Connect Exotel SIP trunking to Bolna Voice AI

this guide aligns exotel sip trunking with https //www bolna ai/ using the same patterns as the other voice ai integrations in this repository outbound exotel = create trunk → map did → credentials; inbound = destination uri on the trunk; connect = sip \<trunk sid> ; acl = static ips only (mask 32), no cidr ranges on the trunk github repo (reference) https //github com/exotel/agentstream voiceaiecosystem applicability hybrid — byot is api/config driven (sip trunk objects) and may also have portal steps depending on account access (sip is beta) outbound sip is supported with byot, bolna places outbound pstn calls over sip through your trunk it resolves from number to your trunk, then signals to your gateway (exotel edge ip\ port ) using userpass (or ip based ) auth that is the flow described in make outbound calls via your sip trunk part b below is exactly what exotel needs on the carrier side for that outbound sip leg bolna also offers a dashboard connector for exotel (rest api link) — see connect your exotel account to bolna this article focuses on sip byot where you configure exotel sip trunking and a bolna sip trunk together bolna sip trunking is beta ;
