Carrier · Cutover documentation
Generate a clean, carrier-ready SIP handoff document: signaling, codec, DTMF, CLIP/PAI, keepalive, E911 records, cutover test plan. The doc your carrier's engineer will actually thank you for.
Every SIP trunk cutover fights the same back-and-forth: "send us SDP", "what's your PAI?", "is that CUBE behind NAT?". This tool produces the one-pager that answers everything up front.
The generated document has standardized sections: network information, SIP signaling, media, DTMF, CLIP/PAI policy, keepalive, DID inventory, E911 ERLs, test plan, and go-live checklist. Copy it into your carrier's order form or attach as PDF.
The two most-debated items on any handoff: CLIP/PAI and keepalive. Most carriers prefer P-Asserted-Identity with From header mirroring for CLID. Keepalive by SIP OPTIONS is universal; REGISTER is only used for provider-registering trunks (common in SMB, rare in enterprise).
Yes — sample SDP is appreciated. The tool includes a placeholder you fill in post-install with a real pcap sample.
Mention it explicitly. Some carriers disable T.38 by default; others require separate DID blocks for fax.
SBC public 203.0.113.10, TLS+SRTP, RFC 2833 DTMF, PAI for CLID, OPTIONS keepalive 60s, 3 sites with 100-number blocks each, E911 ERL per floor.
SBC pair at two regions. Lumen gateway on their side, Webex MME on the other. Doc outlines IP ranges, auth token, and survivability.
