SIP 513 Message Too Big becasue of message length
The SBC generating error message "SIP 513 Message Too Big " for the INVITE it recieve from core which has multiple via & record routes. Noticed in the debug logs that message length exceeds. But after 16 attempt SBC accept the 17the message (same message lenth) and forward to the egress core. Question is, why SBC accept the 17th message, where is the message length configured ? How can I change message length to avoid 513 messages ?
