SIP REFER TRANSFER and to choose between outgoing realm / next-hop / SIP agent
Hi Community,
We have two SIP Service Provider (SP) links connecting to a NN 3820 (SCX6.4.0 MR3) SBC at a call center office.
+---------------+
| SIP agent 'A' | +---------------+ +---------------+
| (SP-A) | +------->-+ | | | +----+
+---------------+ | Net-Net SBC | | IVR / media | | |
+---------------+ | +-------+ server +------+ |
| SIP agent 'B' | +------->-+ | | | +----+
| (SP-B) | +---------------+ +---------------+ call center
+---------------+ agent phone
We need to setup the SBC to support the following:
- if any incoming call coming through the service provider SIP-agent 'A' is answered by a call center agent and then if that call is transferred by the call center agent to 'any' external number, the transferred call should go back through the same SIP-agent 'A'
