Inbound call from ASTERISK drops at 15min when re-invite is sent (420 bad extension) - need HMR
Call fails due to the setting Require:timer in the re-invite, then my SBC responds with a 420 Bad Extension. I built an HMR to replace Require:timer setting to supported, however calls are still dropping at exactly 15 minute when the re-invite comes. Has me wondering if I built this HMR incorrectly?
Also note - I am unable to change anything from the ASTERISK ... None at all
