3gpp_sms(): Length of TP-User-Data payload exceeds maximum length! 2024-04-24T05:59:14.466198406Z 2(23) ERROR: smsops [smsops_impl.c:1320]: pv_get_sms(): Error getting/decoding RP-Data from request! 2024-04-24T05:59:14.466200311Z 2(23) ERROR: <script>: SMS for "" (Valid: ) 2024-04-24T05:59:14.466255812Z 2(23) ERROR: smsops [smsops_impl.c:1055]: decode_3gpp_sms(): Length of TP-User-Data payload exceeds maximum length! 2024-04-24T05:59:14.466276249Z 2(23) ERROR: smsops [smsops_impl.c:1903]: isRPDATA(): Error getting/decoding RP-Data from request! ``` #### SIP Traffic <!-- If the issue is exposed by processing specific SIP messages, grab them with ngrep or save in a pcap file, then add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site). --> ``` ```  ### Possible Solutions <!-- If you found a solution or workaround for the issue, describe it.
