thanks david for your response
this call is generated by asterisk and connected to the sip provider so do you think if i stoped early media in sip.conf would change anything.
regards
No. It is the provider that is probably using early media and in band progress.
Is this provider one that aims at the PABX market? If so, they may want to make their system more PABX friendly. If they are really in the single IP phone market, they may not care.
it actually a gsm operator connected with E1’s to our dialogic bdn2020 that converts to Sip to asterisk .
is it possible that it may be a miss configuration in the dialogic then ?
